[Kamailio-Users] failure_route Pseudo Variable
by Geoffrey Mina 09 Apr '09

09 Apr '09

Hello, I am using dispatcher and LCR. In my failure route I want to log the IP address of the machine which responded with an error. What is the pseudo I would use for this? I tried $si, but that appears to always contain the source IP of the server which issued the first INVITE. thanks, Geoff

Hi, I've just installed openser 3.1. When I try to start the service I am getting the following error.

[Kamailio-Users] svn trunk frozen for sr integration
by Daniel-Constantin Mierla 08 Apr '09

08 Apr '09

Hello, Wednesday, April 15, is scheduled to import kamailio modules in the git repository of sip-router.org. That will become the working place for new features as Kamailio developers agreed to switch to git. From now until migration is done, developers should hold any commit for new features or cosmetic changes to the SVN trunk. The sources will be imported with entire commit log history plus lot of new patches done during last weeks to make them compile with sip-router - status at: http://sip-router.org/wiki/devel/kamailio-integration#module_integration_st… Even for bug fixes (if it is the case considering Easter holidays) we should work on 1.5 branch after a bit more private testing before committing. If some developer has important patches to commit in very short time, please reply. Cheers, Daniel -- Daniel-Constantin Mierla http://www.asipto.com/

[Serusers] SIP message generator
by Steven C. Blair 08 Apr '09

08 Apr '09

I need to place a load on our server by generating a large number of SUBSCRIBE messages with a specific Event header type. I've tried sipsak without success. We have PacketGen on a laptop but that is a confusing application. Does anyone have any suggestions for how to generate 50-100 SUBSCRIBE messages per second? Thanks,steve

[Kamailio-Users] NONCE_REUSED return code
by catalina oancea 08 Apr '09

08 Apr '09

Hello, Does anybody know in which situation the NONCE_REUSED return code for www_authenticate would appear? I understand the usage of the STALE_NONCE code, this is when the nonce expires and the servers sends a new nonce to the phone. But why is the NONCE_REUSED used and why does it occur sometimes? Should I reject or accept the registration when this code appears? typedef enum auth_result { AUTH_ERROR = -5, /* Error occurred, a reply has not been sent out */ NO_CREDENTIALS, /* Credentials missing */ STALE_NONCE, /* Stale nonce */ INVALID_PASSWORD, /* Invalid password */ USER_UNKNOWN, /* User non existant */ ERROR, /* Error occurred, a reply has been sent out -> */ /* return 0 to the openser core */ AUTHORIZED, /* Authorized. If returned by pre_auth, */ /* no digest authorization necessary */ DO_AUTHORIZATION, /* Can only be returned by pre_auth. */ NONCE_REUSED /* Returned if nonce is used more than once */ /* Means to continue doing authorization */ } auth_result_t; Many thanks, Catalina Oancea

Hi all, I know that it's possible to use a variable in XLOG for print out the IP Source. But is it possible to work on @IP_SRC (use if, avp, etc.) in ser.cfg ?

[Kamailio-Users] Path and received parameter
by Klaus Darilion 07 Apr '09

07 Apr '09

Hi! During REGISTER processing I call add_path_received() in the outbound proxy. Now if the INVITE is routed from main proxy to the client (via the OBP), the OBP as to read the received parameter from the Ruote header and use this value as destination URI. Is there a function available to perfomr this action or do I have to do it manually (parsing Route header to the get parameter)? thanks klaus

Also, when it is time to run the script to create the mysql tables, how can I tell the script to create a db named "openser2" to avoid deleting the existing one named by default "openser" ?

[Kamailio-Users] BIGINT MySQL problems in 1.5.0.
by Alex Balashov 03 Apr '09

03 Apr '09

Greetings, I just installed 1.5.0 and wired it up to a MySQL 5.0.x database, and it appears that I am getting empty/null values for BIGINT columns when accessing them from script. This is true when I do something like this with SQLOps, for example: sql_query("test", "SELECT someBigIntColumn FROM tbl", "ra"); $var(i) = $dbr(ra=>[0,0]); $var(i) will have an empty value. Same will be the case if the access subscript is not [0,0] but say, [0,1]. The problem does not seem to be specific to sqlops; the same occurs with AVPs: avp_db_query("SELECT someBigIntColumn FROM tbl", "$avp(S:bigInt)"); This is also empty. I did a debug and confirmed that the right value for someBigIntColumn is coming out of the database, and has the right data type. All that works fine. However, for some reason this value appears to be invisible within the evaluative scope of the route script. For now, I am working around it by doing CONVERT(someBigIntColumn, CHAR(20)) inside the query. However, in principle this means that BIGINT handling is broken. Has anyone else run into this?

[Serusers] 305 Use Proxy
by Rick van Rein 03 Apr '09

03 Apr '09

Hello, I am trying to setup a redirecting proxy server with Ser, but I find that my GXP-2020 phone gets into an endless loop. Is this common? The phone is configured to use my ser service which is set as a proxy. If it tries to dial things that this proxy shouldn't handle, it sends back a "305 Use Proxy" response. The phone seems to ignore the proxy and tries again. 1) Is it common for the proxy redirection not to work? I've seen it being ill-advised on iptel.org because the RFC isn't too clear how it works. 2) What would be the proper formula to get Ser to send back a proxy redirect? I may be approaching it wrongly, but I cannot find much documentation about it online. Thanks, Rick van Rein OpenFortress

[Kamailio-Users] Processing ACK.
by Carlos A. Alvarez 01 Apr '09

01 Apr '09

I am having an issue while setting up Kamailio. I using the carrierroute modules to process calls between carriers. The configuration works great. However I have and issue. On the SIP messages We are forcing all the media through an RTP proxy, however my issue has to do with the Contact field on the Message Header. While I am able to use force_rtp_proxy to replace the contact and connection fields on the SDP part of the message, I can seem to modify the Contact on the Header part. I tried using subst to change the Contact:, and while I was partly successful, it seems the ACKs going from one carrier to another are getting messed up and throwing Kamailio into a loop. We are trying to avoid providing Contact: information to our carriers. Basically keeping them from know about each other. Any ideas/help will be Greatly appreciated.

[Serusers] Running multiple instances of rtpproxy? How to set up in SER?
by Frank Durda IV 01 Apr '09

01 Apr '09

I have reached the point where a single instance of rtpproxy is about maxed-out, showing that its single process is comsuming 85% or so and climbing of the CPU available. That works out to about 600 standing calls, the bulk of which are G.711. This is a multi-processor/core system and I have several other CPUs not really doing anything, so I would like to start up multiple instances of rtpproxy, which rtpproxy says it can do, controlling them via AF_INET sockets instead of the default AF_UNIX. How you set up rtpproxy for multiple instances seems reasonably straightforward, but what you do on the SER side to let it know that these additional copies of rtpproxy exist and how you or SER divides call load between them is less clear. Is there any documentation or examples showing this done, or better still, someone with a working ser.ctl file who would be willing to show at least that part of their configuration? Ideally, I'm looking for a case where calls are divided among rtpproxies regardless of where they came from or where they are going, as I have one particular call source/destination pair that is absurdly large compared to all others, and that so it in particular has to be distributed across across multiple rtpproxies. Thanks in advance!

[Kamailio-Users] Force core dump
by catalina oancea 01 Apr '09

Hello Can anybody please help me on how to force a core dump if a child crashes? I see this: /usr/sbin/kamailio[12328]: INFO:core:handle_sigs: child process 12379 exited by a signal 11 /usr/sbin/kamailio[12328]: INFO:core:handle_sigs: core was not generated /usr/sbin/kamailio[12328]: INFO:core:handle_sigs: terminating due to SIGCHLD /usr/sbin/kamailio[12393]: INFO:core:sig_usr: signal 15 received And if I run with gdb, it says 'Program exited normally' Has anybody managed to make a core dump in this case? Thanks Catalina

[Kamailio-Users] sanity module trouble
by kokoska rokoska 31 Mar '09

31 Mar '09

Hi all, due to malformed INVITEs I'm receiving from clients I like to use sanity module. But after few test I'm affraid I don't understand correctly how it works :-) 1. I try to load the module: loadmodule "sanity.so" modparam("sanity", "default_checks", "999") and kamailio rejects config with the: ERROR:core:set_mod_param_regex: parameter <default_checks> not found in module <sanity> 2. When I comment out "modparam", kamailio starts successfuly, but: All INVITEs (from all clients) are reject through this snippet of code if (method=="INVITE") { if (sanity_check("128")) { xlog("L_ERR", "bad INVITE SDP body length from $si:$sp\n"); exit; } else if (sanity_check("1024", "7")) { xlog("L_ERR", "malformed INVITE from $si:$sp\n"); exit; } } I don't think that all of them could have bad length on SDP body (about 120 diffenet UAC types), so I assume I use "sanity" wrong way... Could you, please, shed some light to proper usage of sanity module? Thank you very much! Best regards, kokoska.rokoska

[Serusers] Network Monitoring
by Bill McNamara 31 Mar '09

31 Mar '09

We are running SER 2.0.0 under RedHat 4.5 (kernel 2.6.9). Anyone have any recommendations for network traffic analyzers, hardware or software, so we can monitor SIP traffic? We would like the solution to be able to detect dropped calls, generate statistics and possibly debug active connections. A Google search returns many hits, but I'd like to get some recommendations from folks actually running the monitors before I start looking at trial versions. Thanks, Bill

Guys, I'm getting this error on the logs for failure route but just for some of the calls I pass. If I call afterwards to that number it rings OK, so it is a random event: ERROR:carrierroute:cr_load_next_domain: during set_next_domain_recursor, prefix '1054111547533610', carrier 2, domain 1 I'm filling carrierfailureroute with an empty string when I want taht route to be the final one; is it OK to do that?

[Serusers] Common Log File
by Jiri Kuthan 26 Mar '09

26 Mar '09

I'm wondering what folks think about this the Common Log File (CLF) activity in the IETF? http://www.ietf.org/internet-drafts/draft-gurbani-sipping-clf-01.txt http://tools.ietf.org/html/draft-roach-sipping-clf-syntax-00 Comments to me or directly to the authors welcome. -jiri Abstract Well-known web servers such as Apache and web proxies like Squid support event logging using a common log format. The logs produced using these de-facto standard formats are invaluable to system administrators for trouble-shooting a server and tool writers to craft tools that mine the log files and produce reports and trends. Furthermore, these log files can also be used to train anomaly detection systems and feed events into a security event management system. The Session Initiation Protocol does not have a common log format, and as a result, each server supports a distinct log format that makes it unnecessarily complex to produce tools to do trend analysis and security detection. We propose a common log file format for SIP servers that can be used uniformly for proxies, registrars, redirect servers as well as back-to-back user agents.

[Kamailio-Users] Dealing with REGISTER "retransmissions"
by mayamatakeshi 25 Mar '09

25 Mar '09

Hello, we are running kamailio 1.4. Some days ago one of our subscribers SIP phone went crazy and bombarded our proxy with thousands of REGISTER requests. Actually, it didn't wait for any response of the proxy, it just kept sending REGISTER messages (same packet always). Since we are running with nonce_reuse disabled, it stalled the server due to "auth:challenge: failed to generate nonce". I don't have the whole figure but the packet capture I inspected showed that the terminal sent more than 200 thousand REGISTER messages in 15 seconds. We may not be able to replace those terminals at this moment. So to avoid this problem to happen again, we enabled nonce_reuse. However this only will solve the nonce problem but still we will have a lot of hits to database. So I was thinking, maybe I should create a transaction before sending the challenge so that REGISTER retransmissions would be absorbed. I was thinking in doing something like this: if (!proxy_authorize("", "subscriber")) { t_newtran(); proxy_challenge("", "0"); exit; } Does anyone see any problem/shortcoming with this? regards, takeshi

Hello, I have a couple instances of the following error in my logs. I am not sure where to start here. ERROR:core:udp_send: sendto(sock,0x2ac741ab2828,999,0,0x2ac741ab0e50,16): Invalid argument(22) CRITICAL:core:udp_send: invalid sendtoparameters one possible reason is the server is bound to localhost and attempts to send to the net ERROR:tm:msg_send: udp_send failed ERROR:tm:t_forward_nonack: sending request failed The system is being used for two things. 1 - a PSTN routing engine using the LCR module. I have two gateways in the same group with the same weight, so I suppose I am just doing round-robin load balancing on the two. 2 - a SIP proxy where I send INVITE to the Kamailio server with a Route header set with a fully qualified SIP URI. I am not sure which of these two scenarios could cause this issue... mostly because I don't really know what I am looking at. Please note, this system processed about 25,000+ successful outbound calls today, and this error only cropped up 3 times in the logs. Thanks! Geoff

[Serusers] about SER load balance
by 静于 25 Mar '09

25 Mar '09

hi~ I wonder is there any load balance sheme used by SER? If there are multiple servers responsible for a domain. One is used as main server. Suppose main server is full weight load. To which server the main server decides to relay? ___________________________________________________________ 好玩贺卡等你发，邮箱贺卡全新上线！ http://card.mail.cn.yahoo.com/

[Kamailio-Users] Using OpenSer as presence server, with OpenIMS and UCT client
by Luntras Loredana 24 Mar '09

24 Mar '09

Hello all, I have a new problem. I am using Open SER (1.3.3 tls) as a presence server with an Open IMS Core. On the event presence, the OpenIMS server redirects to OpenSER. I am also using UCTImsclient for testing. The registration is ok, the messages also. The problem is the presence: it works once and after that it doesn't work all the day. Have anyone tested all theses? Thanks for your help, Loredana

Everything now works great. Thanks again! Bill

[Kamailio-Users] [dialog module] set_dlg_profile() not working?
by Iñaki Baz Castillo 24 Mar '09

24 Mar '09

Hi, perhaps I miss something but I don't get set_dlg_profile() working: ---------------- modparam("dialog", "dlg_flag", FLAG_DIALOG) modparam("dialog", "dlg_match_mode", 1) modparam("dialog", "db_mode", 1) modparam("dialog", "profiles_no_value", "inbound ; outbound") if is_method("INVITE") { setflag(FLAG_DIALOG); set_dlg_profile("outbound"); ... ---------------- But when I run "kamctl fifo profile_list_dlgs outbound" I see nothing (the dialog does appear listed in "kamctl fifo dlg_list"). I've also added into the loose_route section: if (is_in_profile("outbound")) { xlog("L_CRIT", "*** this request belongs to an outbound call\n"); } This should appear when the ACK-200 arrives, also in any re-INVITE or BYE, but it doesn't ¿? Do I miss something? Thanks. -- Iñaki Baz Castillo

[Kamailio-Users] BIGINT in avp

Hi all, I have small (and may be stupid) question: could I store BIGNT from MySQL DB into avp using avp_db_query? And if yes, how? BTW: I tried to do it, but avp was always null. When I tried sql_query, I saw one row was red (with one column) but $dbr(ra=>[0,0]) was empty. If I changed colmun (well, better to say, I changed returning type from my stored function) to INT, everything worked well... Any hint is welcome :-) Best regards, kokoska.rokoska

[Kamailio-Users] [LCR] About ping
by Iñaki Baz Castillo 22 Mar '09

22 Mar '09

Hi, some questions about LCR module ping mechanism: - How to know which gws are down? The only I see is a NOTICE log: --------- NOTICE:lcr:gw_set_state: trunk "99.99.99.99:5060" from group: <2> is OFFLINE --------- Is not possible a MI command to list the down gateways? - Why ping_interval cannot be less than 180 seconds? - In case of failure_route and "next_gw()", is the used gw (failing gw) automatically marked as down? (it would be useful so we don't need to wait "fr_timer" seconds for each request during "ping_interval"). Thanks. -- Iñaki Baz Castillo

[Serusers] (no subject)
by Bill McNamara 20 Mar '09

20 Mar '09

We are having something of an issue with lookup_user() and lookup_contacts(). Our UA's are added to the proxy using "ser_ctl user add 1234567890(a)ourdomain.com -p password" which works great And the UA's register just fine. When a call comes in from a carrier, the invite is for 1234567890(a)12.34.56.78 where 12.34.56.78 is the IP address of our proxy. When we do a lookup to see if the call is destined for a local user via lookup_user("$tu.uid","@ruri") it fails because the registration is done using the URL and not the IP address. If I add the same user for the IP address domain, "ser_ctl user add 1234567890(a)12.34.56.78 -p password", the lookup_user() works, but the lookup_contacts(0 never does. I have tried adding aliases in the ser.cfg file: alias=12.34.56.78 alias=proxy.ourdomain.com but it does not work. I'm new to SER and the documentation I have been able to locate does not really address this issue, if, in fact, it really is an issue. If anyone could point me to something that will help me work through this problem, I'd greatly appreciate it.

[Kamailio-Users] [LCR] Can "prefix" be "empty" (any)?
by Iñaki Baz Castillo 20 Mar '09

20 Mar '09

Hi, I read in LCR doc: --------- each gateway group is associated with one or more <prefix, from pattern, priority> tuples. A gateway matches a request if user part of Request URI matches a prefix and caller's URI matches a from pattern in a tuple that belongs to the group of the gateway. ---------- Can "prefix" be empty (or NULL?) so any RURI matches it? Thanks. -- Iñaki Baz Castillo

[Serusers] Deadly embrace with rtpproxy - Is it necessary? Can it be turned off?
by Frank Durda IV 20 Mar '09

20 Mar '09

I'm running into a problem with rtpproxy on this point, quoting from the README: - - - - - - - - - - - - after the session has been created, the proxy listens on the port it has allocated for that session and waits for receiving at least one UDP packet from each of two parties participating in the call. Once such packet is received, the proxy fills one of two ip:port structures associated with each call with source ip:port of that packet. When both structures are filled in, the proxy starts relaying UDP packets between parties; - - - - - - - - - - - However, a number of clients frequently fail to emit any audio when originating a call until they hear something from the TDM gateway, such as ring-back or the called party answering. So although rtpproxy is receiving a stream of audio, such as a voice mail menu robot, the calling party can't hear any of it unless they happen to make some noise or randomly and blindly press a DTMF key. This seems to be made worse on links with silence suppression, so there is no background noise to trigger two-way audio. This is being encountered between Class 4 carriers, so we don't have the option to get someone to adjust their phone/PBX settings or have them breathe heavier. Is there a setting adjustment to get rtpproxy to just pass the RTP packets from directed calling and called sources even if one party hasn't happened to make noise yet? I personally don't understand why this requirement for seeing audio from both sides before starting the flow in either direction if audio starts coming in even exists. It seems to have no benefit but is bound to cause this deadly embrace problem in many situations that may be beyond the control of the owners of the equipment passing traffic along to the site where rtpproxy is in use. Suggestions? Fix? I have looked at the latest snapshot of rtpproxy and the README is unchanged since 1.1 so apparently this behavior is still the same. Thanks in advance!

So i did some IMS presence service tests... And Kamailio couldn't process a "SIP PUBLISH" because of an error "*ERROR 600 : Busy everywhere - Forwarding to S-CSCF failed*". For your information, i'm using the Fokus OpenIms Core as an ims server, and Kamailio as a presence server. An IFC (Initial Filter Criteria) is set up in OpenIms to route properly the presence messages to Kamailio. And by the way, i saw some lines in the logs about /tmp/kamailio_fifo opening successfully... Today, i launch the strace command and gess what... i'm getting the /tmp/kamailio_fifo opening error. Still a new kamailio_fifo is created indeed in my /tmp directory. And well, i am encountering the "busy everywhere" error again... Have anyone ever noticed the error 600? And what about the mi_fifo error that appears half the time?

[Kamailio-Users] point in the right direction
by Geoffrey Mina 19 Mar '09

19 Mar '09

hello, I am running Kamailio 1.5 and siremis. I want to deploy some IP based ACL services. Basically checking the source IP on an INVITE to see if it's in a list of trusted IP addresses. I see in the sirmeis configuration under "ACL Services" there is a tab for "trusted addresses", but I can't figure out what module those are in support of, or what exported functions I would call to check against the list of trusted IPs. I have had a high fever for 2 days, so perhaps my brain is fried and I am missing something totally obvious :) Thanks! Geoff

[Kamailio-Users] Select a 3XX branch inmediatelly and CANCEL a ringing branch
by Iñaki Baz Castillo 18 Mar '09

18 Mar '09

Hi, let's me explain a simple escenario and the behaviour I want: Kamailio phone1 phone2-1 phone2-2 phone3 (201) (202) (202) (203) 1) 201 calls 202 so both phone2-1 and phone2-2 start ringing (180) in parallel. 2) phone2-1 replies a redirect "302" to user 203. 3) Kamailio cancels the branch with phone2-1 and replies 302 upstream *inmediatelly*. This is however not the most "compliant" behaviour, since Kamailio should wait for phone2-1 to reply a final response and then choose which one response to reply upstream. And that is of course the default behaviour in Kamailio. Is it possible however the behaviour I want? I find no way to get it. Thanks. -- Iñaki Baz Castillo <ibc(a)aliax.net>

I need to strip from $rU the lenght of $avp(CLIENT), this is: # Original $rU => client_xxx2004 strip($avp(CLIENT)); # New $rU => 2004 Unfortunatelly "strip()" doesn't accept a PV as parameter, but a static integer.

Re: [Kamailio-Users] Using Asterisk as media server
by Juan Perez 18 Mar '09

18 Mar '09

Alex, I understand your point and appreciate your input highly, but let's say that asterisk is needed as the media server for other reasons. It may not scale as well as the other solutions but we need them to be there to provide other services. I just wanted to know whether there was any difference aside from the scalabilty issue. We were under the impression that it was imperative to use either media-proxy or rtp-proxy but after examining in more detail how the 2 solutions work we find no reason not to use asterisk as the media proxy as well. Unless of course we are missing the big picture here and surely will find out once we set out to test it. But given the deep knowledge of a lot of people in this forum we deemed necessary to ask about the feasibility of this workaround. If somebody detects any flaw on this solution or if there is someting else critical or not that we are missing we would love to hear it . thank you in advance and thank you Alex again, jp ----- Original Message ---- From: Alex Balashov <abalashov(a)evaristesys.com> To: Juan Perez <jperezsip2008(a)yahoo.com> Sent: Monday, March 16, 2009 6:51:34 PM Subject: Re: [Kamailio-Users] Using Asterisk as media server No, because the amount of throughput you get per media/RTP proxy is much higher than you would get through something whose entire core is structured to behave as a PBX, with all the attendant features and latent event loop characteristics. A media relay does one thing and one thing only, and it does it well. Asterisk does many things, among them media relay. So, while you could use Asterisk in this capacity, I don't see the point. It'd be a waste of time. Also, you don't really want to get Asterisk involved in the signaling layer (as a B2BUA) if you can help it. It introduces unnecessary complexity and possible points of interop problems and failure. With a media relay that is controlled by API hooks into Kamailio, you don't have that problem.

[Serusers] Record-Route issues
by Stephen Helfen 17 Mar '09

17 Mar '09

I have a 0.9.6 SER proxy running and one particular UA that is creating some problems with a RECORD-ROUTE header I am not handling correctly. Here is how I have my record_route configured (XXXs are replaced by my actual proxy IP): if (!(uri=~^"sip:XXX.XXX.XXX.XXX")) { record_route_preset("XXX.XXX.XXX.XXX:5060;nat=yes"); }; When inbound traffic arrives for this particular UA, the INVITE is passed along. when the 200 OK comes back, there is a Record-Route header that looks like this (YYYs are replaced with the UA's public IP): RECORD-ROUTE: <sip:YYY.YYY.YYY.YYY:5060;lr;transport=udp> Instead of adding a new Record-Route header with my IP before this one, the message is simply proxied back to the call origination. The ACK is then sent DIRECTLY to the UA, bipassing my proxy...as well as the BYE/200 OK that terminates the call....thus rendering my stateful proxy as stateless. Can I remove the RECORD-ROUTE that my terminating UA is attaching? If not, why am I not adding my own Record-Route header like normal? What am I missing?

[Kamailio-Users] 487 Request Terminated and BYE
by Guillaume Lacroix 17 Mar '09

17 Mar '09

Hi, I am facing problem with handling CANCEL/487 Request Terminated in a case of a call hunting. The problem is that the call terminating carrier doesn't process the ACK properly and keeps sending 487 messages. Here is an example. Let's say UAC1 has the following rules of call hunting : 1. call +33123456 for 10s 2. call +33789456 for 10s Let's say that an incoming call to UAC1 triggers the call hunting. Here is a diagram : openSER -> Terminating Carrier (TC) : INVITE +33123456 ... (time out : +33123456 didn't answer in 10s, so openSER sends an INVITE to +33789456 - and let's say to an other Terminating carrier TC2 - and CANCEL the current INVITE to TC) openSER -> TC2 : INVITE : +33789456 openSER -> TC : CANCEL TC -> openSER : 487 Request Terminated openSER -> TC : ACK The problem is now TC doesn't process the ACK correctly and keeps sending 487. So, in the case of +33789456 answering the call (a 200 OK is sent to openSER), openSER will keep relaying the 487 to TC2 and TC2 will then send a BYE a terminate the call : TC -> openSER : 487 openSER -> TC : ACK TC -> openSER : 487 openSER -> TC : ACK TC2 -> openSER : OK openSER -> TC2 : ACK <-- The call is taking place --> TC -> openSER : 487 openSER -> TC : ACK openser -> TC2 : 487 (openSER relays the 487 once the call has been established to TC2) TC2 -> openSER : ACK TC2 -> openSER : BYE <-- Call is ended but should not --> According to the RFC, once a call has been OKed and a 487 is received, TC2 may go on with the call or send a BYE (up to it). So it behaves the right way (chapter 15. end of 3rd paragraph : "If the INVITE results in 2xx final response(s) to the INVITE, this means that a UAS accepted the invitation while the CANCEL was in progress. The UAC MAY continue with the sessions established by any 2xx responses, or MAY terminate them with BYE."). My question is then : is there a way to prevent this behavior when a terminating carrier doesn't behave correctly, either by preventing relaying of the 487 once it has been ACKed or once the call has been OKed (but I guess we are not RFC compliant then) ? Thanks Bye, Guillaume

[Kamailio-Users] Build for debug

Hello, sometimes when I'm investigating problems in my cfg files i think it could be easier to understand them if i could put some breakpoints on a gdb session. I don't grok makefiles yet. But I suppose there would be a command line option for the kamailio Makefile to instruct it to build the core and modules with debug symbols. So, how do you guys usually compile kamailio with debug symbols? regards, takeshi.

[Kamailio-Users] Handling of REGISTER messages when Kamilio is in front of Asterisk
by Juan Perez 16 Mar '09

16 Mar '09

Hello We are implementing an architecture with Kamailio and Asterisk with real time and are debating who should be the Registrar for the SIP clients. We are biased towards leaving that to Kamailio and use Asterisk to provide the media services: vmail, conference etc. It looks like this is the recommended way as per several tutorials on the net suggest that solution. As a down side we will have to use a combination of near-end [STUN, ALG] and far-end Nat solutions [rtp-proxy] to handle the media and also are kind of worried about how we should handle the Cass 5 features tipical of a residential line. But a member of our team suggests to use Asterisk for that and have Kamailio forwarding the REGISTER request from the clients to the Asterisk. Asterisk can handle media and also users behind a NAT. We have never done it that way and we are not sure whether it is possible or not, whether it is acceptable SIP-wise or not. For example: if the proxy is load balancing the REGISTER messages then the clients should be given the IP of the proxy to send the REGISTERs and the NAT binding in the customer's NAT/Firewall will be associated to the IP of the proxy, not the IP of the Asterisk. On then other hand, Asterisk as a PBX supports a lot of Class 5 features natively. We would like to hear your input, suggestions and comments about this, what other people are doing. If we had only a few user then 1 Asterisk box should be enough but we are planning on having way more that what an Asterisk machine alone can handle, that is why we want to load balance using kamailio. regards jp

[Kamailio-Users] Using fr_inv_timer_avp
by mayamatakeshi 16 Mar '09

16 Mar '09

Hello, I'm seeing the following issues when using the latest kamailio 1.4 (Revision: 5689) to set an AVP to control fr_inv_timer: - if I set the AVP to an empty string, according to tm doc, the value of the timer would fall back to the default value. This doesn't happen and the fr_inv_timer is set to zero (not a problem as I just have to set it to the static value. It is just inconsistent with the doc). - if I try to set the timer to something bigger than 60 seconds, the setting doesn't work and it seems the default value is used instead (I tested this with both hard-coding the assignment in the cfg and loading the avp from the usr_preferences). regards, takeshi

HI, Ive tested the LDAP authentication using Kamailio 1.4.2 and it works great. However, I'd like prevent the passwords being sent back "in the clear" from the LDAP server. Is there a way to use the Kamailio ldap module with TLS/SSL? I already have openssl and openldap-client on the kamailio box and can successfully use the ldapsearch command line tool via TLS.

Hi, "476 Unresolvable destination" is returned by Kamailio when the destination domain has no resolution. Is it a custom reply code? is it part of some RFC/draft? Thanks. -- Iñaki Baz Castillo

[Serusers] Questions about strip() and altering ANI/From: numbers
by Frank Durda IV 13 Mar '09

13 Mar '09

When using strip() on a E.164 format number (eg +17895551212), does strip(2) delete the +1, or is it going to delete "17" in the shown example? I seem to be getting the latter behavior. If the latter is what is intended, how does one get rid of the plus? Second, is there something equivalent to strip() for editing the ANI/From: number? As I am doing PSTN gateway conversions, I have to strip the +1 from a E.164 ANI/From: (if sent) at some point so that the destination PSTN switch can correctly do the Calling Name database lookup. The North American Calling Name databases will only match if exactly ten digits are provided, so the ANI/From: has to be scrubbed down to ten digits if the country code in the ANI/From: begins with +1. Thanks!

[Kamailio-Users] lcr-module, ping and load_gws_from_grp (kamailio 1.5)
by Stefan Prelle 12 Mar '09

12 Mar '09

Hi, I just noticed something weird when working with the lcr module. My setup has 5 gateways - 4 in group 1, one in group 2. The lcr-table has an entry for each group, both reacting on the same prefix. I am using load_gws_from_grp("1") to get a gateway for a target. This usually works fine. If now all 4 gateways in group 1 ar disabled because the alive check failed, load_gws_from_grp("1") returns the gateway from group 2 (or other groups where the prefix from the lcr-table matches. I would consider this a bug, since I explicitly requested gateways from a specific group. Regards, Stefan

[Serusers] Problem with Record-Route not being added
by Frank Durda IV 12 Mar '09

12 Mar '09

I have recently noticed that despite having a $record_route_nated = true; in the route[PSTN_FORWARD] of ser.cfg, the INVITES and such sent on do not have a Record-Route header. In our NATed situation, probably the only thing this would cause problems with would be when the called party hangs up first, SER and the calling party never find out about it, since the calling party IP is not reachable from the PSTN switch NATed address space, so the single BYE message sent by the PSTN switch probably whizzes by to an unreachable destination address. So the calling party remains off-hook and just gets dead air. When the calling party finally disconnects, the SER passes the caller-initiated BYE to the PSTN switch which returns a 481 because it thinks the call was over ages earlier. Or at least this is what appears to be happening. Here is the PSTN_FORWARD in use, not that different from the PSTN gateway example ser.cfg: route[PSTN_FORWARD] { # Set where packets should be sent. If you don't do this here, # OPTIONS and other messages will be transmitted back to the # outside interface and processed all over again, and you eventually # get a Too Many Hops error on every OPTIONS message. # Code to make this point in multiple directions would be needed # to implement two-way origination. rewritehost("10.x.x.x"); #Send to SIP-TDM switch if (method == "BYE" || method == "CANCEL") { unforce_rtp_proxy(); } else if (method == "INVITE") { # Force record routing if either party is behind NAT $record_route_nated = true; # log(1, "NAT Mangle Force RTP Proxy\n"); force_rtp_proxy("e"); } t_on_reply("PSTN_REPLY"); # if this is called from the failure route we need to open a new branch if (isflagset(FLAG_FAILUREROUTE)) { append_branch(); } # if this is an initial INVITE (without a To-tag) we might try another # (forwarding or voicemail) target after receiving an error if (method=="INVITE" && @to.tag=="") { t_on_failure("FAILURE_ROUTE"); } # send it out now; use stateful forwarding as it works reliably # even for UDP2TCP if (!t_relay()) { sl_reply_error(); } drop; } The resulting INVITE that is being sent on to the PSTN switch looks like: INVITE sip:+1xxxxxxxxxx@10.x.x.x:5060;npdi=yes SIP/2.0 Via: SIP/2.0/UDP 10.x.x.x;branch=z9hG4bK6804.1cb4cb23.0 Via: SIP/2.0/UDP 10.x.x.x:5060;branch=z9hG4bK1kpu0b20e0fgogk9c6d0.1 f: <sip:+1xxxxxxxxxx;jip=xxxxxx@10.x.x.x:5060;user=phone>;tag=d0a-13c4-83e003-64bd22fa-83e003 t: <sip:+1xxxxxxxxxx@10.x.x.x:5060;user=phone> i: a249e890d8184d0a13c483e0033230d1ff3b57654c1d4018-0143-8166 CSeq: 1 INVITE User-agent: CS2000_NGSS/9.0 P-Asserted-Identity: <sip:+1xxxxxxxxxx;jip=xxxxxx@10.x.x.x;user=phone> Max-Forwards: 16 k: 100rel Allow: ACK,BYE,CANCEL,INVITE,OPTIONS,INFO,SUBSCRIBE,REFER,NOTIFY,PRACK m: <sip:10.x.x.x:5060;transport=udp> c: application/SDP l: 231 v=0 o=- 15109843 15109843 IN IP4 10.x.x.x s=- c=IN IP4 10.x.x.x t=0 0 m=audio 44464 RTP/AVP 0 101 b=AS:80 a=ptime:20 a=rtpmap:0 PCMU/8000/1 a=rtpmap:101 telephone-event/8000/1 a=fmtp:101 0-15 a=nortpproxy:yes So, any ideas as to why the "$record_route_nated = true" doesn't seem to be having any effect, eg no Record-Route shows up in outbound messages? I know SER is passing through the above code because I can uncomment the "NAT Mangle" comment and see it in the logs. Is there perhaps some module that must be present that we may have eliminated that makes Record-Route get emitted? Thanks again!

[Kamailio-Users] SQLOps Module
by Andreas Heise 12 Mar '09

12 Mar '09

Hi, first of all thanks for the great sqlops module. Is "|sql_result_free(result)|" needed before I leave the script by "exit;" to avoid memory trouble or is it only needed to query again in the same request processing? Is there any way to check if the query was not successful (db unreachable, systax error in query)? I've seen a warning in the syslog, but I need to check it in the script. BTW in the doc the example for 1.4.2. seems to be wrong? regards, Andreas

[Kamailio-Users] Modifying the URI in the header From more than once
by mayamatakeshi 12 Mar '09

12 Mar '09

Hello, I'm trying to add CallForwarding to my kamailio.cfg. Before relaying an INVITE from one subscriber to another, I'm required to modify the From username to the PSTN number of the caller. So I use uac_replace_from and this works fine. I can see kamailio sendind this record-route: Record-Route: <sip:192.168.33.2;lr=on;ftag=qunug47bd1hc74ir26iv;vsf=AAAAAERUW1NLXloEeFVZKRYIDAZKBwRPEQYEH1oLCQAEFS5qcA--;did=b76.5c17ed25> But then, when the callee fails to answer and failure_route is called, I need to modify the From username to the PSTN number of the callee before doing the forward. If I simply try to call uac_replace_from again inside failure_route, record-route is sent with a duplicate vsf parameter like this: Record-Route: <sip:192.168.33.2;lr=on;ftag=qunug47bd1hc74ir26iv;vsf=AAAAAERUW1NLXloEeFVZKRYIDAZKBwRPEQYEH1oLCQAEFS5qcA--;did=b76.5c17ed25;vsf=AAAAAERUW1NLXloEeFVeKRYIDAZKBwRPEQYEH1oLCQAEFS5qcA--> And this causes two problems: - the message becomes too big and the GW replies with "513 Message too large" - the reply is sent back to the caller with duplicate From header and some UAs do not acknowledge the reply. So, is it possible to modify the From header more than once? regards, takeshi

Works simultaneous for IPv4 and IPv6 addresses. The module does not implement any actions on blocking - it just simply reports that there is a high traffic from an IP; what to do, is the administator decision (via scripting). ///////////////////////////////////////////////////////////////////////////////////////////////////////////////////// I understand from the first part that it blocks the IPs, but last sentence says otherwise.

[Kamailio-Users] Announcement Server
by Bruno Rodrigues 11 Mar '09

11 Mar '09

Hi All, First, sorry I have a bad english. Second, Anybody know if is possible redirect the call to one MediaServer when the destination answer the call? In the Media Server, the callee will hear a announcement, and the destination will hear a another announcement. The announcement has the same duration. When the announcement finish, the RTP will be established between the UA1 and UA2 The signaling I think will be this UA1 Kamailio UA2 Media Server Invite -----------------> - Received a normal Invite Invite----------------> - Forward The Invite <------------------200 - Receive the 200 OK <------------------200 - Forward the 200 OK <-------------re-Invite re-Invite ------------> - Kamailio will update the media part to the Media Server <----RTP Announce 1-----> - RTP are established <----------------------RTP Announce 2 ---------------------------------> - RTP are established <-------------re-Invite re-Invite ------------> - Kamailio after the announcement are finished update the Media part to UA1 ip media and UA2 ip media <-----------------RTP-------------------------> - RTP between UA1 and UA2 If have another way to do this, please let me know Thank You in advanced Bruno Rodrigues

If it is down dialog module (in db mode) can't work properly: In the log I see: after 200 OK to INVITE CRITICAL:dialog:log_next_state_dlg: bogus event 6 in state 2 for dlg 0xb61c0918 [360:515907930] with clid 'B8108B3CEBD9B8E3E1CC23DE8361D35F@sipsvr' and tags 'C319BA6F3E777E04867202774CE6443B' '' after BYE CRITICAL:dialog:log_next_state_dlg: bogus event 7 in state 2 for dlg 0xb61c0918 [360:515907930] with clid 'B8108B3CEBD9B8E3E1CC23DE8361D35F@sipsvr' and tags 'C319BA6F3E777E04867202774CE6443B' '' and no record is written in the dialog table. All come back to work after starting RADIUS server. This is not the main problem... In some circumstance kamailio fails to route properly the calls, due retransmissions; for instance after the client answers I see a lot of 200 OK sent to kamailio because it doesn't send the ACK immediately. In the log I see for each 200 OK: ... Mar 9 11:34:01 [27466] DBG:tm:timer_routine: timer routine:3,tl=0xb61a8ecc next=(nil), timeout=75 Mar 9 11:34:01 [27466] DBG:tm:delete_handler: removing 0xb61a8e68 Mar 9 11:34:01 [27466] DBG:tm:delete_cell: delete_cell 0xb61a8e68: can't delete -- still reffed (1) Mar 9 11:34:01 [27466] DBG:tm:set_timer: relative timeout is 2 Mar 9 11:34:01 [27466] DBG:tm:insert_timer_unsafe: [3]: 0xb61a8ecc (77) Mar 9 11:34:01 [27466] DBG:tm:delete_handler: done ... I was not able to replicate this problem. Solved after starting RADIUS server, but the problem doesn't occur if I stop it. I'm using kamailio 1.4.3, but the last problem occurred also on a production system with openser 1.2.3. After customer's RADIUS server went down, openser wasn't able to route all calls. Thank you very much for support. Regards, Antonio.

[Kamailio-Users] sl README does not know send_reply()
by jh＠tutpro.com 11 Mar '09

11 Mar '09

the new send_reply() function is not documented in sl/README. another related thing: would it be logical to also have corresponding reply_error() function especially when t_relay seems to create transaction even in case of some internal errors. -- juha

[Kamailio-Users] Problem starting Kamailio
by Sara EL KABIRI 11 Mar '09

11 Mar '09

Hello, I've installed kamailio 1.4.3 (without tls) on ubuntu by following the provided INSTALL guide. I want to use it as a presence server but i've got some problems starting it. "kamctl start" returns nothing. and "kamctl moni" returns "Error opening kamailio's FIFO /tmp/kamailio_fifo" I've checked in my .cfg file and the 'loadmodule' and 'modparam' lines related to mi-fifo module are uncommented. I've checked also the mi-fifo module was installed indeed (mi_fifo.so appears in /usr/local/lib/kamailio/modules directory). Could anyone help please? -- Sara

[Kamailio-Users] Force rtp proxy
by michel freiha 11 Mar '09

11 Mar '09

Hi all, I have a question regarding rtp proxy...I need to force rtp proxy in order that all rtp packets pass through...The issue now is the first INVITE does contains the PSTN GW IP instead of RTP Proxy IP...My config is as below: if (is_method("INVITE")) { # setflag(4); # do accounting fix_nated_sdp("1"); } if(!cr_route("default", "0", "$rU", "$rU", "call_id")){ sl_send_reply("403", "Not allowed"); } else { # In cas of failure, re-route the request t_on_failure("1"); t_on_reply("1"); force_rtp_proxy(); t_relay(); } onreply_route[1] { # if (t_check_status("2[0-9][0-9]") ) if((t_check_status("200|183|180") && search("Content_Type: application/sdp")) || search("Content-Type: application/sdp")) { force_rtp_proxy(); } exit; } Please let me know what's wrong here and how i can fix this issue Regards

Hello, is there any risk of having resources leaking if I fail to call unforce_rtp_proxy? Like having rtpproxy not freeing ports? I'm mean, my cfg is becoming bigger and I may fail to call this function somewhere. Should I be extremely careful about this? regards, takeshi

[Kamailio-Users] LCR With 300,000 Routes
by Geoffrey Mina 10 Mar '09

10 Mar '09

I have spec'd out how my LCR table would look based my current PSTN gateway providers. Looks like I would need to load roughly 300,000 routes to properly represent everything. This server needs to be able to support spikes of 100 call setups per second. What is the general consensus on this? And, if it's a No-Go, what alternatives do I have? I have looked briefly at the CarrierRoute module, but haven't actually played with it. Thanks! Geoff

Re: [Kamailio-Users] handling of DNS-SRV in kamailio-1.4.3 & 1.5.0
by Klaus Feichtinger 10 Mar '09

10 Mar '09

Hello Daniel, I've done several test with different scenarios: 1) including 4 hosts in the answer of the SRV reply message; the 1st and 2nd host are unreachable, the third an fourth are reachable - the SIP message never reached the target (= host 3) 2) including 4 hosts in the answer of the SRV reply message; the SIP service is not running on the first and second host; the third and fourth have the service activated - the SIP message is transmitted to the second host after the fr_timeout of the TM module, but is not forwarded to the target (= host 3); it is retransmitted to host 2 until SIP timeout The conclusion is: when only on master and slave are in the answer of the SRV reply message it works fine. But starting with the third host the service hangs on the second host and does not try reaching an alternative target (as listed in the SRV response). In the syslog I can only see entries like this (but no ERROR message): Mar 9 15:36:21 lennysrv /usr/local/sbin/kamailio[25041]: DBG:core:mk_proxy: doing DNS lookup...

[Kamailio-Users] t_relay with result code -6 creates transaction
by jh＠tutpro.com 10 Mar '09

10 Mar '09

i was playing with t_relay and tcp and noticed that when forwarding to a tcp contact fails, transaction is still created although README says: * 0x02 - do not internally send a negative reply in case of forward failure (due internal error, bad RURI, bad message, etc). When a forward failure occurs, no SIP request is relayed and therefore no negative reply or timeout will show up on the failure_route (if one is set). It applies only when the transaction is created. By default one negative reply is sent. Useful if you want to implement a serial forking in case of failure. and In case of error, the function returns the following codes: ... * -6 - generic send failed while testing this i had two contacts with different q values: Mar 10 06:50:07 taimen /usr/sbin/kamailio[18101]: DBG:tm:t_load_contacts: loaded contact <sip:test@192.98.101.10:5074#012#012#012udp:192.98.101.10:5060#0120#012d> with q_flag <0> Mar 10 06:50:07 taimen /usr/sbin/kamailio[18101]: DBG:tm:t_load_contacts: loaded contact <sip:jh@192.98.101.10:5555;transport=tcp#012#012#012#01216#0124> with q_flag <4> i then called next_contacts() followed by t_relay("0x03") and tested the result: while (1) { xlog("L_INFO", "INFO: Routing initial $rm to <$ru> and <$bR>\n"); t_relay("0x03"); switch ($retcode) { case 1: xlog("L_INFO", "INFO: retcode is <1>\n"); exit; case -1: case -2: case -3: sl_reply_error(); exit; case -4: xlog("L_INFO", "INFO: retcode is <-4>\n"); case -5: xlog("L_INFO", "INFO: retcode is <-5>\n"); case -6: xlog("L_INFO", "INFO: retcode is <-6>\n"); if (!t_next_contacts()) { send_reply("480", "Temporarily Unavailable"); exit; }; }; }; i got to syslog: Mar 10 06:50:07 taimen /usr/sbin/kamailio[18101]: DBG:tm:t_next_contacts: entering next_contacts WITHOUT transaction Mar 10 06:50:07 taimen /usr/sbin/kamailio[18101]: DBG:tm:t_next_contacts: R-URI contact is <sip:jh@192.98.101.10:5555;transport=tcp#012#012#012#01216#0124> Mar 10 06:50:07 taimen /usr/sbin/kamailio[18101]: INFO: Routing initial INVITE to <sip:jh@192.98.101.10:5555;transport=tcp> and <<null>> Mar 10 06:50:07 taimen /usr/sbin/kamailio[18101]: ERROR:core:tcp_blocking_connect: poll error: flags 18 Mar 10 06:50:07 taimen /usr/sbin/kamailio[18101]: ERROR:core:tcp_blocking_connect: failed to retrieve SO_ERROR (111) Connection refused Mar 10 06:50:07 taimen /usr/sbin/kamailio[18101]: ERROR:core:tcpconn_connect: tcp_blocking_connect failed Mar 10 06:50:07 taimen /usr/sbin/kamailio[18101]: ERROR:core:tcp_send: connect failed Mar 10 06:50:07 taimen /usr/sbin/kamailio[18101]: ERROR:tm:msg_send: tcp_send failed Mar 10 06:50:07 taimen /usr/sbin/kamailio[18101]: ERROR:tm:t_forward_nonack: sending request failed Mar 10 06:50:07 taimen /usr/sbin/kamailio[18101]: INFO: retcode is <-6> the first debug line above is a new one that i added to the beginning of next_contacts(): t = get_t(); if (!t || (t == T_UNDEFINED)) { LM_DBG("entering next_contacts WITHOUT transaction\n"); } else { LM_DBG("entering next_contacts WITH transaction\n"); } then the script goes on and calls t_next_contacts()/t_relay("0x03") again and now i get: Mar 10 06:50:07 taimen /usr/sbin/kamailio[18101]: DBG:tm:t_next_contacts: entering next_contacts WITH transaction Mar 10 06:50:07 taimen /usr/sbin/kamailio[18101]: DBG:tm:t_next_contacts: next branch contact is <sip:test@192.98.101.10:5074#012#012#012udp:192.98.101.10:5060#0120#012d> Mar 10 06:50:07 taimen /usr/sbin/kamailio[18101]: INFO: Routing initial INVITE to <sip:jh@192.98.101.10:5555;transport=tcp> and <<sip:test@192.98.101.10:5074>;q=0> Mar 10 06:50:07 taimen /usr/sbin/kamailio[18101]: INFO: retcode is <1> how is it possible that the transaction was created even when the first t_relay failed with result code -6? this example should prove that scripting tm like this NOT user friendly and prone to errors. -- juha ps. i think we agreed earlier that failing forward to a tcp contact is NOT an error and should not be printed to syslog as an error.

[Kamailio-Users] lcr-module, ping and load_gws_from_grp (kamailio 1.5)
by Stefan Prelle 09 Mar '09

09 Mar '09

Hi, I just noticed something weird when working with the lcr module. My setup has 5 gateways - 4 in group 1, one in group 2. The lcr-table has an entry for each group, both reacting on the same prefix. I am using load_gws_from_grp("1") to get a gateway for a target. This usually works fine. If now all 4 gateways in group 1 ar disabled because the alive check failed, load_gws_from_grp("1") returns the gateway from group 2 (or other groups where the prefix from the lcr-table matches. I would consider this a bug, since I explicitly requested gateways from a specific group. Regards, Stefan

[Kamailio-Users] Send a status from reply route
by Kévin L'heveder 09 Mar '09

09 Mar '09

Hi, I work with Kamailio as Proxy and a call manager. From a MI_datagram script I manage kamailio. My script check the current data rate on different links. So if the max data rate is reached my script must cancel the call. That works good because I can use t_reply or sl_send_reply from request route and send cancel or status error. But in one case I need to cancel the call after receiving the trying (after INIVTE) from the call manager (because the call manager could preempt a call to free some space one the link) My trouble is that i can't use t_reply or sl_send _reply from REPLY_ROUTE and to cancel the call properly i need to send a status error, so i can't use t_uac_dlg from my management interface (because this function sends request only). I didn't find out a solution to do this, so is someone have one ...?

[Kamailio-Users] reseting of t_on_branch, t_on_reply and t_on_failure

i have noticed that i need to call again t_on_branch, t_on_reply and t_on_failure in failure route before calling again t_relay, i.e., successful call of t_relay resets these settings and they need to be re-armed. how about if t_relay fails and transaction is not created? are the t_on_X calls still in effect or do they need to be re-armed again? i haven't found in tm/README any discussion about when the t_on_X calls get reset. -- juha

[Kamailio-Users] SIP Re-Routing using Private Header
by Geoffrey Mina 08 Mar '09

08 Mar '09

Hello, I have a problem which I am not sure the best way to solve with Kamailio. I have many asterisk servers which use Kamailio as their outbound gateway to route calls to the PSTN. This works great, I use the LCR engine to control routing. What I want to do is have the ability to dial a random SIP URI from my asterisk servers, but route the call through my Kamailio server for accounting and security purposes. My asterisk servers are not allowed SIP messaging from anything other than my Kamailio gateway. What I am considering doing is something like this: Since asterisk is fairly limited in your ability to route calls, I need to do a little magic to make the call route through a proxy. Maybe I'm wrong, but I haven't yet been able to figure it out. My theory is that I will add a special header at the asterisk level and send the invite to Kamailio. [test] exten => 1,1,SipAddHeader("P-Forward-URI: bob(a)somedomain.com") exten => 1,n,Dial(SIP/forward@kamailio,30) [From Asterisk To Kamailio] INVITE sip:forward@10.1.1.1 SIP/2.0 Via: SIP/2.0/UDP pc33.atlanta.com;branch=z9hG4bK776asdhds Max-Forwards: 70 To: <sip:forward@10.1.1.1> From: "" <sip:5555551212@pc33.atlanta.com>;tag=1928301774 Call-ID: a84b4c76e66710(a)pc33.atlanta.com CSeq: 314159 INVITE Contact: <sip:5555551212@pc33.atlanta.com> Content-Type: application/sdp Content-Length: 142 P-Forward-URL: bob(a)somedomain.com if(is_present_hf("P-Forward-URL")){ //what do i do here to rewrite the To and INVITE parts before doing record_route() and t_relay() } Maybe I'm totally off track here, but this is all I have come up with so far! Perhaps there is a mechanism in SIP which already allows me to do this, and I don't know about it... I don't know what I don't know :) Thanks, Geoff

[Kamailio-Users] compile problem on debian lenny

Dear all, I tried to compile trunk version on debian lenny, but it failed. flex, bison and so on are installed.

[Kamailio-Users] Need help terminating inbound and outbound calls from PSTN!!!!
by carl Lougher 07 Mar '09

07 Mar '09

Hi, I finally managed to get outbound calls working to the PSTN but am struggling with the inbound ones. Current setup: Kamailio 1.5 Sip trunk to Trixbox using username and password stored in Kamailio db PSTN - Gateway only using ip address and no auth. Questions: 1. Am i using the correct method for terminating outbound calls from the Trunk? Currently using rewritehostport off invite. 2. I've tried using allow trusted for the inbound calls from the PSTN GW but they do not connect to the sip trunk. Although i do see the call coming in using ngrep. 3. How do i pass multiple inbound calls to the trunk when it only has one number associated to it in the db? 4. Is there a better method for terminating calls in and out from asterisk/trixbox on sip trunks? cfg file: Last login: Sat Mar 7 14:25:33 2009 from 121-73-118-198.cable.telstraclear.net [root@zedd ~]# cat /usr/local/etc/kamailio/kam kamailio.cfg kamailio.cfg.working kamailio.cfg.working2 kamctlrc [root@zedd ~]# cat /usr/local/etc/kamailio/kamailio.cfg # # $Id: kamailio.cfg 5652 2009-03-02 11:13:38Z henningw $ # # Kamailio (OpenSER) SIP Server - basic configuration script # - web: http://www.kamailio.org # - svn: http://openser.svn.sourceforge.net/viewvc/openser/ # # Direct your questions about this file to: <users(a)lists.kamailio.org> # # Refer to the Core CookBook at http://www.kamailio.org/dokuwiki/doku.php # for an explanation of possible statements, functions and parameters. # # There are comments showing how to enable different features in th econfig # file.

[Kamailio-Users] LCR Documentation
by Geoffrey Mina 07 Mar '09

07 Mar '09

Hello, I am currently deploying the LCR module. I have some questions about fields and what they do... I searched the docs, but couldn't find anything. Can someone please fill in the blanks? [LCR Gateways] Gateway Name: description of the gateway Group ID: Numeric identifier used to link LCR Rules IP Address: The IP of the SIP gateway Hostname: The hostname of the SIP gateway (not required if IP provided?) Port: The port the SIP gateway listens on URI Scheme: (well documented) NULL = sip, 1 = sip and 2 = sips Transport: (well documented) NULL = none, 1 = udp, 2 = tcp, 3 = tls, and 4 = sctp Strip: ? Tag: ? Weight: ? Ping: ? Flags: ? [LCR Rules] Prefix: The matching prefix. In the US most would do this by area code, so I would assume I would put something like 1678 or 1770 to route Atlanta calls. Would putting a NULL or Empty String force a default route for everything? >From URI: If I don't care about the from URI can I leave this NULL or BLANK? Group ID: The numeric identifier matching to LCR Gateways Priority: I am assuming if there are 2 records which match the prefix and from URI the high priority will be chosen first? Also, say for example, one of my gateway providers has a primary and a secondary gateway. If the primary is down I need to route calls to the secondary. How would this fit into an LCR scheme? Would I need duplicate routes for the secondary with a lower priority? Thanks, Geoff p.s. for anyone holding out, I just installed Siremis today and it rocks! I am really quite pleased with the solution.

[Kamailio-Users] Normalising
by Brian Chamberlain 06 Mar '09

06 Mar '09

Hi List!, I am trying to write a normalised uri into the radius record for accounting reasons. I have a route[5] that does the transformation for me I translate the uri and store it in a variable. $var(translated_uri) = $ru; $ru = $var(ruri_store); In the accounting module parameters I store Sip-Translated-Request- URI= $var(translated_uri) = $ru; I added the following debug in my route[5] to check the variables are being transformed and they are as I want. xlog("L_INFO", "[TEMP1] Accounting translation: $ru\n"); xlog("L_INFO", "[TEMP2] Accounting translation: $var(translated_uri)\n"); The Sip-Translated-Request-URI is equal to 0 on the radius record.. What am I missing here? I hope I have explained myself well Thanks, Brian

[Kamailio-Users] Where to add pstn route to .cfg file?

06 Mar '09

Howdy, I'm getting a little further now but have got stuck at the pstn stage. Now if i delete all the current routes in the kamailio.cfg file and just add a rewritehostport then outbound calls work. Now where exactly do i add this in the .cfg file with all the other routes? I'm not concerned about groups or specfic patterns .* can get sent on. Also for the auth to Trixbox am i better to put as a trusted gw or leave as username/password macth in db?

[Kamailio-Users] t_uac_dlg syntax
by kévin l'heveder 06 Mar '09

06 Mar '09

Hi, Each time I try to use t_uac_dlg from a management script using MI_DATAGRAM (Kamailio v1.4), Kamailio answers "bad headers". I didn't find out some working examples, so i hope someone could help me. Here's what I send on my UDP socket: ":t_uac_dlg:\nCANCEL\nsip:154@192.168.10.250 <nsip%3A154(a)192.168.10.250>\n.\n.\nFrom: sip:655@192.168.10.250 <sip%3A655(a)192.168.10.250>\nTo: sip:154@192.168.10.250 <sip%3A154(a)192.168.10.250>\n" ( \n.\n. : because i don't specify next hop and the socket ; also i don't specify body) If someone could correct me or give me a working example, that would be very nice. Thanks, Koon

[Kamailio-Users] notls vs tls sources
by Luciano Afranllie 06 Mar '09

Hi everybody, May be this is a stupid question but I want to know what is the difference between kamailio-1.x.0-notls_src.tar.gz and kamailio-1.x.0-tls_src.tar.gz I guess it is tls support but INSTALL file of notls version talks about compile with TLS support, that is why I am asking... ... - compile with TLS or SCTP support make TLS=1 make SCTP=1 Thanks Luciano

[Kamailio-Users] handling of DNS-SRV in kamailio-1.4.3 & 1.5.0
by Klaus Feichtinger 06 Mar '09

06 Mar '09

Hello, I have to relay SIP requests to a special "redundant" destination (= FQDN - e.g. "test.kamailio.loc") that consists of 3 hosts with different priorities. After startup Kamailio creates a DNS-SRV request to the DNS server and receives a response with following answer (e.g.): _sip._udp.test.kamailio.loc: type SRV, class IN, priority 10, weight 100, port 5060, target host1.test.kamailio.loc _sip._udp.test.kamailio.loc: type SRV, class IN, priority 20, weight 90, port 5060, target host2.test.kamailio.loc _sip._udp.test.kamailio.loc: type SRV, class IN, priority 30, weight 80, port 5060, target host3.test.kamailio.loc In worst case - if the prime and secondary host (host1 and host2) are unavailable - I expect that kamailio tries relaying the request to the third host in the list. But it doesn't. It makes retransmission of the original invite to the second host and does not try reaching the third host. For tuning the switchover to the alternative target(2) I have set the module parameter "fr_timer" for TM to 3 seconds (modparam("tm", "fr_timer", 3)). Is this behaviour of Kamailio-1.4.3 and Kamailio-1.5.0 (I've tested it with both versions) as expected (= limited to support only two answers in a DNS SRV reply)? Does anybody have experience with this scenario? Can anybody give me a hint? regards, Klaus F. -- Computer Bild Tarifsieger!

Ha ha thanks guys. Who wants the 25cents? Ok i dont have an issue with Asterisk/Trixbox as i've been using that for years. I also dont have an issue with Kamailio installation. The issue i have though is that being a newbie to Kamailio i am struggling to understand and come up with a cfg file to allow the following. 1.To allow Kamailio to accept calls from a specific asterisk/trixbox (authentication would be best). 2.To forward all calls from Kamailio to the Sip provider (how do i set that up? No auth required for sip provider). 3.To apply rtp proxy or nathelper if required. 4.To send cdrs to a mysql database. I've had several attempts at writing stuff to the route part of the cfg file but it always fails to load. Is the best method to find the failure to use /var/log/messages? Thats about it and oh my amazon purchase of "Building Telphony systems with Openser" book turned up today so hopefully reading that might make a difference.

IIRC some devels in the past asked for conversion from svn to gitin kamailio (openser), but at that time SF didn't offer it.

Hi, I'm after some useful doco to allow me to setup trunks from Trixbox to Kamailio and push all calls to a sip provider. Would possibly need rtpproxy or nathelper as well. Can anyone point me in the right direction as i've been combing the web for days and unable to find anything with good explanations and basic enough for a Kamailio beginner. Thanks, Taff.

Hi gentlemen, I'm trying to find a suitable topology to deploy on our SIP network. We started testing UCARP, but it seems it's not going to do for us. Our topology involves 2 servers with physical IPs on them and 2 floating IPs (to balance load 50% on each). The balancing is manual, we are going to point half our servers (measured in load) to one floating IP and so on. When a server fails, the other will handle the load assuming the other floating IP. We found an issue managing IPs, if we have to make Kamailio listen to a floating IP we have to set: listen=0.0.0.0 and then record_route will just pass that IP on the record route headers, making destination servers not to respond. If we try to use record_route_preset() there, when server A fails, all responses come with the "wrong" IP on record_route when server B assumes A's IP. I'd like to know if some of you found a tidier solution and would like to share some topology and implementation tips. DNS SRV is also on our list, but maybe there is something out there that can help us with this. Thanks in advance, Uriel

[Kamailio-Users] How to send a to-tag in a CANCEL request generated by carrierroute?
by mayamatakeshi 04 Mar '09

04 Mar '09

Hello, I'm using the module carrierroute. I'm setting the carrierfailureroute table to try a second route if the first one times out. The first route is a GW that sends 183 Ringing with SDP and to-tag. But when the failure_route is called due to timeout and the second route is resolved I see kamailio sending a CANCEL without a to-tag and the GW replies with "481 Call Leg/Transaction Does No Exist". So, This fails to cancel the first request. How can I make kamailio send the to-tag in the CANCEL request? Also, I noticed kamailio sends the INVITE to the second route before sending the CANCEL to the first one. Was this coded on purpose? (I believe this doesn't go against the RFC, but it is something curious). If you bother to look at my cfg, here's the relevant parts: route { .........some stuff ..... DOMAIN_AVP = ""; if (!cr_route("CARRIER_AVP", "DOMAIN_AVP", "$rU", "$rU", "call_id", "HOST_AVP")) { sl_send_reply("404", "No Route"); exit; } t_on_failure("ROUTE_FIRST_ATTEMPT_FAILURE"); if (subst_uri('/(sip:.*);nat=yes/\1/')) { setbflag(NAT_BFLAG); } if (isbflagset(NAT_BFLAG)) { fix_nated_contact(); if (is_method("BYE|CANCEL")) { unforce_rtp_proxy(); } else if (is_method("INVITE")) { force_rtp_proxy("cfr"); } search_append('Contact:.*sip:[^>[:cntrl:]]*', ';nat=yes'); } t_on_reply("ONREPLY"); if (!t_relay()) { sl_reply_error(); } } failure_route[ROUTE_FIRST_ATTEMPT_FAILURE] { if (isbflagset(NAT_BFLAG)) { unforce_rtp_proxy(); } revert_uri(); if (!cr_next_domain("CARRIER_AVP", "DOMAIN_AVP", "$rU", "HOST_AVP", "$T_reply_code", "DOMAIN_AVP")) { exit; } if (!cr_route("CARRIER_AVP", "DOMAIN_AVP", "$rU", "$rU", "call_id", "HOST_AVP")) { exit; } t_on_failure("ROUTE_SECOND_ATTEMPT_FAILURE"); append_branch(); route(RELAY_REQUEST); } failure_route[ROUTE_SECOND_ATTEMPT_FAILURE] { if (isbflagset(NAT_BFLAG) ) { unforce_rtp_proxy(); } }

[Kamailio-Users] htable question
by Klaus Darilion 04 Mar '09

04 Mar '09

Hi! Sorry for not knowing how hash table works, thus my questions may be a bit stupid: How many items can be stored in hashtable? Is it limited to "size" parameter, e.g. 10 means max. 1024 entries? Or is it as much as memory is available (what for is the size parameter in this case)? How can I delete a key from htable? Example: I want to track concurrent calls (lets pretend there is no dialog module :-): # pseudo language if INVITE $sht(a=>$ci) = $ts; ... elseif BYE $avp(s:duration) = $ts - $avp(s:duration); # how to delete this key now from the htable? Is it possible to iterate over all entries in the htable? thanks klaus

[Kamailio-Users] Carrierrout issue
by Ali Jawad 03 Mar '09

03 Mar '09

Hi I do use carrieroute to balance calls to 3 servers and those 3 servers do use a2billing and they forward calls to my pstn gw. I do have a graph that has the active calls on them randomly and it does not depend on the load at hand the calls spike up on all 3 servers together. And most of those calls are in ringing state but with no callerID. Normally in the log for carrieroute I have something like this: Mar 3 13:39:10 [4288] INFO:carrierroute:cr_do_route: uri xxxxxxxxxxxxx was rewritten to sip:xxxxxxxxxxxxxx ACC: transaction answered: timestamp=1236087551;method=INVITE;from_tag=rMciw2o;to_tag=as7761f5cf;ca ll_id=c745983c;code=200;reason=OK ACC: request acknowledged: timestamp=1236087551;method=ACK;from_tag=rMciw2o;to_tag=as7761f5cf;call_ id=c745983c;code=200;reason=OK Mar 3 13:39:11 [4286] INFO:carrierroute:cr_do_route: uri xxxxxxxxxxxxx was rewritten to sip:xxxxxxxxxxxxxxx Mar 3 13:39:12 [4287] INFO:carrierroute:cr_do_route: uri xxxxxxxxxxxx was rewritten to sip:xxxxxxxxxxxxxx ACC: transaction answered: timestamp=1236087552;method=INVITE;from_tag=yJ+hSWA;to_tag=as26649b96;ca ll_id=a1c42904;code=183;reason=Session Progress ACC: transaction answered: timestamp=1236087552;method=INVITE;from_tag=CAJpAXg;to_tag=as5d24ff4f;ca ll_id=a35563d5;code=183;reason=Session Progress ACC: transaction answered: timestamp=1236087552;method=INVITE;from_tag=7i2kutG;to_tag=as6c125d0e;ca ll_id=2739b561;code=183;reason=Session Progress Mar 3 13:39:12 [4285] INFO:carrierroute:cr_do_route: uri xxxxxxxxxxxxxx was rewritten to sip:xxxxxxxxxxxxxxxxxx ACC: transaction answered: timestamp=1236087553;method=INVITE;from_tag=tMs9y8M;to_tag=as18b7f087;ca ll_id=7d65d34b;code=183;reason=Session Progress However when this problem happens the log screen only has the something like the below and as said the calls are in ringing state with no caller ID: Mar 3 13:39:11 [4286] INFO:carrierroute:cr_do_route: uri xxxxxxxxxxxxx was rewritten to sip:xxxxxxxxxxxxxxx Mar 3 13:39:12 [4287] INFO:carrierroute:cr_do_route: uri xxxxxxxxxxxx was rewritten to sip:xxxxxxxxxxxxxx

[Serusers] fix_nated_contact onreply
by samuel 02 Mar '09

02 Mar '09

I have seen lots of default config files where in the reply route only after checking the message (client_nat_test(1)) fix_nated is called. Why is not called when the NAT flag is set upong lookup_XX? In ser-oob I think the reply_route should include the case of a user called behind a NAT and the reply is not fixed due to some router in the middle. Will it hurt including fix_nated_contact in the case of checking the flag? Friday thoughts... Samuel

Re: [Kamailio-Users] how to know if my gw servers are active ?
by BERGANZ François 02 Mar '09

For the database, asterisk and SER work on the sameone. in sip.conf create one for SER and insecure=invite. It accept all from SER In the SER, configure the auth_db module to check the username col and password col. SER is a wall between client and asterisk(s). The same SER can be a wall between asterisk and provider. It is just a gymnastic! To test, it, the best is to have all in the same UC. And have one virtual networkInterface per Asterisk and SER.

I am trying to setup a solution for 2 Asterisk or more servers to allow dynamic and not static user registration. i.e. any user can register with any of the Asterisk servers. Let's say if UserA register with Asterisk1, this will reflect on SER's database where to route the call. In this scenario of UserA now register with Asterisk4 5 minutes later, SER's database will be automatically updated and calls to UserA will be automatically routed to Asterisk4.

[OpenSER-Users] [OT] How to handle different DID's in incoming calls for a registered client?
by Iñaki Baz Castillo 27 Feb '09

27 Feb '09

Hi, maybe this question is a bit off-topic so I'm sorry for that. My question is about SIP providers using OpenSer that associate PSTN numbers to their local clients (SIP accounts): Usually the client must register to OpenSer in order to receive calls. Then it will appear in location table with "Contact=sip:clientX@IP". Suppose clientX has two PSTN numbers associated in a ENUM entry: +34999000111 +34999000222 When anyone in PSTN world calls to +34999000222 the call will arrive to the OpenSer from a gateway in an INVITE like: INVITE sip:+34999000222@gateway SIP/2.0 To: <sip:+34999000222@gateway> The OpenSer will do the lookup in location table and finally send this INVITE to the clientX: INVITE sip:clientX@IP_clientX SIP/2.0 To: <sip:+34999000222@gateway> The info about the called PSTN number is just available in "To" header, so a way to get different behaviour for each associated PSTN number is matching "To" URI. Is common to do it? which other alternatives are there? Thanks for any comment. Regards. -- Iñaki Baz Castillo ibc(a)in.ilimit.es

According to the config, you do not even set the accounting flag for ACK, or I missed something there? Can you compile with memory debug turned on and test? Watch the syslog for critical errors. It can turn to be a buffer overflow somewhere. Once again, what is the version are you using?

[Kamailio-Users] Kamailio Newb questions
by carl Lougher 27 Feb '09

27 Feb '09

Howdy, I'm trying to remove the media/rtp streams from an asterisk server for natted users so would like to know if this is possible with kamailio. Qu's: What is the best option? rtpproxy/mediaproxy? nathelper? If i use kamailio to achieve this does it mean that i still have to carry the rtp streams through the kamailio server instead? Also will i need to change the logon info for the clients so they now logon to kamailio then i just point registrar to asterisk? Can i use kamailio for sip trunks to asterisk and carry rtp and natted clients media streams rather than register to asterisk? Many thanks, Taff..

[Kamailio-Users] default config file
by Elena-Ramona Modroiu 26 Feb '09

26 Feb '09

Hi, looking at the default config file, we deliver something pretty useless and very insecure. I propose to add to it several features so it becomes really usable: - mysql support - even some use radius for aaa, mysql is for sure used for usrloc. Those using other db drivers can just replace the module - auth against db and check auth username against from/to username to avoid spoofing - accounting - at least to syslog to store more than default data which gives nothing useful right now. Thinking to from/ruri username and domain at least in order to have caller and callee details - usrloc to database - nat traversal support with nathelper and rtpproxy - if rtpproxy is not running, will be just warnings at startup - the first part of the config will have some help of how to configure the environment to start the sip server (e.g., add user, ...) What do you think? Regards, Ramona

[Serusers] Need easiest way to set/clear a flag and refer to it later in same call session
by Frank Durda IV 26 Feb '09

26 Feb '09

I need a simple way to set either a boolean flag (or integer value) during the INVITE of a given call in ser.cfg, and test that value via "if" elsehere in ser.cfg during the 183/200 response messages for that same call. This would be a data object unique to a given call, which should disappear/lose persistence/end scope when a given call ends. Not global, no need to write the value to disk, doesn't need to survive a restart of SER, etc. The various SER documents describe a number of things that could do this, but most seem overly complex, storing the object in a MYSQL database on disk or something, and these all seem so excessive. There also appear to be a few built-in flags, but the documentation suggests that all are actually there for specific uses and so use for other things might not work. I simply want to make a determination of something during the INVITE for call 12345, and be able to refer to that flag or integer value later on when the various response messages for the same call (#12345) are coming back through. I can't make the same determination on each message after the INVITE because the original src_ip address value where the INVITE came from doesn't seem to be in a testable variable when handling reply messages, or at least not in one that is clearly documented. I've chased a number of possible ways this might be done, but tire of being referred away from the doc that came with the source and over to web sites that tell me this or that module that might do part of what I need is deprecated and to use this other module, but the web site for the other module says that the first module is better suited to what I want to do (a circle), doesn't show how the set value can actually be tested, or the web page just doesn't work anymore. So, assuming there is a simple way to do this, I need a quick code snip showing how to set/clear/assign a value to such a beast within INVITE handling, and a quick code snip of how to test it in an "if" statement during 183/200/110 type response messages. Whatever it is, the value set, cleared or being tested in one call should not affect any other call. Thanks in advance!

[Kamailio-Users] Handling CANCEL and 487
by Juan Perez 25 Feb '09

25 Feb '09

Hello I am having a prob handling the CANCEL in this scenario Kamailio 1.4 doing basic load balancing with LCR module. Calling party makes a call, sends it to Kamailio, Kamailio looks up the destination gw and sends the call to the dest IP. I am using statefull mode and loose routing. The calling party makes the call and while it is ringing it hangs up. Kamailio receives the CANCEL and forward it to the dest IP, it receives the 487 from dest IP and pass it back to the calling party. This is when it gets weird. The calling party sends the ACK to the 487 and it looks like the proxy [kamailio] ignores it and keep sending the 487 to the calling party. Calling party IP: 192.168.1.200 kamailio[proxy]: 192.168.1.50 dest IP: 192.168.11 PLease see below a tethereal output and my config file. I would appreciate any help to help me fix this prob.

Re: [Kamailio-Users] Need to handle an upstream carrier error - Duplicate INVITE Messages
by Geoffrey Mina 25 Feb '09

25 Feb '09

Hello, I have a carrier who provides PSTN gateway services. They have multiple redundant sip gateway devices in their network. The problem occurs when one of their devices starts to have issues. I will receive an INVITE request from both gateways with the same call-id. The problem is that my Kamailio system doesn't detect that I already set a call up for the INVITE once, and forwards the request to another server in the dispatcher list. What I end up with is a call on two asterisk servers, but only one has the actual RTP stream. The BYE request gets routed to the wrong server, and everything just gets screwy. If anyone could provide any hint on how I might be able to deal with this scenario, I would really appreciate it. I have attached my current config file, and the following is a link to a google spreadsheet which shows the SIP trace. http://spreadsheets.google.com/ccc?key=pU5i2J6Ck3b519-_M6Et3cw I have masked my IP addresses for my own sanity. XX.XX.XX.179 - Kamailio SIP Gateway XX.XX.XX.189 - Asterisk1 XX.XX.XX.186 - Asterisk2 Thanks! Geoff

[Kamailio-Users] openser not distributing to all DNS SRV entries
by Brian 25 Feb '09

25 Feb '09

Hi, I have a SRV setup with three equal priority entries and equal weights. I expected openser (version 1.3.3) to distribute the INVITE requests equally to all 3 hosts, but it seems that all requests are forwarded to only one host. The SRV entries look like this: _sip._udp.mydomain.com. 8805 IN SRV 100 33 5060 proxy1.mydomain.com. _sip._udp.mydomain.com. 8805 IN SRV 100 34 5060 proxy1.mydomain.com. _sip._udp.mydomain.com. 8805 IN SRV 100 33 5060 proxy1.mydomain.com. And my routing for INVITE request looks like this: rewritehost("mydomain.com"); rewriteport(""); if (!t_relay()) { sl_reply_error(); }; exit; Am I wrong in expecting this to distribute equally to the three proxy hosts? I thought this would just "work". Thanks, Brian.

[Serusers] Cleaning bad npdi=yes and rn=VALUE tags from INVITEs
by Frank Durda IV 24 Feb '09

24 Feb '09

I have a client who occasionally sends calls where there is a npdi=yes tag (and there may or may not be a rn=VALUE tag present with it), BUT the answer these two tags are providing is wrong! That is, the number in question has or hasn't been ported, but the information provided in the INVITE message doesn't match reality. Either a rn=VALUE should have had value X and it instead has value Y, OR there is no rn=VALUE at all, and there should have been one, OR the number hasn't actually been ported, and no rn=VALUE should have been sent at all but we got a junk one, that probably isn't the right LRN for the true destination of the call. Because of these wrong npdi=yes tags, our PSTN gateway switch ends up failing these incorrectly-marked call, because it takes the provided rn=VALUE or lack of one to be correct and so it doesn't do its own LNP query, and the one provided in the SIP INVITE is sometimes just flat out wrong. If the PSTN gateway switch had ignored these suspect npdi=yes and rn=VALUE tages and simply done the LNP query itself, in virtually all cases these otherwise doomed calls would have completed successfully. For this particular customer, the problem of bogus values appears to be a permanent artifact. They either don't know how to fix it, or don't think it is important, of they are spoofing it to avoid being billed for LNP queries. Whatever the reason, it causes trouble tickets. So, we would like to have SER strip the npdi=yes and any rn=VALUE tags from the INVITE when it is this customer (known by src ip), so that the PSTN switch will do the LNP query itself on the SS7 side and get the call routing right. (We have already determined that getting the outfit that is sending the junk to do the right thing isn't going to happen any time soon.) Does anybody have any suggestions as how to write the ser.cfg code to edit-out a npdi=yes and rn=VALUE if they are present in INVITEs? We just want to always throw npdi=yes and any rn=VALUE that shows up if the call is coming from this given customer, basically treating all npdi=yes and rn= tags coming from this customer as being untrustworthy. There has to be an easier way than stripping the thing down and reassembling a new one with repeated strip(1) type operations, which looks to be extremely inefficient for this task and probably really meant only for stripping country codes and such off the phone numbers, not for cleaning up bad tags. Thanks, in advance!

[Kamailio-Users] problem with 200ok
by BERGANZ François 23 Feb '09

23 Feb '09

Hello, I have Asterisk1---SER---Asterisk2. When I do INVITE from the left, --the asterisk2 send 200ok to the SER --the SER forward to the Asterisk1 --but the asterisk1 directly send the ACK to Asterisk2 Asterisk2 retransmit the 200ok… and error. I think that it need that the ACK come from the SER and not directly from the Asterisk1. So, how can I detect a 200ok and reply a ACK with my SER? Or, anyone have ever seen that problem?
