SIP UA's behind same NAT
by Deon Vermeulen 20 Dec '10

20 Dec '10

Hi List Can someone please help me? I need to implement PBX Services for a customer that has 10 IP Phones at his Main site and then 20 IP Phones located over 5 Branches. My goal is to have RTP go end to end and not proxied. I had a look at the below link and tried it, but with no luck. http://kamailio.org/dokuwiki/doku.php/examples:caller-callee-behind-same-nat Here is a partial output of my kamailio.cfg file if someone would be so kind to help me. #!ifdef WITH_NAT # ----- rtpproxy params ----- modparam("rtpproxy", "rtpproxy_sock", "udp:localhost:7722") # ----- nathelper params ----- modparam("nathelper", "natping_interval", 30) modparam("nathelper", "ping_nated_only", 1) modparam("nathelper", "sipping_bflag", FLB_NATSIPPING) modparam("nathelper", "sipping_from", "sip:pinger@x.x.x.x") # params needed for NAT traversal in other modules modparam("nathelper|registrar", "received_avp", "$avp(RECEIVED)") modparam("usrloc", "nat_bflag", FLB_NATB) #!endif ####### Routing Logic ######## # Main SIP request routing logic # - processing of any incoming SIP request starts with this route route { # per request initial checks route(REQINIT); # NAT detection route(NAT); # Caller NAT detection route route[NAT] { #!ifdef WITH_NAT force_rport(); if (nat_uac_test("19")) { if (method=="REGISTER") { fix_nated_register(); } else { fix_nated_contact(); } setflag(FLT_NATS); } #!endif return; } # RTPProxy control route[RTPPROXY] { #!ifdef WITH_NAT if (is_method("BYE")) { unforce_rtp_proxy(); } else if (is_method("INVITE")){ force_rtp_proxy(); } if (!has_totag()) add_rr_param(";nat=yes"); #!endif return; } Thank you in advance Kind Regards Deon

CRASH on qm_free for simultaneous calls (V3.1.0)
by Jijo 20 Dec '10

20 Dec '10

I'm observing a crash on qm_free, when we made two outgoing calls to the same number. One SIP phone receives ring back tone and the other busy tone. The back trace is shown below which shows that it is crashed in abort(). How can the condition if (f->u.is_free){ could be true? Please let me know if anybody observed this issue and let me know how to debug this isssue. f=(struct qm_frag*) ((char*)p-sizeof(struct qm_frag)); #ifdef DBG_QM_MALLOC qm_debug_frag(qm, f); if (f->u.is_free){ LOG(L_CRIT, "BUG: qm_free: freeing already freed pointer," " first free: %s: %s(%ld) - aborting\n", f->file, f->func, f->line);* abort();* } MDBG("qm_free: freeing frag. %p alloc'ed from %s: %s(%ld)\n", f, f->file, f->func, f->line);

new: pkg monitoring and troubleshooting enhancements
by Daniel-Constantin Mierla 20 Dec '10

20 Dec '10

Hello, I have committed some code to allow easier troubleshooting and monitoring of PKG usage per process. One new functions are exported by cfgutils module: - pkg_summary() - can be used to dump summary of PKG usage Btw, there was also added shm_summary() that dumps the summary of SHM usage. The kex module exports a new rpc command 'pkg.stats' that prints PKG usage metrics (used, free, real_used) per process. Here is a sample output: sercmd> pkg.stats { entry: 0 pid: 4793 rank: 0 used: 124788 free: 3813512 real_used: 380792 } { entry: 1 pid: 4794 rank: 1 used: 132740 free: 3805512 real_used: 388792 } { entry: 2 pid: 4795 rank: 2 used: 132740 free: 3805512 real_used: 388792 } The adding free to real_used values results in pkg memory size per process (4MB in this example). To get these stats, you have to compile with MALLOC_STATS enabled (this is default for Kamailio, so nothing actually to do for it). One benefit of this pkg.stats is ability to monitor usage of private memory and trigger alerts if the amount of available memory (free) for one process goes below a lower limit, useful when there is a memory leak (so you restart in time and report the problem) or the config operations for given traffic needs larger PKG size. In the near future there will be some new additions to be able to access these values also via PVs. Testing and feedback is appreciated.

Kamailio Compatability with Elastix
by Kurt Mullen 17 Dec '10

17 Dec '10

Well I finally made some progress. I have Kamailio 3.1.0 installed on one server and Elastix 2.0.3 installed on another server. The Kamailio server queries Elastix for authentication, and the SIP clients are able to register with Kamailio. However, the clients cannot call each other. Also, extensions added in the Elastix interface cannot authenticate with Kamailio. I have to manually add the users in the Asterisk database using mysql commands to get the authentication to work. I will need to use a GUI for staff to add / delete numbers. Am I way off base here? Kurt Mullen

Changing the text of reason header in CANCEL messages
by Klaus Feichtinger 16 Dec '10

16 Dec '10

Hello, I want to ask if you know any possibility in changing the text of the SIP reason header in CANCEL requests. Is the limitation still the same as described in the mail below from May 2010? For my scenario I have to use the TM module, because incoming requests from the PSTN gateway are parallelly forked to two destinations. Whenever the pending call is cancelled by the PSTN gateway the CANCEL request is still containing a reason header (Q.850;cause=16). But I would like to adapt the text of this header according RFC3326 (e.g. 'Reason: SIP ;cause=487 ;text="Request Terminated"'). The feature "e2e-cancel-reason" is working fine - the original text is copied, but no textops function can make any change..... Is there any trick possible to change the text of this header before it is handled by the proxy (e.g. in creating a spirale - change the text and forward it to the same proxy again)? Or in worst case if this is currently absolutely impossible - would this be an acceptable request for a new feature in any upcoming release of Kamailio 3.1.x? In the release 3.1.x it is still possible to store the text of an incoming reason header, so I guess it could be no problem in overwriting this text with any function...... Is anybody else interested in this feature? regards, Klaus ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Am 21.05.2010 09:26, schrieb François BERGANZ: When I use forward, it doesnt work!

TCP Overload Congestion
by Jijo 16 Dec '10

16 Dec '10

Hi Andrei, I'm observing TCP Recv buffer getting full when we are doing a load run (30cps) on Proxy with TCP. Basically the congestion is happening on the TCP connection from SIP Server to Proxy. I beleive kamailio is not processing the message fast enough, due to this congestion is occuring. Did anyone observe this behavior? How do we resolve it? Thanks Jijo

Can't Auth against Kamailio 3.1.1 - fresh install
by Graham Wooden 16 Dec '10

16 Dec '10

Hi folks, Getting ready to stage my 1.4.2 upgrade to 3.1.1 - but apparently I am missing something pretty basic here as I can't get a test subscriber registered. Turned up debug and viewed the "401 Unauthorized" repeating messages. So I combed back through the INSTALL and the various references on kamailio.org. And for full disclosure, here are the relevant steps that I have took: Did a make clean on the source and re-did the make, which looks like: make FLAVOUR=kamailio group_include="standard mysql" include_modules="carrierroute acc mi_fifo kex tmx pv siputils mi_rpc" cfg all install Added my domain into kamctlrc. Created a fresh DB, started up kamailio and added a user: [root@qa-voip-01 kamailio-3.1.1]# kamctl add testnumber testpass new user 'testnumber' added Made the appropriate changes to the default kamailio.cfg by adding in the defines. Restarted kamailio - no errors and all looked good. At this point, all indications would think that I can get the subscriber registered and get the location table updated ... But no such luck: [root@qa-voip-01 kamailio]# kamctl ul show Domain:: location table=512 records=0 max_slot=0 Any thoughts on where to look? I have confirmed that the subscriber device is using the right credentials. Using plaintext and the password is in user's row in the subscriber table. I am sure it's something pretty basic; this is my first stab at 3.1 from my 1.4 production machines. Thanks, -graham

Delaying 200 OK sent to originator
by Dan-Cristian Bogos 15 Dec '10

15 Dec '10

Hey Guys, I came in need to delay 200 OK sent to originator, I know that is not the job of a proxy (not a perfect world though), so if anyone think that should be in theory at least possible with kamailio/sr, I would appreciate any tip. Scenario: User A -> Proxy -> User B. User B will send 183 and then 200 to the User A. I would need to delay the 200 OK sent to User A with a number of seconds, but still send ACK to User B to "fake" the receiving of the message in time. When the ACK for the delayed 200 OK comes back from User A, I would simply absorb it. Would that be possible with kamailio/sr without using an external application? Ta for any kind of tip! DanB

Kamailio 3.1 and Elastix 2.0 Integration
by Kurt Mullen 14 Dec '10

14 Dec '10

I have two separate servers. A Kamailio box and an Elastix box. I have Kamailio all up and running. I installed Elastix 2.0 using an ISO. I followed all the steps to modify the Asterisk configuration from Kamailio 3.1.x and Asterisk 1.6.2 Realtime Integration using Asterisk Database to provide access to the asterisk database. 1) I am not able to register an X-lite softphone to Kamailio. a. Is this because Kamailio is not talking to the Asterisk DB or, would X-Lite connect to Kamailio anyway? b. kamailio.cfg : i. #!ifdef WITH_ASTERISK ii. asterisk.bindip = "192.168.15.211" desc "Asterisk IP Address" iii. asterisk.bindport = "5080" desc "Asterisk Port" iv. kamailio.bindip = "192.168.15.249" desc "Kamailio IP Address" v. kamailio.bindport = "5060" desc "Kamailio Port" vi. #!endif 2) From the Kamailio server I am able to make an MYSQL connection to the remote Elastix server. a. #!define DBURL "mysql://openser:openserrw@localhost/openser" b. #!define DBASTURL "mysql://asterisk:asterisk1017@'192.168.15.211'/asterisk" 3) From the Elastix server I am able to make a MYSQL connection to the remote Kamailio server (not sure this is necessary) Some items are unclear to me in the tutorial. 1) The first two steps, MYSQL INSTALLATION and INSTALL UnixODBC is this just on the Kamailio server, the Asterisk Server or both. 2) After creating the database on the Kamailio server "/usr/local/sbin/kamdbctl create" is the asterisk database configured on the Asterisk server? 3) After creation of the asterisk database, is the ODBC configuration on the asterisk server, Kamailio server, or both? 4) Note: "Be sure you configure Asterisk to not authenticate SIP requests coming from Kamailio". How do you do this? Kurt A. Mullen Practical PC, LLC (O) 830.542.4102 x204 (F) 210.767.3912

Dialog module with 2 servers and 2 separate databases.
by Pan B. Christensen 13 Dec '10

13 Dec '10

Hello, My customer has the following database design. Voip server 1 talks to SQL server 1. Voip server 2 talks to SQL server 2. Voip 1 and Voip 2 are load-balanced. Each SQL server has two databases. Database 1 contains semi-static data like call forwarding properties for users and is read-only. This is replicated from a third SQL server which the web interface writes to. Database 2 is read/write, is not replicated and contains data that is updated frequently like user location and now dialog info. Voip server 1 is not allowed to talk to SQL server 2 and vice versa. I'm using forward() to send authenticated REGISTERs to the other server so that it'll write this to RAM and its own SQL server. Thus, both servers are aware of clients authenticated and registered by the other server. How can I make both servers be aware of active calls on the other server? The customer is looking into possibly changing their design, but this may be a lengthy process involving lots of people. With kind regards, Pan

Trying to drop invite 200ok reply in onreply_route
by nikita 13 Dec '10

13 Dec '10

Hello, I'm using kamailio 3.0 with mediaproxy and I want to cancel calls if I have no mediaproxy relay connected to my mediaproxy dispatcher. In my request route I'm checking if "use_media_proxy()" is returning me a positive result and it's working fine : use_media_proxy(); if($rc < 0) { sl_send_reply("480","Temporarily Unavailable"); exit; } But I'm also want check in my onreply_route If I still have an active relay because I need to rewrite the sdp in the 200/OK reply. My problem is that I don't know how to end the transaction, I have tried : if (is_method("INVITE") && status == "200") { #!ifdef WITH_MEDIA_PROXY use_media_proxy(); if($rc < 0) { xlog("L_ERR", "invite reply error $rc \n"); dlg_bye("all"); } #!endif } and also : if (is_method("INVITE") && status == "200") { #!ifdef WITH_MEDIA_PROXY use_media_proxy(); if($rc < 0) { xlog("L_ERR", "invite reply error $rc \n"); drop(); } #!endif } In both case I'm seeing in my log file that use_media_proxy() returned me -1, but the reply is routed to the caller ... Any idea on how I can cancel my call in the onreply_route ? Also, I don't know if it's a good thing to make a second call to "use_media_proxy" in the onreply_route, mediaproxy module couldn't reply me with a different relay address if I have multiple mediaproxy relay? Regards, -- Nikita

Dispatcher Crash when all hosts are invalid

lcr in 3.1 - no reload without Siremis?
by Anders 10 Dec '10

10 Dec '10

I am upgrading from 1.5 to 3.1, but ran into some issues. The one right now is that I can’t seem to use the lcr and gws, although I’ve spent quite some time looking at the documentation. When it hits the next_gw() inside my route[PSTN] it finds nothing, and I have already added to the tables. But I added it manually to the tables, so maybe I needed to load them to memory – but “kamctl lcr reload” has been discontinued, so no loading. Is Siremis necessary as the input tool for lcr and gws? Just to make sure that it's not because of my cfg - here is the part of the cfg where it returns false in next_gw(): route[PSTN] { if (is_method("INVITE")) { t_on_reply("REPLY_ONE"); t_on_failure("FAIL_ONE"); if (!load_gws(1)) { sl_send_reply("500", "Our mistake - cannot load gateways"); exit; } if (!next_gw()) { sl_send_reply("503", "Service not available (no more gateways)"); exit; } } if (!t_relay()) { sl_reply_error(); } exit; } Any ideas what is wrong? //Anders

It calls load_tm this way (purple.c): if((load_tm=(load_tm_f)find_export("load_tm", 0, 0))==NULL) But all other modules call it this way: if((load_tm=(load_tm_f)find_export("load_tm", NO_SCRIPT, 0))==NULL) NO_SCRIPT is defined as -1. So I believe just changing the above will permit to load the module.

TCP Overload Congestion
by Jijo 09 Dec '10

09 Dec '10

Hi Andrei, I'm observing TCP Recv buffer getting full when we are doing a load run (30cps) on Proxy with TCP. Basically the congestion is happening on the TCP connection from SIP Server to Proxy. I beleive kamailio is not processing the message fast enough, due to this congestion is occuring. Did anyone observe this behavior? How do we resolve it? Thanks Jijo

Dialplan help
by Phillman25 Kyriacou 08 Dec '10

08 Dec '10

Hi I was wondering if you could help, I am trying to match more than one expression in the dialplan list when a request for an invite is received. My purpose is to authenticate source ip with the correct prefix so I want to match both prefix+source ip before allowing to proceed with a specific entry in dialplan list. Can that be done using Siremis v2 ? Thanks! Phillip

gws with same ip
by Anders 08 Dec '10

08 Dec '10

Hi, Running Kamailio 1.5: I have two different trunks with one carrier. The IP where I send the INVITE is the same, but the prefix differs. So in the gw table, I enter the two lines, - same IP, but with different digits in the 'tag' column, and different grp_id numbers. I then set up the lcr table and point to the respective grp_id's in the gw table. Problem: it ignores the grp_id when I make a call, meaning that when there are two gw's with the same IP address, it just takes the one that comes first, even though it doesn't have the grp_id I asked for in the lcr table. Is this normal behavior? If so, how do I get around this? Thanks! --Anders

whereis the serctl utility or its replacement
by rbond1 08 Dec '10

08 Dec '10

Hello. The documentation i see on the web keeps mentioning SERCTL to do management of users and other admin. Can someone provide a link to more relevant information on that utility or it's python replacement? I have compiled ser under ubuntu with mysql support, but now i need something that will help me add contacts to the database easily as the docs imply. The version of ser i pulled using the download information is ser 3.2.0-dev1 according to the sercmd output. Is the sip-router.org site also where SERCTL can be downloaded? What is the git string to aquire it if so? thx

Store Source IP in DB
by Bernhard Suttner 07 Dec '10

07 Dec '10

Hi, I am using Kamailio with usrloc, nathelper and register module (and some other). All the data will be stored within a MySQL database. The contact address will be stored within the database. Is it somehow possible to store the SOURCE-IP of a incoming REGISTER from a phone to Kamailio somewhere in the database? It's just for debugging purposes. Best regards, Bernhard

Kamailio 1.5.4 notls Core Dump
by Stagg Shelton 07 Dec '10

07 Dec '10

Kamailio 1.5.4 segmentation faulted today. I was able to determine with gdb that the error occurred at mediaproxy.c line 1104. Line 1104 is a call to memcpy Core was generated by `/sbin/kamailio -m 512'. Program terminated with signal 11, Segmentation fault. #0 0x00007f1469db6bb5 in replace_element (msg=0x77e470, old_element=<value optimized out>, new_element=0x7fffbd553210) at mediaproxy.c:1104 1104 memcpy(buf, new_element->s, new_element->len); 1.5.4 is new to our production environment, we were previously running 1.5.2 notls (also no mediaproxy) for more than a year without issue. 1.5.4 notls with mediaproxy has been running in our lab and preproduction QA environments since March of this year without any real segmentation faults. Does anyone have any ideas of what may have caused this, or suggestions to get around this. I do see that 1.5.5 is available, although there does not appear to have been too many changes to mediaproxy.c Thank you in advance Stagg

Kamailio and Asterisk Integration
by Kurt Mullen 07 Dec '10

07 Dec '10

There is a tutorial posted at <http://kb.asipto.com/asterisk:realtime:kamailio-3.0.x-asterisk-1.6.2-astdb> http://kb.asipto.com/asterisk:realtime:kamailio-3.0.x-asterisk-1.6.2-astdb I am confused. It seems that this tutorial has Asterisk AND Kamailio on the same physical server. If this is true, why would you do that. I thought the point was to move Kamailio to a separate server to handle all the SIP sessions and have Asterisk on another box to handle media, such as voicemail, IVR's and such. If I am correct, can someone give guidance on how to integrate if Asterisk is on a separate server? Thanks, Kurt

presence_xml and xpath
by Andreas Granig 06 Dec '10

06 Dec '10

Hi, I'm having troubles fetching an xpath from an xml document using presence_xml, so I probably do something wrong (using kamailio 3.0.x): $xml(x=>doc) = '<?xml version="1.0" encoding="utf-8"?><presence xmlns="urn:ietf:params:xml:ns:pidf" entity="sip:test@mydomain.com"><tuple id="86ae65b7-42de-4399-b635-295caad13aac"><status><basic>none</basic></status></tuple></presence>'; xlog("L_INFO", "all=$xml(x=>doc)\n"); -> prints the whole document, which is ok xlog("L_INFO", "tmp1=$xml(x=>xpath:/)\n"); -> also prints the whole document (including the xml tag in the beginning, not sure if this is ok) xlog("L_INFO", "tmp2=$xml(x=>xpath:/presence)\n"); -> prints an empty string How is this actually supposed to work? What I'd like to do in the end is extracting for example the "none" from the "basic"-tag by specifying "xpath:/presence/tuple/status/basic", which also returns an empty string now, also when appended with "/text()". Thanks a lot, Andreas

compiling the SER router
by rbond1 05 Dec '10

05 Dec '10

Hello. I am new to this forum. Can someone point me in the correct direction regarding compiling the SER package from the sip-router git repository? When I try to compile the binaries, it is having troubles finding the mysql.h header file. I have looked in some of the obvious places, but it is not installed either in the distro I for mysql nor in the sip-router directory's module folders. Here is the error I see in the make_and_install_output.txt file when I try to compile. km_dbase.c:38: fatal error: mysql/mysql.h: No such file or directory compilation terminated. make[1]: *** [km_dbase.o] Error 1 make: *** [modules] Error 1 I am using the current ubuntu server distro. Is this a well known issue? I followed the download instructions from the sip-router download page from this website so I assume it automatically pulled the most current release (?). Will I need to load a package from someplace else? Mysql is currently installed onto my machine. But I cannot find mysql.h. WIll I need to get the libs from mysql (if available) and will they include the header files? thx in adv

[Kamailio]: INVITE Authorization
by Spinov Evgeniy 03 Dec '10

03 Dec '10

Hello. I have Kamailio ( K in further ) and 2x Asterisk boxes ( A1 and A2 in further ) configured, so UAC registers at K and when it sends a call, it's routed to A1 or A2, balanced. The problem is, that I cannot find how to authorize INVITE requests, so unregistered UAC could not send INVITE requests. Simply cannot find anything. I'm making registration, using www_authorize() and checking all INVITES with proxy_authorize(). Just after kamailio is started - everything works fine and as planned: registered UAC can call and not registered - cannot. But after aproximately 40 seconds everything is stopped. Not calls passed and everybody receives 407 Proxy Authorization is required. So, the question: how it is correctly to verify that incoming INVITE on K is authorized? It seems to me that I'm doing that in wrong way. Thank you.

using forward() with variables
by Pan B. Christensen 03 Dec '10

03 Dec '10

Hello, We are running Kamailio 1.5. I'm trying to use the forward() function with a variable like this: forward($shv(voip1-edge1)); That fails to parse. I then tried this, which I thought would fail: forward("$shv(voip1-edge1)"); That parsed correctly, but it then failed to resolve the domain '$shv(voip1-edge1)' as expected. Why can this function not use variables? I tried to make a workaround by doing this: $du=$ru; $dd=$shv(voip1-edge1); forward(); That also failed. Why is $du writable but $dd is not? I then made a fourth attempt, which seems to work: $du="sip:" + $shv(voip1-edge1); forward(); With kind regards, Pan

Hello Kamailio (OPENSER) Team, We have successfully installed kamailio on debian flavor of LINUX as per your documentation states. After installation kamailio is running on the server and we are trying to register a SIP User Agent to kamailio SERVER. But when we try to register, the server is returning these set of messages to us. 1st Message : 401 Unauthorized 2nd Message : 200 OK 3rd Message : 401 Not Here Looks like we are missing something in the configuration file for kamailio. Can you please guide us through the process so that we can get this working. I am attaching my kamailio.cfg file with the mail as well as the ethereal captured log file in format of .jpg file with the mail. We also want kamailio to listen on multiple ports such as 5060 and 5062 and we have made according changes in the configuration file as well. Please have a look at those as well and tell us whether we are doing it right or not. Also if you feel that we need to do some additional changes in configuration file. Please suggest them.

When too many calls, calls does not complete, too much delay when placing calls
by Vic Jolin 02 Dec '10

02 Dec '10

Hi all, Just want to ask if anybody here has come across this problem of mine, when single call proxy is ok, but when you send more traffic to it, calls somehow get stuck, trying to make a new call it takes a lot of time and so it times out. Does anybody know what could be the problem? Thanks!

limit on fail-over in lcr?
by Anders 02 Dec '10

02 Dec '10

Hi there, Kamailio 1.5: I cannot find an answer to this in the documentation: Is there a limit to how many fail-overs Kamailio does? I have lcr setup for a destination where it is rejected with 403 on the first and second priority, but then it goes no further, even though I have a third priority defined. Is there a limit to fail-over on two levels? Thanks!! //Anders

Re: [SR-Users] SIP between IPv4 and IPv6 agents

When you call force_rtp_proxy() then you have to provide the i/e flags to tell rtpproxy how it should bridge the call. Therefore you need to know for every call: - is the caller IPv4 or IPv6? - is the callee IPv4 or IPv6? Finding out the protocol version of the caller is rather easy: if (af == inet) { # caller ipv4 ... } else { # caller ipv6 ... } But finding out if the callee is v4 or v6 is difficult. Actually it may even be that the callee is registered with 2 clients at the same time - one using v4 and v6. As far as I know this multi-registration scenario can not be handled currently - only single-registrations or multi-registrations which use the same protocol version are supported. Anyway - there are several approaches how to detect the IP version of the callee. - fixed mapping: for example if you know that all usernames starting with 1 are IPv4 clients, and all usernames starting with 2 are IPv6 clients, then you can detect the callee's protocol version manually, e.g: if ( $(rU{s.substr,0,1}) == "1") { # callee ipv4 ... } else { # callee ipv6 ... } - check destination URI if it contains a IPv4 or IPv6 address, e.g. use http://www.kamailio.org/dokuwiki/doku.php/transformations:devel#resubst_exp… to test if $dd contains '.' which would indicate a ipv4 address. - use dedicated location tables > (Because it uses them, for instance here: if (method == "REGISTER") > { if (af == inet) { save("location-inet4"); } else if (af == inet6) > { save("location-inet6");...) > > If I do not have to use it, I do not need to merge it with my > kamailio.cfg file, the steps I have to do are: install rtpproxy, > start it with the appropriate parameters and set the forcing in the > kamailio.cfg file?! The more I think about it I prefer the approach with separated location tables. It should be rather easy to integrate the 2 location tables into your existing config. regards Klaus PS: please Cc the mailing list

Parallel forking and recording with rtpproxy?
by Jeremya 02 Dec '10

02 Dec '10

Hi, I'm having some issues with recording in rtpproxy when I parallel fork an incoming call. The scenario is that I want to record incoming calls to a small number of operators, and the call is converted to an 'all-call' by the local kamailio instance - parallel forking. It appears - though I could be wrong - that only the call tag is used to differentiate calls in kamailio/rtpproxy. I am guessing that when the call is forked and presented to rtpproxy that it somehow creates/uses only one data structure. When the call is answered, the other calls are cancelled and this results in the data structure being deleted. Is this correct? If so, are there any easy ways to achieve recording in this scenario? Thanks Jeremy

nathelper force_rtp_proxy etc flag "f"
by Jeremya 02 Dec '10

02 Dec '10

Is the flag "f" of any actual use in force_rtp_proxy, rtp_proxy_offer and rtpproxy_answer? With an upstream proxy the lack of "f" causes problems. Does some problem occur when it is used without an upstream proxy? Thanks Jeremy

by Daniel-Constantin Mierla 02 Dec '10

02 Dec '10

Hello, there are almost 2 months since release of Kamailio 3.1.0, so it is time for 3.1.1 as there were several important fixes done. I propose Thursday, next week, by that time we should sort out most of the issues reported lately. Other opinions?

The strange thing is that this problem occurs only when I try to load Permissions and Drouting modules at the same time: whenever I load anyone of that two modules alone Kamailio starts whitout complaining about anything. Obviously I have already checked the value of "table_version" in version table and it's the correct one (5). Moreover I have also tried to apply the patch suggested in the following thread for a similar problem, (http://www.mail-archive.com/sr-dev@lists.sip-router.org/msg07551.html) but without any success. Please let me know if you have some advice for my problem, I really need to use these two modules at the same time! Greetings, Pierpaolo Culurciello

CANCEL with Totag
by Iñaki Baz Castillo 01 Dec '10

01 Dec '10

Hi, Samsung PBX's generate a wrong CANCEL: - It contains To tag !!! - It contains "application/sdp" mirroring the SDP of the 183 received !!! Really ugly. Actually those CANCEL's are being rejected by my kamailio (403) as they contain Totag but no Route header. So, as a workaround, I will move the section of CANCEL before the loose-routing section. I expect it will work, but I would like to be sure that Kamailio (1.5) will not react due to the Totag of the CANCEL (it shouldn't IMHO as the Totag has no relationship with the INVITE transaction being cancelled). Thanks a lot. -- Iñaki Baz Castillo <ibc(a)aliax.net>

Kamailio 3.1 doesn't start with siptrace module
by vonlouda 01 Dec '10

01 Dec '10

Hi, I've installed a new instance of Kamailio 3.1 without prb and it works fine. However, in order to activate siptrace, I've added the following lines in the config file, loadmodule "siptrace.so" modparam("siptrace","db_url", DBURL) modparam("siptrace","table","sip_trace") modparam("siptrace","trace_on",1) modparam("siptrace","trace_flag",13) I had the following message in kamailio logs: Dec 1 17:17:55 km36133 /usr/sbin/kamailio[5522]: INFO: usrloc [hslot.c:53]: locks array size 512 Dec 1 17:17:55 km36133 kernel: [10765022.447713] kamailio[5522]: segfault at 0 ip 0 sp 7fffffffc748 error 4 in kamailio[400000+1f7000] Dec 1 17:17:55 km36133 kamailio: ERROR: <core> [daemonize.c:269]: Main process exited before writing to pipe Is it a known issue? Do you have an idea how to fix that, or at least how to activate siptrace module without craching Kamailio. Regards.

memory debugging
by Jason Penton 01 Dec '10

01 Dec '10

Hi All, thought I would give you a small little perl program I quickly hacked up to help with some memory leaks I was getting. Turns out I was forgetting to call release_urecord after a get_urecord on the usrloc module. Because I use Kamailio in DBOnly mode - the memory was never being freed. This little program helped me to find the source in no time at all. I hope it helps you too. A little info: The program works on the log file. NB you have to have memlog debugging enabled for this program to do anything useful. Effectively the program continuously monitors the log file looking for allocs and frees. It tallies all the fragments in use and gives a report of all the fragments and where they weer allocated. It also keeps a running counter of bytes used. Here is an example of the output: ***************************************************************************************************************************************************** DUMPING ALL UNFREED MEMORY FRAGMENTS (25) ***************************************************************************************************************************************************** called from h_table.c: build_cell(251) 6 21312 called from dlg.c: new_dlg_uac(169) 1 128 called from t_msgbuilder.c: build_uac_req(921) 6 1896 called from pv_svar.c: set_var_value(104) 3 132 called from ../../ut.h: shm_str_dup(501) 2 48 called from reply.c: build_contact(127) 1 132 called from t_hooks.c: insert_tmcb(108) 6 144 ************************************************************TOTAL BYTES HELD IN FRAGMENTS: 23792*************************************************************** To use - simply untar into a directory and run ./memalyze.pl Hope it helps Cheers Jason

VIA header x-route-tag
by alex pappas 01 Dec '10

01 Dec '10

Dear All, We have some cisco gw that they send to the Kamailio in the first invite and inside the VIA header an x-route-tag="The Gateway that the call entered". I'm trying to add this to the acc module in order to have it recorded but without sucess. My config is this: if (search("x-route-tag")) { avp(s:xroutetag) = $sel(@via); xlog("----- We have a x-route-tag in the SIP msg avp: $avp(s:xroutetag) -----"); }; I'm trying to add the VIA header to an avp so I could manipulate the string but i cannot implement this. Does anyone can suggest a way to add the *x-route-tag* value to an AVP? Thank you in advance Alex sample VIA header: Via: SIP/2.0/UDP 10.0.0.15:5060;* x-route-tag="tgrp:TANDEM-KOR"*

Redirect w/ Xlite?
by Eric Hiller 01 Dec '10

01 Dec '10

Hello all, I have seen some other complaining about this issue, but the posts were over 4 years ago so I would think xlite would be fixed at this point. I wanted to ensure my formatting was correct before I started trying other phones. All I am trying to do at the moment is a simple redirect. My config is: xlog("tu= $tu || $(tU{s.select,0,-}) \n");rewritehost("pbx.newhost.com");xlog("host is now $rd; all is $ru\n");sl_send_reply("300","Redirect");exit; Insanely simple, however xlite is not redirecting the actual ip of the next invite/register/whatever. It only changes the RURI, but not the actual ip. Per the RFC, it looks like I am doing this right, the new host is in the contact field of the 300 and the client should then redirect its next packet to the new host. Any ideas what I am doing wrong here? Or is this a known redirect issue. And given that, how supported is redirect? Should any system be based upon it? Thanks for the help!-Eric

has_sdp() missing
by Jeremya 30 Nov '10

30 Nov '10

Hi, I've been following some examples using has_sdp() function but it is not supplied by 3.0.x TEXTOPS I've seen some discussion on mailing lists about has_sdp() being included since 1.5. But checking the online documentation is doesn't exist in any version. I use has_body("application/sdp") as an alternative but perhaps the has_sdp() function could be included, or references and examples using it altered or removed? Thanks Jeremy

Re: [SR-Users] SIP between IPv4 and IPv6 agents
by Komáromi Péter 30 Nov '10

30 Nov '10

Hi again, My kamailio 1.5 is working well and I'm able to create the session between an IPv4 and an IPv6 UA, but there is no RTP session. That's the point where the rtpproxy comes in. I installed it, and made a bridging (I hope it is): /usr/local/bin/rtpproxy -F -l /192.168.124.146 -6 FEC0:0:0:0:0:0:0:2 and started rtpproxy -F start. But there is no RTP traffic yet. I read here ( https://www1.ethz.ch/id/people/allid_list/armin/SIP-IPv4-IPv6.pdf ) I have to make two tables named â01Clocation _inet4â01D and â01Clocation_inet6â01D instead of the only â01Clocationâ01D. If it's true, were can I add these? Because it says: "If mySQL is used, the mySQL initialization script (/usr/local/sbin/ser_mysql.sh) has to be modified to create two additional tables" But there is no /usr/local/sbin/ser_mysql.sh on my computer. Where else can I add these tables? Thanks, Peter

Tutorial: FreeSwitch as Media Server and SBC for Kamailio 3.1
by Daniel-Constantin Mierla 30 Nov '10

30 Nov '10

Hello, a short note to inform that I updated my tutorial about using FreeSwitch and Kamailio together for large VoIP platforms. Besides upgrade to use latest Kamailio major stable release, v3.1.0, there are couple of new features added in the architecture of the VoIP platform: - along with providing media services (voicemail, conferencing, a.s.o.), FreeSwitch is used now also as SBC for topology hiding and media relay (this helps for transconding needs, palying audio messages during the early session or NAT traversal) - Kamailio config has added features to detect DoS/DDoS and scanning attacks, secure SIP communication over TLS, IP authentication and a bunch of neat things that help for an easier maintenance and update of parameters such as database connectivity details, local IPs, etc. The link to tutorial is: * http://asipto.com/u/kfsb Hope it will be useful for many of you.

Failover with SRV records
by Eric Hiller 30 Nov '10

30 Nov '10

Sorry all for the second question of the night as I go through working out bugs in my setup. I want to use SRV records to loadbalance across hosts. This works great, when all the hosts listed in the SRV are up. However, I want kamailio to use the next host if the current hosts fails. I tried just setting up a new branch, but kamailio keeps using the same SRV entry over and over on that transaction, only a new transaction seems to give kamailio a chance to use a different SRV entry. Any ideas as to how I can force kamailio to try the next SRV entry if the first one fails? For example I t_relay to 2.domain.com which has a _sip._udp.2.domain.com entry for hostA and hostB. If hostB is down, but kamialio decides to send to hostB it just keeps doing so even though hostA is perfectly up it doesn't try for it. Is there a way to remove hostB from the kamailio try list? Or as an alternative to do a manual SRV lookup on 2.domain.com and then put then in a variable and go through them one by one manually? Ideas? Thanks-Eric

Settings adjustments
by Javier Gallart 29 Nov '10

29 Nov '10

Hello I have a Kamailio acting as Redirect server. In some cases I need to include more that 12 Contact headers in the 302 message. I've set these values in the config.h file. #define MAX_BRANCHES 20 /*!< maximum number of branches per transaction */ #define MAX_REDIRECTION_LEN 756 /*!< maximum length of Contact header field in redirection replies */ Could these settings cause any "collateral damage"? Thanks! Javi

SIP between IPv4 and IPv6 agents
by Komáromi Péter 29 Nov '10

29 Nov '10

Hello! I write my diplomawork, and kindly ask for your help! I would establish a videoconference with SIP protocol between two PCs, one of them using IPv4 and the other uses IPv6. I have access to an RMX 4000 Multipoint Conference Platform with a Kamailio SIP server on it. Were here on the mailing list any previous discussion about translating between the two IP versions? I read some about RTP Proxies, but did not find the proper solution so far. Could somebody help me please? Best Regards, Peter

never write private emails. They will be simply discarded. ngrep gets the traffic before the firewall.

SER proxy drops incoming SIP requests
by Igor Potjevlesch 24 Nov '10

24 Nov '10

Hello, After days of debugging, I'll need some help from the SER specialists to troubleshoot this problem. The SER version in service is: 0.9.9+cvs20090925 It's running on a Red Hat EL 5.3 server. I currently have about 10.000 users registered. I encounter several seconds (1 to 5) without replies from the SIP proxy every 30 seconds. Some requests are delayed, but most of them are not replied at all. At the same time, all the 6 SER childs (forking is enabled) get about 100% used CPU (from "top") After some troubleshooting, I found that the rythm of those deny of service was exactly the time configured as the "timer_interval" parameter of "usrloc" module. When changing the parameter, problem rythm changes as well. What we did so far: - Check DNS and MySQL performances - Moved the number of childs from 6 to 9 - Changed the "timer_interval" ("usrloc" module) from 60 to 900 - Stopped the "natping" feature ("nathelper" module) as it impacted the service as well. Please let me know if the problem has already been observed and what would be the best way to go deeper in the troubleshooting. I need to solve that as soon as possible: some of our users higly suffer of random REGISTER not beeing taken into account. Sincerely, Igor

Unforcing RTPProxy for a Cancel
by Joe Hart 24 Nov '10

24 Nov '10

I'm trying to figure out if there is some way to identify a call for which an rtpproxy session has been set up when the call is cancelled. I can't check the flag I set for the call, nor can I check the route param I set (which is what I'm doing to figure out when to unforce the media stream for a BYE). If this is not possible, is there any danger in calling unforce_rtp_proxy() for all calls, regardless of whether media proxying has been set up for the call or not? -- Joe Hart Voice Systems Integrator Evariste Systems LLC 1170 Peachtree Street 12th Floor, Suite 1200 Atlanta, GA 30309 Tel: +1-678-954-0670 Fax: +1-404-961-1892 Web : http://www.evaristesys.com/

TCP Children and Connection Handling
by Jijo 24 Nov '10

24 Nov '10

Hi All, I'm facing an issue with TCP connection from Proxy(kamailio) to a SIP server on a load test, where kamailio is not processing the message fast enough and which leads socket buffer getting filled up. I have increased the tcp_rd_buf_size but that really didn't help. According to my understanding the each TCP connection is assigned to a TCP children, and TCP children will read until it there is no data for few seconds and return the connection to tcp main process. In this case the TCP connection is to the SIP server which always have some data due to periodic SIP ping ,registration refresh and calls etc. So i believe this connection will be hold always by one children and since that children is processing the message sequentially, it might not be possible to increase the performance on this connection. My question is, If my understanding is correct How do we increase the performance for a particular TCP connection? Does Kamailio has some mechanism to distribute the message from a single TCP connection to different child, when it is overloaded? What is the best way to solve this issue? Thanks in advance. Jijo

avp_db_query returning wrong data

23 Nov '10

Hi All, While doing 5 REGISTER/second, i observed that that avp_db_query is returning data from a different db entry. This happens only with TCP with more than 1 tcp_children. it works fine with UDP. It also work with TCP with tcp_children as 1. Is there any relation between the TCP connections and Postgres in kamailio. I'm using kamilio 3.1.0. How should i debug this issue?? What are the areas need to look? Thanks Jijo

SIP Routing Logic in Lua
by Daniel-Constantin Mierla 22 Nov '10

22 Nov '10

Hello, during last days I spent some time to extend the native API exported to Lua. Many more functions exported by core and modules can be called from embedded Lua scripts. Note that you get also access to psedo-variable operations and you can call all functions exported by modules that have no fixup pretty safe, via sr.modf(...), without a need to be exported natively. I made an easy-to-do tutorial where all the SIP routing logic is implemented in a Lua script (including authentication, accounting, registrar, user location). You can read it at: http://asipto.com/u/h Therefore, if the configuration file language is not offering everything you need to route your SIP traffic, look at app_lua module and its API, it is a real option right now. Lua is a small and fast embeddable language, the interpreter is linked to and loaded by Kamailio at statup, therefore the performance penalty is not significant (Lua project site is: http://www.lua.org). It is also popular among other SIP telephony projects. Any kind of feedback is appreciated!

Storing multiple SQL results in htable/mtree
by Robert McGilvray 19 Nov '10

19 Nov '10

Hello, I'm interested in using the htable and/or mtree modules to keep my aliases and did lookups in memory to minimize the amount of SQL lookups that are being performed. It's easy enough to use htable to cache a single value after it is retrieved but what I'm not clear on is how I can do it when SQL returns multiple destinations. Consider the following query and returned results: SELECT username,domain,CAST(q_value AS CHAR) FROM aliases where alias_username = '10001' AND alias_domain = 'us.sip.globeop.com' AND active = '1' ORDER by q_value; +----------+--------------------+-----------------------+ | username | domain | CAST(q_value AS CHAR) | +----------+--------------------+-----------------------+ | 8500 | us.sip.globeop.com | 1.000 | | 3874 | us.sip.globeop.com | 1.000 | | 7050 | us.sip.globeop.com | 1.000 | | 2100 | us.sip.globeop.com | 1.000 | In my existing script I just append the results as branches and all works well but I end up with a lot of unnecessary SQL traffic. I see the htable supports array but I'm not sure how to go about assigning multiple values to a single key to use later. How can I take the above results and store them in memory for use by other transactions?

SIP Scanning Attacks Experiences
by Daniel-Constantin Mierla 19 Nov '10

19 Nov '10

Hello, during the testing period of Kamailio 3.1.0, while running it at voipuser.org, I had the chance to watch live and analyze a SIP scanning attack. Yesterday I noticed another one by looking at Siremis 2.0 charts, therefore I wrote an article with some hints about what you can use to protect your SIP services within Kamailio configuration file. You can read it at: * http://asipto.com/u/i Hope is going to be useful for many of you!

Hello, I'm having problems with my kamailio, my phones are unable to register into the Proxy. I have been checking with ngrep-sip and all i'm receiving is many REGISTER from the phones but never getting some response from the Proxy The Proxy has a public IP and the phones are behind NAT. The weir thing is that my logs are not showing any output...and as you can see on the script, i have a section to receive REGISTER requests.... if (is_method("REGISTER")) { if (!save("location")) { sl_reply_error(); } exit; } Thanks in advance for your help

Kamailio 1.5.4 - IP addresses WhiteList
by Miguel Baptista 17 Nov '10

17 Nov '10

Hi all, I want to enable pike module based on IP addresses. I mean ... I don't want to check if requests from some specific IP addresses trigged the Pike's threshold. but for all other IP addresses I want to check it. I was thinking about using some kind of IP addresses' whitelist. The userblacklist module has some whitelist but it's based on username/domain not IP addresses. Can someone please give me some advice how to implement it properly. Is there any module that will allow me to do it properly? Best Regards, Miguel Baptista

I mean if I have 3 gateways and the one of them is in Probing mode why Dispatcher is continuing sending there calls? Why this gateway is not changing from Probing to Inactive since is not replaying to OPTIONS messages send by Kamailio? Configuration: modparam("dispatcher", "flags", 2) modparam("dispatcher", "ds_ping_interval", 5) modparam("dispatcher", "ds_probing_mode", 1) modparam("dispatcher", "ds_probing_threshhold", 2) modparam("dispatcher", "dst_avp", "$avp(s:dst_avp)") modparam("dispatcher", "grp_avp", "$avp(dsgrp)") modparam("dispatcher", "cnt_avp", "$avp(i:202)") modparam("dispatcher", "ds_append_branch", 0) using db for gw: setid 123,destination sip:xxx.xxxx.xxx, flag 0 ... in ROUTE: if(ds_select_domain("$avp(s:disp_dstgrp)", "4")) in Failure Route if(!ds_next_domain()) I want Dispatcher when it sees a node gateway that is dead , to Not send any other calls.

Hello all, I am conducting some load testing and need to create 50,000 accounts on kamailio. I want to write a shell script to add 50,000 users. Kamctl add [user] [password] prompts for a password and I checked kamctl -help and there is no option for providing password along with the command. Is is possible to disable password and run my script? Thanks Sid "May the light be with you." ______________________________________________ Siddhardha Garige www.luminepixels.com

Regarding SER Listening on Custom Port
by Saurabh Srivastava 16 Nov '10

16 Nov '10

Hello SER Team, We have made SER listen on two ports via adding this command (listen=eth0:5060 eth0:5062) in ser.cfg file. Now we are able to get the server listening on two ports as 5060 & 5062 and it is sending 200 OK for the user agents which try to communicate on both the ports. SER is able to register two user agents, one on 5060 and one on 5062. But when we are trying to make a communication between the two registered user agents (i.e. one on 5060 and other on 5062) then no communication is possible (i.e. we cannot make calls and chats). Though when the two user agents are registered on same port (i.e. both UAs on 5060 or both UAs on 5062) then communication is possible between the two clients (i.e. we can make calls and chats). Can you people please guide me through that how can I make the 2 UAs registered to SER on different ports (i.e. one on 5060 and other on 5062) communicate with each other (i.e. they can make calls and chats). I have attached a log as well which shows the same problem. This is a wireshark captured output on the machine which has SER installed. Thanks and Best Regards Saurabh Srivastava
