IMPORTANT: acc module - SQL define removed and diameter code relocated
by Daniel-Constantin Mierla 09 Aug '17

09 Aug '17

Hello, I just pushed a bit of clean up to acc module, therefore be aware of following changes: 1) the define conditions on SQL_ACC were removed -- this was enabled for more than 10 years and only made the code look complex and hard to follow up its logic. 2) the code related to DIAMETER accounting was relocated to acc_diameter (new) module. It was a consistent size of code that was not enabled for sooo... long. It is now a dedicated module, similar to acc_radius. The diameter accounting code, even a new module now, is in the same stage, compiling but not tested, in pair with auth_diameter module, it may work, but very likely not. In summary, what's important for those using the acc module -- it offers the same functionality as it was enabled by default in the past 10 years or more, only the unused code was relocated. It offers the functionality of writing accounting records to syslog and sql databases. The acc module is now slimmer, only with the code that it needs, therefore easier to maintain and enhance for the future. Hopefully, there was no side effect with this update -- anyhow, if you find any issue, just open a bug report on github project.

Kamailio: how to route RTP media directly to endpoint
by Aleksey Hodin 09 Aug '17

09 Aug '17

Hi all, We have usual config Kamailio + Asterisk where Kamailio play as sip and rtp proxy. Kamailio have public IP, asterisk - no. All calls between clients now going like that: UserA ---sip--> Kamailio --> Asterisk --> UserB \-rtp--> Kamailio (rtpproxy) --> Asterisk --> UserB All clients of course from Internet and behind Nat. Main problem is amount of traffic going through Kamailio and Asterisk. We need to pay for every additional GB behind limit in tariff plan to hosting provider. So we decided to try route all rtp traffic between users directly. UserA ---sip--> Kamailio --> Asterisk --> UserB \-rtp--> --> --> UserB Is it possible at all? Maybe someone already did it ... -- BR, Alex

RFC: Moving misc/obsolete/ to its own git repository
by Daniel-Constantin Mierla 09 Aug '17

09 Aug '17

Hello, trying to make the git repository a bit slimmer and avoid unuseful indexing of unused modules, I am considering to move misc/obsolete to its own github repository (planned to be named kamailio-obsolete). The initial idea was to keep there modules that were duplicated or no longer maintained, just in case someone will come later and wants to revive it. However, iirc, it is more than 4 years and nobody touched them, so very likely it requires a bit of work to revive any of them, so a fresh re-import will be the same from an external repository. If anyone still wants to keep them in the main kamailio repository, respond on the mailing list and present the benefits. If not, I will do the operation in the next several days.

Core crash in del_lump() "offset exceeds message size" when using subst() inside tm:local-request route.
by Cody Herzog 08 Aug '17

08 Aug '17

Hello. Inside the tm:local-request route, I am trying to modify the body of outgoing NOTIFY messages using the subst_body() function. Things seem to work fine most of the time. The NOTIFY messages are correctly modified. However, I will very rarely hit a crash. I can force the crash to happen more quickly by stress testing with thousands of NOTIFY messages being modified. Is it safe to call subst() or subst_body() inside the tm:local-request route? If not, is there another way I can modify the outgoing NOTIFY messages safely? Note that I am also calling append_hf() inside the same tm:local-request route, but that has been working for a very long time without causing any problems. Could there be some kind of bad interaction between append_hf() and subst_body()? Strangely, it seems like using subst() makes the crash more likely to happen. For some reason, subst_body() seems to be more robust. Here are the logs I see: --------- Jul 28 10:57:40 SIPCOMM-VEGAS-TEST /usr/local/sbin/kamailio[2476]: CRITICAL: <core> [data_lump.c:292]: del_lump(): offset exceeds message size (1625 > 1194) aborting...

kamailio + dispatcher asterisks + pstn gateways
by Aidar Kamalov 08 Aug '17

08 Aug '17

Hello, Whats the best way to provide subject? Now I have central kamailio server and (asterisk "media" servers + asterisk pstn gateway in different cities). Kamailio default config with some changes in route[LOCATION] if (!lookup("location")) { $var(rc) = $rc; route(TOVOICEMAIL); t_newtran(); switch ($var(rc)) { case -1: xwarn("Contact $rU not registered. Forwarding call to dispatcher"); append_hf("X-External: true\r\n"); $rU = "00"+$rU; break; case -3: send_reply("404", "Not Found"); exit; case -2: send_reply("405", "Method Not Allowed"); exit; } } ...... # when routing via usrloc, log the missed calls also if (is_method("INVITE")) { setflag(FLT_ACCMISSED); } if(!ds_is_from_list()) { route(DISPATCH); } route(RELAY); So all calls going to asterisk server. Not local calls with 00 prefix. And asterisk context: context kamailio { _X. => { Noop(CALL to kamailio user ${EXTEN}); Dial(SIP/${EXTEN}@${SIPDOMAIN},60,RTt); Hangup; } _00X. => { Noop(CALL to external user ${EXTEN}); Dial(SIP/PSTN-SERVER/${EXTEN:2},60,RTt); Hangup; } } Is it right way? Maybe any better approach? How to keep route logic at kamailio, but use dispatcher asterisk to proccess the calls to pstn(all endpoints at one city to pstn asterisk at this city. In others city there are other pstn gateways)? -- Aydar A. Kamalov

Hi, I have an ongoing issue with kamailio...my softclient registered with kamilio originates a call which gets routed to another switch from kamilio and that switch terminates the call to B party side. Now once calls is established, B party sends BYE messages or (any re-INVITE during the dialog) which comes to the kamailio but kamailio is not relaying it to the A party...Can someone please help in this regard.

Question regarding t_check_trans()
by Joe Baran 07 Aug '17

07 Aug '17

Probably an elementary question, but we're relatively new at digging into the details. We are trying to understand the following block of config code and have a question or two. Our assumption is the t_precheck_trans() function tells us whether another packet has arrived already as a retransmission. However, we're not clear on what the t_check_trans() is doing assuming the condition is true. Any direction on this? Thanks. route[CHECK_RETRANS] { # handle retransmissions if(t_precheck_trans()) { t_check_trans(); exit; } } Joe Baran

Hello, I want to distribute endpoints calls in different cities to asterisks in the same cities where the endpoint. Now I use dispatcher for distibute calls beetwen asterisks, but without reference to the city. Can you please suggest better module and way for this? Is it better to distribute based on ip? Or may be based on groups? -- Aydar A. Kamalov

Pull Request or Issue? - coredump in case no contentLengthHdr present in REGISTER
by Valentin Christoph 04 Aug '17

04 Aug '17

Hi all, We have identified an IMS related issue, when the "Content-Length" header is missing in REGISTER request. It's a missing null pointer check in file modules/ims_auth/utils.c We are using Kamailio 4.4.5 for this purpose and we would need a fix in that release. I'm not sure, how to proceed now? Should I just create an "Issue" at GitHub, or is it possible for me to create a "Pull Request" at GitHub (would be less effort for you, I guess). Anyway, the change we did in our local GIT repository, is shown in following picture: [cid:image001.jpg@01D30C76.DE88AE10] Thanks, Christoph The information contained in this e-mail message is privileged and confidential and is for the exclusive use of the addressee.

thx. I just thought that it's possibe to concatenate both engines together. So this is my last question regardng kemi: Main goal why i still not use kemi at the my projects is a: TBD: the options for specific event_route blocks. Meanwhile, should work using hybrid configuration with request_route/reply_route/… in embedded interpreter and the other routing blocks in native kamailio.cfg. As i uderstand it is not possible to use event_route in a kemi. only native.

Sip-clients not connecting to kamailio, What am I missing?

Hi, I’m very new to Kamailio, in fact I have never got Kamailio to work properly. I’m following this tutorial http://kamailio.org/docs/tutorials/5.1.x/kamailio-install-guide-deb/ <http://kamailio.org/docs/tutorials/5.1.x/kamailio-install-guide-deb/> step by step, but my subscribers are not able to connect to Kamailio. (X-lite and Zoiper) I can install Kamialio, create the database, start Kamailio, add subscribers, without any failures or error messages. I’m running debian jessie. When i’m running wireshark I get the message Port unreachable. What am I missing? Can someone give me a hint on what I should look for?

route[LOCATION] is it bug?
by Aidar Kamalov 04 Aug '17

04 Aug '17

Hello, I 'm new in kamailio. I have kamailio with dispatcher and two asterisks. Endpoints register to kamailio. Calls beetwen endpoints going through dispatcher to asterisks. Calls to other destination rejected by kamailio with 404. But If i put xlog("AAAA") or xwarn in route[LOCATION] in if (!lookup("location")) block (default kamailio 5.0.2 config) calls to other destination goes through dispatcher to asterisks. I cant't understand WHY? :( (sorry for my bad English) route[LOCATION] { #!ifdef WITH_SPEEDDIAL # search for short dialing - 2-digit extension if($rU=~"^[0-9][0-9]$") { if(sd_lookup("speed_dial")) { route(SIPOUT); } } #!endif #!ifdef WITH_ALIASDB # search in DB-based aliases if(alias_db_lookup("dbaliases")) { route(SIPOUT); } #!endif $avp(oexten) = $rU; if (!lookup("location")) { xwarn("method ($rm) r-uri ($ru)\n"); ################## HERE ########################## $var(rc) = $rc; route(TOVOICEMAIL); t_newtran(); switch ($var(rc)) { case -1: case -3: send_reply("404", "Not Found"); exit; case -2: send_reply("405", "Method Not Allowed"); exit; } } # when routing via usrloc, log the missed calls also if (is_method("INVITE")) { setflag(FLT_ACCMISSED); } if(!ds_is_from_list()) { route(DISPATCH); } route(RELAY); exit; } -- Aydar A.

Kamailio inserting Quote " mark in SIP header
by Arslan Saeed 03 Aug '17

03 Aug '17

Hi All, We are seeing that Kamailio's nat_helper_module function of add_rcv_param(), inserts " (quote) mark to some of the SIP headers (as below in the contact header in sip 200 OK response) Contact: <sip:172.70.1.2:5060;bnc;received="sip:118.107.184.242:25090 ">;expires=172 We got few SIP UAs that are complaining about the quote mark inclusion in contact header and responding back with SIP 400 bad syntax status code. Requesting views / suggestions from community about this behavior of kamailio and any workarounds available. Cheers Arslan

Using a number as htable key name

03 Aug '17

Hello, I'm trying to use a htable to reroute some numbers but when i'm trying to use kamcmd to add a entry where the element name is a number instead of a string i get a 500 error kamcmd htable.seti force_number 1234 1 error: 500 - Not enough parameters (htable name, key name and value) Also with quotes i get the 500 error: kamcmd htable.seti force_number "1234" 1 error: 500 - Not enough parameters (htable name, key name and value) But this works: kamcmd htable.seti force_number a1234 1 Is there a way to escape this so i can use a number as element name?

Kamailio example configuration: auth section incomplete?
by George Diamantopoulos 02 Aug '17

02 Aug '17

Hello again, Still getting familiar with kamailio, and I'm wondering about the AUTH route in the example configuration file. Here's a reducted-simplified version of it for reference (from git master, without IP AUTH and comments): ______________________________________________ route[AUTH] { if (is_method("REGISTER") || from_uri==myself) { if (!auth_check("$fd", "subscriber", "1")) { auth_challenge("$fd", "0"); exit; } if(!is_method("REGISTER|PUBLISH")) consume_credentials(); } if (from_uri!=myself && uri!=myself) { sl_send_reply("403","Not relaying"); exit; } return; } ______________________________________________ So the way I see it, what happens is the following: * All REGISTERs will be challenged * All SIP messages with kamailio's aliases in the "From" header URI will be challenged * All SIP messages with no reference to kamailio's aliases in both R-URI and "From" header URI will be dropped The question is, what about messages that do not enter either of the two conditionals? For example, I expect the following to be very common: * Method: INVITE * R-URI: myself * From: username@"UAC's local IP address" (not myself) * To: myself So in the example above, the auth route will return without either having challenged or dropped the request, am I correct? This is because: * For the challenge: Method is not REGISTER and "From URI" is not one of kamailio host's aliases (cumulatively) * For dropping after sending 403: "From URI" is not one of kamailio's host's aliases (which calculates to true) but R-URI is "myself" So I'm guessing we're expecting the challenge to come from elsewhere in cases like the example above? Or is there something else I'm missing here? Thanks! BR, George

is_first_hop
by Nicolas Breuer 02 Aug '17

02 Aug '17

Hello, I tried to understand the concept of first hop in "replies" In the documentation ; For incoming SIP replies, it means that top Record-Route URI is 'myself' and source address is not matching it (to avoid detecting in case of local loops). Note that it does not detect spirals, which can have the condition for replies true also in the case of additional SIP reply receival. Here's an incoming reply received on 217.112.180.10. Via: SIP/2.0/UDP 217.112.180.10;branch=z9hG4bK723f.db3510ce15ac9bb6467e115ecc2fe2a7.0. Via: SIP/2.0/UDP 217.112.180.9;rport=5060;branch=z9hG4bK723f.741041093fec570744afcf44f2194581.0.

SIP Proxy/Redirect

02 Aug '17

Hi All, Hoping for some help as a beginner. I need to configure a sip proxy server so that it redirects all processes to a freeswitch server on another network. SIP UACs are on an isolated network and have only a connection to the sip proxy. All I need the proxy to do is pass on all requests to the the freeswitch UAS on a different network, as it will handle registering etc. Is there a basic setup for this type of behaviour? Many thanks, Aaron

Reverse DNS lookups inside Kamailio

T.38 fax, rtpproxy, re-invite
by Yu Boot 02 Aug '17

02 Aug '17

Hello. I'm using almost default kamailio.cfg with nathelper, rtpproxy, PSTN dialing and other default features. I have following scheme: FXS gateway -> (NAT) -> Kamailio -> FreeSwitch Voice calls work perfectly, no one-direction sound and so on. But with fax machine there was a problem. In wireshark I saw UDPTL from FS to Kamailio IP, and no UDPTL at all to FXS gw. I've guessed that something's wrong with a re-INVITE request processing in Kamailio. I've added this to WITHINDLG route: else if ( is_method("INVITE") ) { record_route(); } And problem was magically solved, T.38 now works OK. Is this OK solution or this may break something elsewhere? Thanks.

The goal is to detect if a 180 follow the 183.

Hi all, I use UAC module for remote registrations on my proxy box. There is no problem with incoming calls and I successfully register and receive calls. I have a Freeswitch box behind this proxy box and I want my proxy to add authorisation headers for outgoing calls transparently. I already have credentials at uacreg table for remote registrations. Is it possible use same credentials at uac_auth() function? Or should I run SQL to retrieve necessary fields to feed uac_auth? Thanks! /Volkan

MISSED COMPLETED 1 sip:1@abc.com sip:100@abc.com 2017-07-28 18:29:14 2017-07-28 18:29:14 yes no 2 sip:2@abc.com sip:100@abc.com 2017-07-28 18:29:14 2017-07-28 18:29:14 no yes 3 sip:3@abc.com sip:100@abc.com 2017-07-28 18:29:14 2017-07-28 18:29:14 no yes I have gone through various trace module, but its appear that all module record the call flow/logs in database. ie siptrace,acc,dialoge module. Could you please help me to log the information. one of the approach I have thought to store all the variable in AVP variables in request_route,failure_route,on_reply route..etc For ex. $avp(from)=$fu; $avp(to)=$tu; $avp(starttime)=startime $avp(endtime)=endtime etc... //log at call end in a seperate logs file and xlog("LOG_INFO",$avp(from),,$avp(to),$avp(starttime),$avp(endtime)) Please let know if this approach is correct or any other way to achieve this, Thanks, Amit

Weird issue with kamailio relaying messages to itself
by George Diamantopoulos 31 Jul '17

31 Jul '17

Hello all, I have been toying with kamailio lately, and I thought I had gotten to the point where I had a mostly working (tm) prototype. I gave it a test drive with some real calls, however, and an issue manifested at least once, where homer received packets originating from the kamailio host, and whose destination was also the kamailio host. The dialog this manifested in is a generally problematic one, with many retransmissions occurring because of slow database access (I haven't implemented htable caching yet). No packet capture over the network is actually taking place, I'm copying everything to homer with "trace_mode"set to 1. Homer shows these messages like in the screenshot: https://imagebin.ca/v/3VGJAmovRBmo. Here's an example of a packet: 2017-07-28 14:32:29 +0300 : 2.3.4.5:5060 -> 2.3.4.5:5060 INVITE sip:1234567890@kamailio-server.org SIP/2.0 Record-Route: <sip:2.3.4.5;lr;ftag=as491cec82> Via: SIP/2.0/UDP 2.3.4.5;branch=z9hG4bK0cf.07799e3eb71f33a9ef91178ac760ebd2.0 Via: SIP/2.0/UDP 2.3.4.5;branch=z9hG4bKsr-BnCVyrWoUladI14pU7Pry-Pzy-ONy-VSQ74NU7HzeYazq2nFU2Oc5FIWiGIKq-HXex1oONpam-C6IrIXkr4FQxZRh7sM Max-Forwards: 69 From: <sip:subscriber@5.4.3.2:5061>;tag=as491cec82 To: <sip:1234567890@kamailio-server.org> Contact: <sip:2.3.4.5;line=sr-eNC05xhKefQnON1EglFrOkF0OfpzV2s9UzM9UXMNQXMn5-B0Q-s*> Call-ID: 4e5d22c3369704b97d866c8d0f3798f8@192.168.201.2:5061 CSeq: 103 INVITE User-Agent: Asterisk PBX 11.13.1~dfsg-2~bpo70+1 Date: Fri, 28 Jul 2017 11:32:24 GMT Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE Supported: replaces, timer Remote-Party-ID: "9876543210" <sip:9876543210@192.168.201.2 >;party=calling;privacy=off;screen=yes Content-Type: application/sdp Content-Length: 500 v=0 o=root 242468242 242468243 IN IP4 172.17.130.13 s=Asterisk PBX 11.13.1~dfsg-2~bpo70+1 c=IN IP4 172.17.130.13 t=0 0 m=audio 59426 RTP/AVP 18 101 a=rtpmap:18 G729/8000 a=fmtp:18 annexb=no a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=ptime:50 a=sendrecv a=rtcp:59427 a=ice-ufrag:hffIoy6x a=ice-pwd:nXB8ip7Qz8ZG5yyZRr97kGJbej a=candidate:igct4zWHEzhGCjWc 1 UDP 2130706431 172.17.130.13 59426 typ host a=candidate:igct4zWHEzhGCjWc 2 UDP 2130706430 172.17.130.13 59427 typ host Can something like this be triggered by misconfiguration in the routing scripts? Should it worry me and should I dig into it more? Could it be a bug of the siptrace module and nothing bad actually took place? I'm not sure where to start with this, so any input would be greatly appreciated. Thanks!

Rate limiting
by NITESH BANSAL 31 Jul '17

31 Jul '17

Hello, I plan to add some rate limiting in the Kamailio. I'm already using Pike to rate limit based on the source IP. But in this case, i want to do the rate limiting per customer(regardless of the source IP), I can identify the customer based on a custom header in the INVITE, idea is to limit the customer to 'x' number of requests per second.

Configuration to use rtpengine for SRTP
by David Cunningham 31 Jul '17

31 Jul '17

Hello, We're configuring Kamailio 4.2 with rtpengine to act as a midpoint between a telephone using TLS/SRTP and Asterisk. There are examples out there for TLS/SRTP with WebRTC, but we're using a plain hard phone, not WebRTC. Would anyone be able to point us towards a Kamaiio configuration which: a) Tests if the destination phone (stored using usrloc) uses TLS. b) Sends RTP for calls to a TLS phone to rtpengine to be encrypted. We can assume all phones using TLS want to use SRTP. Thanks very much in advance. -- David Cunningham, Voisonics Limited http://voisonics.com/ USA: +1 213 221 1092 Australia: +61 (0) 2 8063 9019

why is tcp_no_connect disabled by default
by Vik Killa 27 Jul '17

27 Jul '17

I'm trying to understand the scenario when `tcp_no_connect` should ever be set to `no`. Kamailio comes with `tcp_no_connect=no` by default which means it will try (and seemingly always fail) to create an outbound tcp connection when a UAC's tcp connection is lost. This in-turn could start building up the tcp write queue and can be disastrous at scale. So why would this setting (`tcp_no_connect=no`) ever be useful? Thanks
