Using a second Perl library
by David Cunningham 04 May '23

04 May '23

Hello, We are using a product which already uses the "app_perl" module and sets the "filename" parameter to its own Perl library. However, we want to add more Perl code without having to modify that product's library. Does anyone know of a way to do this? To have Kamailio use Perl code from two different places? I guess in the worst case scenario we could use "app_python3", and have some Python code call subprocess.run() on the Perl code. Thanks very much, -- David Cunningham, Voisonics … [View More]

Development is open for future release of v5.8.x series
by Daniel-Constantin Mierla 04 May '23

04 May '23

Hello, the branch 5.7 was created, therefore the master branch is open for adding new features, to be part of future release series v5.8.x (or whatever version is decided for next series). Any bug fix committed to master that applies to 5.7.x or older stable branches should be backported as usual with "git cherry-pick -x ..." to appropriate branches like 5.7 or 5.6. Expect that v5.7.0 will be released in a few weeks from now. Based on the workflow used during the past years, the next future … [View More]

send reply from branch route?
by Benoit Panizzon 04 May '23

04 May '23

Hello Is there a possibility to send a reply from within a branch route? Experimental case (yes, I know it's a non working set-up, but I just wonder if that would be possible). Two registrar nodes, location information shared between the two. CPE registers via TLS, therefore the existing connection shall be used towards the CPE and that only exists on one of the registrars. So in the Branch Route I would like to do something like: $var(socket) = $(ulc(aor=>socket)[$T_branch_idx]); if (… [View More]

Branching 5.7 on git repo for 5.7.x releases
by Daniel-Constantin Mierla 04 May '23

04 May '23

Hello, I am planning to split 5.7.x series on its own git branch 5.7 on Thursday, May 4, 2023. After that, master branch will be open for new features (to become part of 5.8 or what ever version will be decided to be next). Usually testing should continue for branch 5.7 for another 1-2 weeks, then, if no relevant road blockers pop up, we should release 5.7.0 as first stable version in the 5.7.x series.

Kamailio - asterisk - ACK
by Péter Dr. Barabás 03 May '23

03 May '23

Hi all, we are developing a softphone mobile application which registers to asterisk through kamailio. Kamailo proxies the request to asterisk and replies from asterisk to the clients. Registration works fine with asterisk authentication. The problem appears in the following flow: 1. Mobile client A calls client B. 2. Asterisk gets INVITE through kamailo, sends back 401, and get INVITE with credentials. 3. Asterisk sends invite to client B towards kamailio. 4. Kamailio forwards … [View More]

RFC: selective backports to latest stable as a dedicated git branch

Hello, during past on-site/online devel meetings as well as on mailing lists or tracker, there were various discussions around the idea or requests to make new features available quicker to stable branches. Of course, one can do local git cherry-picking, but I thought to bring this in discussion and see if makes sense to get something more coordinated between developers and community. Therefore I am cross-posting to sr-dev and sr-users to see if there is interest for it from both communities. … [View More]

Clarification of 'return false' behaviour

Hi list, Hope you are all well! I'm using Kamailio version 5.6.4 (installed from the repo rpm.kamailio.org/centos/7) and noticed that every route that uses "return false" is exiting the script, instead of returning.... This was not the case on version 5.4.6 as the same script is running fine..... From this page https://www.kamailio.org/wikidocs/tutorials/faq/main/#how-is-the-function-r…, I would think that when a route returns false, it would return -1 and not stop execution, since negative is … [View More]

rtpengine module: sdp offer in message reply, ip protocol version not passed to rtpengine?
by Benoit Panizzon 02 May '23

Hi Team I think, I might have found something that was overseen in the rtpengine module. A (ipv6) <=> rtpengine <=> B (ipv4) Invite+SDP from B to A It looks like this works as expected. A SDP c= line is created containing an ipv6 address. Invite, no SDP from A to B Reply with SDP offer from B to A The information about A being reachable via ipv6 and therefore an ipv6 c= line being required, could be taken from the via header of the reply. But am I right to fear, that the … [View More]

Route Header based routing for initial INVITE
by harneet singh 28 Apr '23

Hi Experts, I believe the loose_route() in kamailio can be used for initial Out of the dialog INVITE processing as well. Is that the correct understanding? If so, the request will be forwarded ahead to the destination corresponding to the Route Header remaining (if any) after Kamailio has stripped off it's own Address(es) from the Route Header(s). Is that correct? Regards, Harneet Singh -- "Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth" - … [View More]

Strange RTCP issue
by Kiss Zoltán 27 Apr '23

27 Apr '23

Hello, We have a transparent proxy in front of Asterisk boxes. The media is handled by rtpengine, and the "manage" work is done by Kamailio in the route[NATMANAGE] section like this: if(nat_uac_test("8")) { # Packet from backend server if(ds_is_from_list()){ if (rtpengine_manage("replace-origin replace-session-connection direction=internal direction=pub")) { xdbg("NATMANAGE --- Success rtpengine_manage() RTP … [View More]from INTERNAL to EXTERNAL $ru"); } } else { if (rtpengine_manage("replace-origin replace-session-connection direction=pub direction=internal")) { xdbg("NATMANAGE --- Success rtpengine_manage() RTP from EXTERNAL to INTERNAL $ru"); } } } else { # Packet from backend server if(ds_is_from_list()){ if (rtpengine_manage("replace-origin replace-session-connection trust-address direction=internal direction=pub")) { xdbg("NATMANAGE --- Success rtpengine_manage() RTP from INTERNAL to EXTERNAL $ru"); } } else { if (rtpengine_manage("replace-origin replace-session-connection trust-address direction=pub direction=internal")) { xdbg("NATMANAGE --- Success rtpengine_manage() RTP from EXTERNAL to INTERNAL $ru"); } } } Everything is working fine, but with some clients (like Grandstream phone) the RTCP session wants to go tot he private address of the phone. Here is the log of one of these strange calls: Apr 27 16:54:38 rtp1 rtpengine[2273]: INFO: [312ed76c31f21b71452e91e5184ad25b@172.16.2.210:5060]: [core] --------- Port 178.238.213.14:11088 <> 81.183.216.3:5068 , SSRC 77c19488, 625 p, 107500 b, 0 e, 29 ts Apr 27 16:54:38 rtp1 rtpengine[2273]: INFO: [312ed76c31f21b71452e91e5184ad25b@172.16.2.210:5060]: [core] --------- Port 178.238.213.14:11089 <> 10.0.5.192:5069 (RTCP), SSRC 0, 0 p, 0 b, 0 e, 43 ts As you can see the RTP itself is okay, but the RTCP will somehow go to the private address. If we tracing the sdp messages in sngrep, then we can see that Kamailio transforming IP addresses for the backend servers to the public (and the private address of the rtpengine) addresses. We are missing something? Thank you! With kind regards, Zoltan [View Less]

Hi Experts, We have been using Kamailio as a sip proxy for a fair bit of time now(version 5.3.2 though) and do understand the native routing mechanism that can be instrumented through the kamailio cfg scripts. We initially had only two sides, where the traffic could come from into Kamailio and it just passed through to the other side(ie Traffic from A was routed to B and that from B was routed to A). Off late, a few more sip elements have been introduced in the deployment and now there is a … [View More]
