Hello, We are trying to use Kamailio 4.2 with RTPEngine 3.3 behind NAT. Somehow SIP responses (200 OK) are not handled by Kamailio. The following INVITE is send to the receiving end (WebRTC Client): INVITE sip:evQzk4l62MdF3G7U6eudj@whtest3.24dial.com SIP/2.0 Record-Route: <sip:104.155.11.255:5060;nat=yes;lr=on> Via: SIP/2.0/UDP 104.155.11.255:5060 ;branch=z9hG4bK865.9db0c023bec2f314e89ae0f18b78d2f0.0 Via: SIP/2.0/UDP 10.240.215.73:5060 ;rport=5060;received=146.148.113.245;branch=z9hG4bK644600e2 Max-Forwards: 69 From: "Anonymous" <sip:anonymous@anonymous.invalid>;tag=as68f0a26a To: <sip:evQzk4l62MdF3G7U6eudj@whtest3.24dial.com> Contact: <sip:anonymous@10.240.215.73:5060;alias=146.148.113.245~5060~1> Call-ID: 368f6ec901a3552e3b37a70907634f4f@10.240.215.73:5060 CSeq: 102 INVITE User-Agent: Asterisk PBX 12.5.0 Date: Fri, 24 Oct 2014 08:38:09 GMT Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE Supported: replaces, timer Content-Type: application/sdp Content-Length: 738 P-hint: outbound .......

I have a xlog call as the first statement in kamailio routing script. I can see the request, which get's handled correctly but the response does not appear in kamailio log, though it arrives at the machine. I am totally helpless, what might be wrong. If we use kamailio on a public accessable machine everything works as expected. Maybe anyone might have had similiar problems using kamailio behind NAT. Kind regards, Marko

RPM Based installs...

by Derrick Bradbury

Just a question for the RPM maintainers... Is there a reason for some of the modules (such as carrierroute) not being included in the RPMS? It's been bugging me for a while, when I do an installation, I have to go and compile all the sources .... Not that it's an issue, just easier to do it from RPM if available. Thanks! Derrick

Kamailio Infront of Asterisk with remote PBX

by Kenny Watson

Hi, I have a few asterisk servers providing some basic SIP trunking and routing. We have remote PBXs trunked onto asterisk which calls come into asterisk and are routing down to extensions on the remote PBX via prefix routing. I'm looking to have a central Kamailio Registrar/Proxy/Loadbalancer which Invites come into and are routed out to either SIP phones which are registered or to the remote PBX. I'm looking for some advice as to which modules would be best to use to achieve this as the remote PBXs will be dynamically registered rather than fixed gateways. Please let me know what further information would be helpful. Thanks Kenny Watson

async workers

by Alex Balashov

Hi, What is the practical limit to the number of async worker processes? With SIP child processes, it seems to be about the number of available CPUs in /proc/cpuinfo. After that--at least, per my testing--one begins to hit the point of diminishing returns, presumably due to SHM IPC and synchronisation issues. Is the restriction similar in the async execution context? -- Alex Balashov - Principal Evariste Systems LLC Tel: +1-678-954-0670 Web: http://www.evaristesys.com/, http://www.alexbalashov.com/ Please be kind to the English language: http://www.entrepreneur.com/article/232906

Crash after async_sleep().

by Vitaliy Aleksandrov

Hello list. root@proxy:/# kamcmd core.version kamailio 4.1.4 (i386/linux) I'm getting a crash when I'm trying to simulate a ringing UAS from kamailio config. To achieve this I've added the next config actions: > if (is_method("INVITE") && !has_totag() && $rU =~ "^999") { > sl_send_reply("100", "Fake Trying"); > sl_send_reply("180", "Fake Ringing"); > > t_set_fr(120000, 120000); > t_set_retr(65000, 65000); > t_set_auto_inv_100(0); > > async_sleep("60"); > send_reply("480", "Fake Temporary Unavailable"); > > t_release(); #<--- > > exit(); > }; I expect to receive 180 reply immediately and 480 after 60 seconds. The problem appears when a caller cancels a call after 60 seconds which is equal to async_sleep() wait time. I suppose there is a race condition happens between UDP worker that processes CANCEL request and timer process which calls t_continue() (tm's function). Calling t_newtran() explicitly doesn't change the situation. The only way I found to avoid crash is to remove t_release() call. In this case kamailio complains that "script write didn't release transaction" but continues to process new calls. With -DTIMER_DEBUG and -DDBG_QM_MALLOC I got next information: /usr/sbin/kamailio[11307]: : <core> [mem/q_malloc.c:468]: qm_free(): BUG: qm_free: freeing already freed pointer (0xb1d8c520), called from tm: h_table.c: free_cell(178), first free tm: h_table.c: free_cell(157) - aborting Crash mostly happens because of broken circular list of timers (timer_ln->next == NULL), but one time I saw got abort() during CANCEL request processing when tm tried to call free_cell() for an already freed pointer.

It works perfectly within local network. In public network the signaling establishes perfectly, but most of the time we hear no voice, sometimes we hear one sided voice and in rare cases we hear voice from both sides. To fix this issue we configured our nathandler like the below: But, still no luck. Any idea how to fix this?

Kamailio behind NAT (Asterisk - Kamailio - RTPEngine - Browser)

by Marko Seidenglanz

Hello, I have a problem with the following configuration. I want to make calls from Asterisk to a browser using RTPEngine as relay. Everything works fine, if Kamailio is not natted (See kamailio_without_nat.log). If it's address is translated, then 200 OK responses from the browser don't seem to be received by kamailio.
