Video recording with RTPENGINE
by Alberto Llamas 24 Apr '17

24 Apr '17

Hi guys, Any of you have experience using the '*start_recording()*' function of the RTPENGINE in a WebRTC scenario?. At this point, I am able to record the stream but I am not able to play them. The output is a .pcap file in a raw format. I have tried the conversion: raw -> H264 -> mp4/avi (with different tools: videosnarf, x264, ffmepg) and not luck. Do you know the right way to convert those stream in raw format?. Any hint will be appreciated. Regards,

MSRP Connection is not working
by Jegadeesan 24 Apr '17

24 Apr '17

Hi , I'm very new to Kamailio application and trying to setup the test environment for Android RCS client (https://github.com/android-rcs/rcsjta). Parallelly we have deployed the Kamailio on ECS2 and able to make a call/text using any other sip clients. Apparently, we had enabled the MSRP modules over TCP and tried to test with Android RCS. But getting stuck at the connecting screen. Although we could see SIP exchange logs between two clients. Can anyone help me in fixing this issue? -- Jegadeesan M

Kamailio not forwarding call
by Gonzalo Gasca Meza 22 Apr '17

22 Apr '17

Hi all, I worked in an prototype recently where I *had* the following setup working. Kamailio is using Postgres to forward the call to Twilio domain. *Topology:* SIP client (tls) > (SIP Provider) > (tls) Kamailio (udp) > Twilio > IVR Right now when I call from SIP Client to IVR, call is not forwarded. Nothing has changed on Kamailio side. *Troubleshooting:* a) *SIP client (tls) > (SIP Provider) > (tls) Kamailio (udp) > Twilio > IVR [Fails]* - Case described above. b) *Call from PSTN > (SIP Provider) > (tls) Kamailio (udp) > Twilio > IVR [Works]* I debug and call arrives to Kamailio but is not being forwarded to Twilio. This used to work before. When call works Kamailio seems to find remote domain, when fails we just sent a *502 Bad Gateway* message Twilio does not support DNS SRV records, just A host resolution. *Logs* While looking at debugs I found that this DNS logs: Pastebin below: *Call fails <https://pastebin.com/ttkK1Kkd> * Apr 22 06:37:00 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28476]: DEBUG: <core> [dns_cache.c:537]: _dns_hash_find(): (_sip._ udp.parzee.sip.twilio.com(31), 33), h=816 Apr 22 06:37:00 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28476]: DEBUG: <core> [resolve.c:741]: get_record(): lookup(_sip._ udp.parzee.sip.twilio.com, 33) failed Apr 22 06:37:00 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28476]: DEBUG: <core> [dns_cache.c:864]: dns_cache_mk_bad_entry(): (_sip._ udp.parzee.sip.twilio.com, 33, 60, 1) Apr 22 06:37:00 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28476]: DEBUG: <core> [dns_cache.c:798]: dns_cache_add(): adding _sip._ udp.parzee.sip.twilio.com(31) 33 (flags=1) at 816 Apr 22 06:37:00 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28476]: DEBUG: <core> [dns_cache.c:537]: _dns_hash_find(): (parzee.sip.twilio.com(21), 1), h=267 Apr 22 06:37:00 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28476]: DEBUG: <core> [resolve.c:937]: get_record(): skipping 0 NS (p=0xa1d2e7, end=0xa1d2e7) Apr 22 06:37:00 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28476]: DEBUG: <core> [resolve.c:952]: get_record(): parsing 0 ARs (p=0xa1d2e7, end=0xa1d2e7) Apr 22 06:37:00 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28476]: DEBUG: <core> [dns_cache.c:1741]: dns_get_related(): (0x7f1b5c227920 ( parzee.sip.twilio.com, 1), 1, *(nil)) (0) Apr 22 06:37:00 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28476]: DEBUG: <core> [dns_cache.c:840]: dns_cache_add_unsafe(): adding parzee.sip.twilio.com(21) 1 (flags=0) at 267 *Call works <https://pastebin.com/AkWsvFVA>* Apr 22 07:00:03 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28481]: DEBUG: <core> [dns_cache.c:537]: _dns_hash_find(): (_sip._ udp.parzee.sip.twilio.com(31), 33), h=816 Apr 22 07:00:03 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28481]: DEBUG: <core> [resolve.c:741]: get_record(): lookup(_sip._ udp.parzee.sip.twilio.com, 33) failed Apr 22 07:00:03 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28481]: DEBUG: <core> [dns_cache.c:864]: dns_cache_mk_bad_entry(): (_sip._ udp.parzee.sip.twilio.com, 33, 60, 1) Apr 22 07:00:03 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28481]: DEBUG: <core> [dns_cache.c:798]: dns_cache_add(): adding _sip._ udp.parzee.sip.twilio.com(31) 33 (flags=1) at 816 Apr 22 07:00:03 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28481]: DEBUG: <core> [dns_cache.c:537]: _dns_hash_find(): (parzee.sip.twilio.com(21), 1), h=267 Apr 22 07:00:03 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28481]: DEBUG: <core> [msg_translator.c:2876]: create_via_hf(): id added: <;i=7>, rcv proto=3 Apr 22 07:00:03 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28481]: DEBUG: <core> [msg_translator.c:158]: check_via_address(): (54.172.60.0, 54.172.60.0, 0) Apr 22 07:00:03 parzee-sip-kamailio1 /usr/local/sbin/kamailio[28481]: DEBUG: tm [t_funcs.c:368]: t_relay_to(): SER: new transaction fwd'ed Thank you!

Kamailio rtpengine sdp
by gerry kernan 21 Apr '17

21 Apr '17

Hi Thanks in advance if anyone can point me in the correct direction . I have kamailio running in front of some asterisk VM's. SIP endpoint register to their asterisk PBX via Kamailio dispatcher module. I'm running rtpengine with a Wan and private interface to bridge audio stream between these endpoints on the WAN to asterisk PBX running on LAN IP behind Kamailio. Calls from ext to ext work fine audio both directions , calls outbound to PSTN via SIP trunk to SIP provider via trunk on asterisk work fine audio both directions. But incoming calls via SIP provider I only get audio on stream from asterisk registered ext to external caller , no audio from external caller to the asterisk ext. I reckon I have something wrong in my Kamailio.cfg . if I register an ext direct to asterisk I get audio both ways on incoming calls. And rtp logs from rtpenegine show it as trying to send the rtp to the private address of the sip endpoint rather that its WAN address. I think my mistake in somewhere in the cfg below. Do I need to handle invites from the backend asterisk servers different that invites from sip endpoints?

NOTIFY request from PCSCF is on TCP transport rather than UDP
by Haggerty, Paul (phaggert) 21 Apr '17

21 Apr '17

Hello, I've got an IMS client which uses UDP for transport. Our application server is also using UDP. We are using a Kamailio IMS Core. The client REGISTERS with UDP and also does a SUBSCRIBE. Our application server responds with a NOTIFY to the client. Looking at the trace. The messages between the PCSCF and SCSCF are TCP. The REGISTER and SUBSCRIBE responses to the client from the PCSCF are UDP (which I would expect). However, when the PCSCF get the NOTIFY is tries to open a TCP connection to the Client. (I assume to send a NOTIFY). Any ideas of what is happening here? I'm fairly new to the Kamailio IMS. I am more familiar with the Open IMS Core. (which is not having this issue). Thanks, Paul
