Hi all, I need help configuring a little bit complex NAT/PAT scenario. Idea is that clients on Internet registers themselvs against kamailio and then it routes requests to Alcatel PBX. kamailio acts also as NAT proxy ( so that clients on internet does not need vpn connection. Something like EDGE SERVER for MS Lync clients) Below the scenario Alcatel PBX: 10.9.6.3 Kamailio internal NIC: 172.16.52.240 Kamailio DMZ NIC: 10.9.23.180 PU.BL.I.C.IP: 1.2.3.4 ALCATEL PBX(LAN 10.9.6.3)————-------------- | |———-(LAN INT 172.16.52.240) | |KAMAILIO (2 NICs) ———————————— | | | | |————(LAN dmz 10.9.23.180) PAT/NAT | |————firewal | | PU.BL.I.C.IP ^ | | Client on internet As you can see there is a firewall that make NAT and PAT from PU.BL.I.C.IP to internal Kamailio DMZ nic. natted ports are 5060 and range from 30000 to 65000 ( for RTP ) I'am tryng to use kamailio.cfg that comes with installation.. Now I am making some changes but is not working. Internal client ( lan 172.16.52.x ), registered on kamailio, can make call to alcatel phones and viceversa. External client ( on internet ) can register to kamailio but cannot call alcatel phone nor client registered on kamailio. Here some traces CALL FROM EXTERNAL CLIENT TO INTERNAL CLIENT: *U 2014/07/25 11:26:55.709196 2.2.2.2:39464 -> 10.9.23.180:5060 INVITE sip:1001@lwsbc.longwave.eu SIP/2.0.

sdpops and rtpproxy/rtpengine

by Alex Balashov

Hi, Is it safe to use sdpops and the rtpproxy* modules together, given that the latter modify SDP? In other words, can I prune some codecs first, and then call rtpproxy_offer()? Is it safe? Thanks, -- 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

SDPOPS issue or append_hf

by Igor Potjevlesch

Hello, I have an issue with the module SDPOPS while using "sdp_keep_codecs_by_name". If the calling party sends only one codec description like: Content-Type: application/sdp Content-Length: 202 v=0 o=UserA 2966746938 1790378070 IN IP4 10.141.0.21 s=Session SDP c=IN IP4 10.141.0.21 t=0 0 m=audio 49152 RTP/AVP 8 101 a=rtpmap:8 PCMA/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 The result of the function "sdp_keep_codecs_by_name("PCMA,PCMU,G729a");" is: Content-Type: application/sdp Content-Length: 170 P-Asserted-Identity: "+0123456789" <sip:+0123456789@sip.tld> v=0 o=UserA 2485672881 3000549892 IN IP4 a.b.c.d s=Session SDP c=IN IP4 a.b.c.d t=0 0 m=audio 40330 RTP/AVP 8 a=rtpmap:8 PCMA/8000 a=nortpproxy:yes If I open the capture in Wireshark, the PAI is not in the SDP part, and the end of the capture after "a=rtpmap:8 PCMA/8000" is seen as "Data (18 bytes)". I don't understand why the PAI is inserted within the SDP part. Adding the PAI is done after "sdp_keep_codecs_by_name": if (!is_present_hf("P-Asserted-Identity")) { $var(pai) = $(fU{re.subst,/^0/+33/g}); append_hf("P-Asserted-Identity: \"$var(pai)\" <sip:$var(pai)@$fd>\r\n"); } I guess that this cause my INVITE being dropped by 488 Media Not Acceptable Here.

planning the release of v4.1.5

by Daniel-Constantin Mierla

Hello, I am considering to release v4.1.5 sometime next week, most likely on the 6th of August. Checking the 4.1 branch, there are not many fixes, few are on my list for backporting. That's good, indicating a high level of stability. If anyone is aware of issues not reported on tracker or patches that have not been backported, add to the tracker or write a message to sr-dev mailing list. Cheers, Daniel -- Daniel-Constantin Mierla - http://www.asipto.com http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda

Kamailio with open ims

by Senthil K

Hi All, i have a query here, the user is registered with the open IMS and also with Kamailio ( as a third party registration via SCSCF ) Here my issue is ; when the user makes a call, the INVITE reaches to kamailio from SCSCF( Scscf port is 6060) , when the Kamailio sends the INVITE back to IMS, it sends to the port 5060. problem is , the kamailio registers the SCSCF port as 6060, but when sending the INVITE back it uses the port 5060. why this is So ?? i checked in registered entry as well, it shows that the contact is SCSCF with 6060 port only. please help in this situation, Kind regards SenthilK

Kamailio with rtpproxy-ng and mediaproxy-ng: Error rewriting SDP

by Olli Heiskanen

Hello, I've been experimenting with Kamailio with ws and sip clients and could need a hand in getting a call between those two to work. I have Kamailio 4.1.2 (using rtpproxy-ng instead of rtpproxy) on a CentOS 6.5 and a mediaproxy-ng running. I have clients wsclient(a)testers.com and gsclient(a)testers.com and I try to make call from wsclient to gsclient. The wsclient is a jssip client running on chrome and gsclient is a grandstream desk phone. My config file is the default one enhanced by online examples. I use a html5 <audio> element for the media streams, and configured my jssip phone to accept audio options like this: var options = { 'eventHandlers': eventHandlers, 'mediaConstraints': {'audio': true, 'video': false } }; sipUA.call(callto, options); I used the instructions from here: http://www.slideshare.net/crocodilertc/webrtc-websockets What I get is gsclient ringing, and as I answer there is no audio and call hangs up in a few seconds. I guess this is a SDP problem, something between Kamailio and Mediaproxy-ng but SDP is not my strong point so I'd appreciate advice. Question is where's my misconfiguration/problem? I would like to learn why this problem occurs and how to fix it rather than getting a solution right away, but please bear in mind I don't know much about SDP. In Kamailio log I see: kamailio[27059]: ERROR: rtpproxy-ng [rtpproxy.c:1346]: rtpp_function_call(): proxy replied with error: Error rewriting SDP kamailio[27058]: ERROR: rtpproxy-ng [rtpproxy.c:1346]: rtpp_function_call(): proxy replied with error: Unknown call-id kamailio[27057]: ERROR: rtpproxy-ng [rtpproxy.c:1346]: rtpp_function_call(): proxy replied with error: Unknown call-id Following are the INVITEs and 200 OKs from my SIP trace (1.1.1.1 is the ip of my Kamailio & mediaproxy-ng box and 2.2.2.2 is the public ip behind which both my clients are).

no fork mode and more than one listen address found (will use only the first one)

by Yuriy Gorlichenko

Hello. I Installed kamailio 4.1.4, when I starting my server I see following Warning no fork mode and more than one listen address found (will use only the first one) So I see only first listening port at my netstat At my kamailio.cfg file I write fork=yes? but it not helps me. I found the same issue at this mailing list http://comments.gmane.org/gmane.comp.voip.openser.user/10686 But it very old issue (2007 year) and I think patch at this issue does not help me. How I can start my Server for runnings with many interfaces?

Understanding DNS resolution done by Kamailio

by Igor Potjevlesch

Hello, I'm using Kamailio 4.1 and I'm wondering how to avoid external DNS resolution. I have the following config: dns_cache_init=no use_dns_cache=no dns=no rev_dns=no Even with this config, I have many and many DNS query on SRV _sip for the hostnames set in carrierroute module. These requests are not useful because the A resolution is done by /etc/hosts. Major problem with this, is that when I have a DNS issue or IP transit issue, Kamailio waits for resolution timeout and becomes overloaded. As a consequence, Kamailio can't treat others SIP requests like REGISTER because he stuck in DNS resolution. Regards, Igor.
