[Kamailio-Users] Kamailio -> Asterisk Redirect/Reinvite and Remote-Party-ID

by Florian Meister

Hi, basically I'm using this structure at the moment: SIP Users <----> Kamailio <-----> Asterisk <-----> PSTN I have to add a diversion-functionality at kamailio-level, so to simply rewrite $ru with something else defined in the database. That's working without problems. For billing issues, I also have to add a Remote-Party-ID header, set to the SIP user, which initiated the redirect in the database. Now to the problem: When a call is coming from PSTN, it's passing the asterisk server, then at kamailio level $ru is rewritten and sent back to asterisk (I'm talking about a redirect to a number in PSTN here) What I've seen from the logs is, that asterisk is seeing that it gets an invite back with the same call-id, and therefore it cancels the original invite and handles the whole call internally via the Local Channel. The Problem is, that in the invite sent from kamailio back to asterisk, I've set a Remote-Party-ID header to tell asterisk to set the Callerid correctly for billing purposes. Now it seems that asterisk is _ignoring_ this header from the second invite. So is this an expected behavior ? If yes, how to do it correctly ? Below you can see the verbose output of asterisk. Since the call is handled at "Local" Channels the function to read sip headers does not work. The only message I get is "thanks to SIP/tpsiptestproxyu01-00d0a0b8". -- Called tpsiptestproxyu01/+435572949012 -- Now forwarding DAHDI/2-1 to 'Local/066480588134@from-internal' (thanks to SIP/tpsiptestproxyu01-00d0a0b8) -- Executing [066480588134@from-internal:1] NoOp("Local/066480588134@from-internal-d69e;2", "435572501134") in new stack [Dec 1 15:14:50] WARNING[20506]: chan_sip.c:15797 func_header_read: This function can only be used on SIP channels. -- Executing [066480588134@from-internal:2] NoOp("Local/066480588134@from-internal-d69e;2", "") in new stack -- Executing [066480588134@from-internal:3] Dial("Local/066480588134@from-internal-d69e;2", "DAHDI/G0/066480588134") in new stack -- Requested transfer capability: 0x00 - SPEECH -- Called G0/066480588134 -- DAHDI/124-1 is proceeding passing it to Local/066480588134@from-internal-d69e;2 -- Local/066480588134@from-internal-d69e;1 is proceeding passing it to DAHDI/2-1 In the SIP debug you can see that asterisk is cancelling the dialog with kamailio and doing it itself: 13:49:30.589054 IP [--ASTERISK--].5060 > [--KAMAILIO--].5060: SIP, length: 938 E.......@..L..,L..,N........INVITE sip:+435572949012@[--KAMAILIO--] SIP/2.0 Via: SIP/2.0/UDP [--ASTERISK--]:5060;branch=z9hG4bK5629d66b;rport Max-Forwards: 70 From: "435572501134" <sip:435572501134@[--ASTERISK--]>;tag=as27658014 To: <sip:+435572949012@[--KAMAILIO--]> Contact: <sip:435572501134@[--ASTERISK--]> Call-ID: 4bbee84339a9e2d30850185317983625@[--ASTERISK--] CSeq: 102 INVITE User-Agent: Asterisk PBX 1.6.1.5 Remote-Party-ID: "435572501134" <sip:435572501134@[--ASTERISK--]>;privacy=off;screen=yes Date: Tue, 01 Dec 2009 12:49:30 GMT Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO Supported: replaces, timer Content-Type: application/sdp Content-Length: 263 v=0 o=root 930830518 930830518 IN IP4 [--ASTERISK--] s=Asterisk PBX 1.6.1.5 c=IN IP4 [--ASTERISK--] t=0 0 m=audio 16924 RTP/AVP 8 101 a=rtpmap:8 PCMA/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=silenceSupp:off - - - - a=ptime:20 a=sendrecv 13:49:30.591037 IP [--KAMAILIO--].5060 > [--ASTERISK--].5060: SIP, length: 342 E..r..@.@.[0..,N..,L.....^.aSIP/2.0 100 Trying Via: SIP/2.0/UDP [--ASTERISK--]:5060;branch=z9hG4bK5629d66b;rport=5060 From: "435572501134" <sip:435572501134@[--ASTERISK--]>;tag=as27658014 To: <sip:+435572949012@[--KAMAILIO--]> Call-ID: 4bbee84339a9e2d30850185317983625@[--ASTERISK--] CSeq: 102 INVITE Server: OpenSER (1.3.2-notls (x86_64/linux)) Content-Length: 0 13:49:30.594345 IP [--KAMAILIO--].5060 > [--ASTERISK--].5060: SIP, length: 1093 E..a..@.@.XA..,N..,L.....M+LINVITE sip:066480588134@[--ASTERISK--]:5060;transport=udp SIP/2.0 Record-Route: <sip:[--KAMAILIO--];lr;ftag=as27658014> Via: SIP/2.0/UDP [--KAMAILIO--];branch=z9hG4bK06.05390227.0 Via: SIP/2.0/UDP [--ASTERISK--]:5060;branch=z9hG4bK5629d66b;rport=5060 Max-Forwards: 69 From: "435572501134" <sip:435572501134@[--ASTERISK--]>;tag=as27658014 To: <sip:+435572949012@[--KAMAILIO--]> Contact: <sip:435572501134@[--ASTERISK--]> Call-ID: 4bbee84339a9e2d30850185317983625@[--ASTERISK--] CSeq: 102 INVITE User-Agent: Asterisk PBX 1.6.1.5 Date: Tue, 01 Dec 2009 12:49:30 GMT Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO Supported: replaces, timer Content-Type: application/sdp Content-Length: 263 Remote-Party-ID: "435572949012" <sip:435572949012@tpseru01.tele.net>;party=caller;privacy=none;screen=yes v=0 o=root 930830518 930830518 IN IP4 [--ASTERISK--] s=Asterisk PBX 1.6.1.5 c=IN IP4 [--ASTERISK--] t=0 0 m=audio 16924 RTP/AVP 8 101 a=rtpmap:8 PCMA/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=silenceSupp:off - - - - a=ptime:20 a=sendrecv 13:49:30.594605 IP [--ASTERISK--].5060 > [--KAMAILIO--].5060: SIP, length: 460 E.......@..)..,L..,N.......

[Kamailio-Users] client registers with private IP

by Joao Gomes Pereira

Hello I'm trying to register in Kamailio, an Asterisk working behind Nat. Here is the trunk: The problem is: Asterisk is registering with its internal IP (192.168.1.25), as you can see here: sip:s@192.168.1.25 Q= Expires:: 81 Callid:: 480b40aa13ddd8707787b21a69656535(a)127.0.0.1 Cseq:: 103 User-agent:: Asterisk PBX How can I force Asterisk to register with its public IP? Is there some configuration I can do in Kamailio? Thanks Regards Joao Pereira -- StarTel - A Rede Livre Joao Gomes Pereira www.startel.pt +351 304500650 sip: gomespereira(a)startel.pt

Hi List, Apologies if you get this twice, for some reason the last post didn't seem to appear on the list.. I am running Debian lenny. Can I just change the repos in sources.list from lenny to testing and unstable to get the correct python dependencies etc for the ag-project tools? Thanks, Brian
