Hi Bogdan, I guess I'm confused as to why you say its being transmitted back to the same IP:Port:
U nat.ip:2370 -> opensips.ip:5060 U opensips.ip:5060 -> nat.ip:8427 Shouldn't it be going back to port 2370? And not 8427? -- James On Tue, Dec 7, 2010 at 2:43 AM, Bogdan-Andrei Iancu <bog...@voice-system.ro> wrote: > Hi James, > > From proxy point of view, everything looks ok - I see the reply sent back to > the exact IP:port where the request came from....So the reply should make it > through the NAT...But it seams it doesn't as the phone keeps retransmitting > the REGISTER.. > > Again, from NAT pov, opensips is doing the right stuff (doing symmetric > signalling) - there is nothing more you can do here for opensips..Maybe it > is something specific to the NAT device - any possibility to debug/trace on > it ? > > Regards, > Bogdan > > James Lamanna wrote: >> >> Hi, >> I was wondering if anyone had any experience getting a Cisco 7960 >> phone to register to opensips when the phone is behind a PIX firewall. >> I'm having a hell of a time getting it to register. >> I see these messages: >> >> U nat.ip:2260 -> opensips.ip:5060 >> REGISTER sip:opensips.ip SIP/2.0..Via: SIP/2.0/UDP >> 10.20.33.22:5060;branch=z9hG4bK48039e3a..From: < >> sip:xxxx...@opensips.ip;user=phone>..To: >> <sip:xxxxx...@opensips.ip;user=phone>..Call-ID: 0003 >> 6be7-b0aa0007-46220771-115f4...@10.20.33.22..date: Mon, 06 Dec 2010 >> 18:10:49 GMT..CSeq: 107 REGISTER >> ..User-Agent: CSCO/7..Contact: >> <sip:xxxxx...@10.20.33.22:5060>..Content-Length: 0..Expires: 45.... >> # >> U opensips.ip:5060 -> nat.ip:2260 >> SIP/2.0 401 Unauthorized..Via: SIP/2.0/UDP >> 10.20.33.22:5060;branch=z9hG4bK48039e3a;rport=2260;receiv >> ed=208.90.184.123..From: <sip:xxxxxx...@opensips.ip;user=phone>..To: >> <sip:xxxxx...@opensips.ip; >> user=phone>;tag=c5cd5e6c2a1d4c975e04c2ff1b643904.5bf3..Call-ID: >> 00036be7-b0aa0007-46220771-115f4fcc@ >> 10.20.33.22..CSeq: 107 REGISTER..WWW-Authenticate: Digest >> realm="asterisk", nonce="4cfd27fe0000780d7 >> 1826527370e7c8b97f663425df75489"..Server: OpenSIPS (1.6.3-notls >> (x86_64/linux))..Content-Length: 0.. >> .. >> # >> U nat.ip:2260 -> opensips.ip:5060 >> REGISTER sip:opensips.ip SIP/2.0..Via: SIP/2.0/UDP >> 10.20.33.22:5060;branch=z9hG4bK48039e3a..From: < >> sip:xxxxxx...@opensips.ip;user=phone>..To: >> <sip:xxxxx...@opensips.ip;user=phone>..Call-ID: 0003 >> 6be7-b0aa0007-46220771-115f4...@10.20.33.22..date: Mon, 06 Dec 2010 >> 18:10:49 GMT..CSeq: 107 REGISTER >> ..User-Agent: CSCO/7..Contact: >> <sip:xxxxxx...@10.20.33.22:5060>..Content-Length: 0..Expires: 45.... >> # >> U opensips.ip:5060 -> nat.ip:2260 >> SIP/2.0 401 Unauthorized..Via: SIP/2.0/UDP >> 10.20.33.22:5060;branch=z9hG4bK48039e3a;rport=2260;receiv >> ed=208.90.184.123..From: <sip:xxxxx...@opensips.ip;user=phone>..To: >> <sip:xxxxxx...@opensips.ip; >> user=phone>;tag=c5cd5e6c2a1d4c975e04c2ff1b643904.5bf3..Call-ID: >> 00036be7-b0aa0007-46220771-115f4fcc@ >> 10.20.33.22..CSeq: 107 REGISTER..WWW-Authenticate: Digest >> realm="asterisk", nonce="4cfd28000000780e5 >> c3381d838a044479357aa6c660df432"..Server: OpenSIPS (1.6.3-notls >> (x86_64/linux))..Content-Length: 0.. >> >> This suggests the 401 response is not making it back to the >> phone....but I'm not sure why the PIX would be blocking it. >> All sip fixup is off. >> >> Any configuration suggestions would be much appreciated. >> The phone has: >> nat_enable: 0 >> nat_received_processing: 0 >> >> That was the only way I could get opensips to send the responses back >> to the correct port. >> >> Thanks. >> >> -- James >> >> _______________________________________________ >> Users mailing list >> Users@lists.opensips.org >> http://lists.opensips.org/cgi-bin/mailman/listinfo/users >> >> > > > -- > Bogdan-Andrei Iancu > OpenSIPS Bootcamp > 15 - 19 November 2010, Edison, New Jersey, USA > www.voice-system.ro > > > _______________________________________________ > Users mailing list > Users@lists.opensips.org > http://lists.opensips.org/cgi-bin/mailman/listinfo/users > _______________________________________________ Users mailing list Users@lists.opensips.org http://lists.opensips.org/cgi-bin/mailman/listinfo/users
