Also, using firmware 2.11 (latest) I could not get the m3 to register showing the privcontact address.
I "think" the privcontact address is "all important". ============================ Tony Graziano, Manager Telephone: 434.984.8430 Fax: 434.984.8431 Email: [email protected] LAN/Telephony/Security and Control Systems Helpdesk: Telephone: 434.984.8426 Fax: 434.984.8427 Helpdesk Contract Customers: http://www.myitdepartment.net/gethelp/ ----- Original Message ----- From: [email protected] <[email protected]> To: 'Discussion list for users of sipXecs software' <[email protected]> Sent: Mon Dec 13 03:57:23 2010 Subject: Re: [sipx-users] Remote Workers You have to "mirror" the port on your switch. Or use hub. Sip trace from snom will show sip messages only. I need to see rtp traffic too. Let me describe the problem I encountered some time ago and I suspect it is your problem now. When remote worker calls local phone, sipx relays media through itself. For this sake sipx sends the following sdp offer to local phone: v=0 o=Nokia-SIPUA 63406697693656625 63406697693656625 IN IP4 192.168.12.200 s=- c=IN IP4 192.168.12.200 t=0 0 m=audio 30098 RTP/AVP 96 0 8 97 18 98 13 c=IN IP4 172.23.19.5 a=sendrecv a=ptime:20 a=maxptime:200 a=fmtp:96 mode-change-neighbor=1 a=fmtp:18 annexb=no a=fmtp:98 0-15 a=rtpmap:96 AMR/8000/1 a=rtpmap:0 PCMU/8000/1 a=rtpmap:8 PCMA/8000/1 a=rtpmap:97 iLBC/8000/1 a=rtpmap:18 G729/8000/1 a=rtpmap:98 telephone-event/8000/1 a=rtpmap:13 CN/8000/1 a=x-sipx-ntap:X172.23.19.5-81.211.30.104;38 Note two "c" lines... The first "on the session level" and the second "on the media level". The first "c" line is remote worker address, possibly remotly nated, and not reachable. The second "c" line is ip address of sipx. SDP rfc says that phone MUST use the second one. But alas... Not all phones do that... Some still send rtp to address specified in the first "c" line. That's why I want to see what is happening on the wire, so that one will see where does snom m3 sends rtp.
