Hi I'm having an issue with just one of the phones (snom300) attached to our asterisk server (1.4.17 using RealTime) Sometimes (not consistently), any outbound call cust off at 20 seconds exactly and I see the following in my asterisk console [Aug 6 10:37:24] WARNING[1679]: chan_sip.c:1946 retrans_pkt: Maximum retries exceeded on transmission 3c3251e0edaf-4jnjbmy9uupi for seqno 2 (Critical Response) [Aug 6 10:37:24] WARNING[1679]: chan_sip.c:1970 retrans_pkt: Hanging up call 3c3251e0edaf-4jnjbmy9uupi - no reply to our critical packet.
There as another SIP phone plugged into the same router and that has no issues at all and inbound calls are not affected either. The codecs order on the phone match up to those set on the server (g729;alaw;ulaw;;). There are about 50 other phones attached to the server and none of the others have this issue. Well actually, one did but that person got a new handset (they were previously using a very old and rubbish Grandstream) and the problem immediately stopped. Has anyone experienced anything like this before? -- Ishfaq Malik Software Developer PackNet Ltd Office: 0161 660 3062 _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- AstriCon 2009 - October 13 - 15 Phoenix, Arizona Register Now: http://www.astricon.net asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
