When migrating from asterisk 1.6 to Asterisk 1.8 my Cisco 7911 Phones hungup the calls in about 32 seconds. Only when calling between Cisco 7911 phones. Calls involving any softphone are 100% OK
In the console I could see:
[Jan 12 11:58:10] WARNING: chan_sip.c:3622 retrans_pkt: Retransmission timeout reached on transmission firstname.lastname@example.org
.13.100 for seqno 102 (Critical Response) – See wiki.asterisk.org/wiki/display/ … nsmissions
Packet timed out after 32000ms with no response
[Jan 12 11:58:10] WARNING: chan_sip.c:3651 retrans_pkt: Hanging up call email@example.com - no reply to our criti
cal packet (see wiki.asterisk.org/wiki/display/ … nsmissions).
I tried several 1.8 releases whith unsuccessfull results. In fact, I had to downgrade to asterisk 1.6 where everything works fine.
I’m not using NAT
Does anybody can help me?
