[Asterisk-Users] SIP/2.0 487 Request Terminated problem on Cisco 7960

[Chris Stenton]

With todays CVS head I am getting the following  being sent after a call has 
been terminated
on my Cisco 7960. It eventually gives up with a critical error.

chan_sip.c:1132 retrans_pkt: Maximum retries exceeded on transmission 
000b46a0-8661000a-4405e325-7e25031f at 192.168.123.20 for seqno 102 (Critical 
Response)

Any ideas I am sure it was working ok with cvs head a month ago.
