Cisco 7940 phones become unreachable over VPN after a time
...erisk is saving
enough state to come back up in a non-working state or that there is a
VPN issue. I've included a packet trace of 3057 while it is in a
non-working state (below). The trace was done from the ASA.
The Asterisk server is behind a Cisco ASA 5520 and the remote sites have
Cisco 837s. I see a long list of SIP related issues resolved by
http://www.cisco.com/en/US/docs/security/asa/asa80/release/notes/arn804n.html
(which I applied), however this still doesn't seem to have solved the
problem. Is a "Asterisk <=> Cisco-VPN <=> 7940" setup known to work?...
