All of my IP phones are getting kicked off the VPN every few minutes. The model is IP HardPhones Model 4610SWIP. This is a Avaya phone system, but its over a Cisco 5520 firewall. They were working well for about a week, and now its intermitted.
Normally when an IPsec connection terminates ASA provides a reason "peer terminate : ...." in a form of a syslog message.
That would be the fist thing to check.
Also - what has changed a week ago.
