Setup - 3845 router with sip trunk to A-Z Provider plus 1 x 30 channel PRI.
I have calls working fine over the Sip trunk and have mulitple dial-peers with preferences. However the failover only seems to work if the sip trunk is down. If the call is sent to the provider and it fails the router doesnt failover to the other dial-peer preference ie local isdn.
Is it possible to get failover working on congestion or some other sip response code other than the sip trunk being down?
