Here's my setup:
CCM 3.3 at central location
T1's to remotes
2621's at remote sites with 2 FXO ports
SRST works as far as phones failing over, registering with 2621, and being able to dial 9 and get dial-tone from one of the FXO lines. Is it possible for CallManager to route calls to this site through PSTN when the WAN link fails? Central Site has 2 PRI circuits on a 6009 for outbound/inbound calls.
