We are having a issue with our Cisco 2811 VoIP routers (C2800NM-SPSERVICESK9-M), Version 12.3(8)T8). SRST works fine when we initiate a fall back by brining the circuit down. However, if we initiate a power failure or reload the router it will use the dial-peers intended for fall back instead of MGCP. The router registers properly with CCM v 4.1(3)SP1. So when you call it rings once then goes to fast busy.

What would cause the router to use the fall back dial peers instead of the MGCP dial peers? Thanks!
