Branch IP phones work in a SRST mode during WAN or CUCM failure.
IP phones register on a router with extensions. 2....
These extensions correspond to PSTN number range 67032...
The problem: incoming calls from PSTN don't work, outgoing calls to PSTN work fine.
Could anyone point what wrong or missed in the configuration shown below?
I see your error... basically you are trying to apply trans rule 2 to incoming calls, but have applied it under call-man-fallback mode.
This means it applies to calls to/from ephones - the outbound leg in this case.
As the call coming in hasn't been sent to any ephone yet, it doesn't hit the translation.
You need to translate it either on the inbound peer (dp 1) or use the dialplan-pattern command under call-manager-fallback.
dialplan-pattern 1 67032... extension-length 4 extension-pattern 2...
