During normal operation, internal calls go across our MPLS network using four digit extensions.
When the MPLS network goes down, and the phones on a site register to the local voice gateway as part of SRST, all calls break out locally onto the PSTN network.
This is causing a problem when people try dialling a four digit extension as the PSTN is unaware of the number.
What I'm trying to do is to automatically prefix the STD number to all outbound four digit calls during SRST, but not to prefix any normal PSTN (full 11 digit) calls. This will hopefully mean a user at a site will continue to be able to dial four digits during SRST and make calls as if nothing had happened.
Anyone have any configuration exmaples on how to do this ? I'm looking at the dialplan-pattern command in IOS 12.4.24T1, but am not getting any joy.
Any pointers ?
