Missed Call Log - Selective Digit Strip

[whoiuser]

All,

I have the following configuration

PSTN > Asterisk > SIP Trunk > CM 11.5

I have successfully inserted the required 91 before the 10 digit number. Currently, the Asterisk is acting as the PSTN and is sending all 10 digits from network callers. However, I have Asterisk users as well whose 4 digit ext number is now prepended with a 91.

Is there an easier way to strip those prepended digits from ONLY the 4 digit extensions?

Thanks kindly for any thoughts or suggestions

Do you have a gateway or is Asterisk integrated directly with CM ?

[whoiuser]

No gateway, Asterisk is connected to a SIP trunk, the other end terminating in CM and running on all nodes.

I guess the real question should have been whether I can selectively apply the 91 to certain call types. It looks like it should not be to hard and I would prefer not to have Part / CSS software just to accomplish this.

I am looking as well so if I arrive at an elegant and clean solution, I will post it here.

Thanks for your time
