Dial-peer match everything except specific pattern

[iMarkJavier]

In my lab deployment, i'm using +e.164 pattern in the ITSP and DNs in CUCM. In the VG, i have the following outbound Dial-peer configured:

dial-peer 110 (to CUCM)

destination-pattern +1408555[0-4]...

dial-peer 210 (to ITSP)

destination-pattern +T

if dial-peer 110 failed, it is trying to send the call back out to PSTN. is it possible to create a pattern that can match everything except my DIDs?

Hi,

Try to create a longer match pattern that matches your DNs and block these
calls to PSTN. Then have a wider pattern to send remaining calls to PSTN.
So you will have two dialpeers on PSTN, one to block your DIDs and the
other one to pass all DIDs.

Hi Mohammed,

Can you please provide a sample configuration?

Thanks, 

Mark
