Removing digits on incoming called number

Mihkel Laur

Hello! 

 

I am asking advice on what would be the best practice in this scenario: 

 

Inner DN numbers are 7 Digits long

For the numbers to be routable inside the network with other PBXs, they need to be 13 digits. The first 6 are for routing and are always the same. 

 

When dialing out, I am using external mask on the routing pattern. So my number appears as xxxxxx xxxxxxx. 

What would be the best way for discarding the first 6 digits (so that they can be routed in CUCM) when they are calling back? 

 

CUCM version 11.5 

For SBC we have CUBE

 

Thanks in advance

This can be accomplished by creating called party transformation pattern in CUCM.

 

create called party transformation pattern:

pattern: xxxxxx.xxxxxxx

put in a partition

called party transformations:

discard digits: predot

 

and put called party transformation CSS (having above partition) on inbound trunk or gateway.

Two ways.  (1) Use a voice translation rule in the CUBE to truncate the number.  (2) Use a translation pattern in CUCM, setting the trunk CSS so that's all that it sees.

Thank you! 

 

We tried with CUBE but had some issues. This solution worked immediately. 

 

All the best

Great. Good to see proposed solution worked.

Thanks
