Avoid that calls to internal numbers go through gateway

Hi

How do i enable it so that if an internal user at DN 1234, want to call 2345, but are entering the full 0 + 8 digit dial string, does not go through the GW.

( we are using 4 digit for internal calls, 8 for external + 0 )

Some of the internal users are entering the full dial string, as if they where to call local extension.

I want the Translation Pattern ( i think ), to be set up so that if an internal caller, want to dial another internal user, and he is entering 0 + 8 digit, then my CUCM should strip some digits of, and see that this is meant to be an call from internal to internal users.

I know that this should be possible. We are using 4 CSS. Int, Norm, Foreign and All.

Any advice here.

You are correct that you need to use translation patterns.

Create a new translation pattern in the same partition as your phone directory numbers.

For each DID range that you have enter the full number that a user would dial to reach the phones including the 8 access code and XXXX for the last four digits.

Assign a Calling Search space that allows the translation pattern access to the partition containing the phone directory numbers.

Enter XXXX as the Called Party Transformation Mask

The image below shows a translation pattern configured on CUCM 7 configured as described above - CCM4 should be similar.

Hi

Thanks, that seems to be working quite well. Have not run a full test, but tested with my Communicator, but it looks OK.

DNA shows this, and i am reading that to be OK. OR?
