External no as CLI for forwarding calls from cucm

Hi All,


We have CUCM 7.5, MGCP gateway deployed i am facing below issue request you guys to guide me to get solution for this.


  • •1. We have route patters with calling party transformation as below

Prefix: 0110112


  • •2. When we call from extension 1230 using the route pattern xxxx, the CLI display on the called party number is 01101121230

This is correct.

  • •3. When we do call forward all and a call made from an internal extension to this extension CLI display as expected (0110112XXXX, here xxxx is an extension).
  • •4. But when we make an external call to this extension while CallFWDALL is on , the call will be forwarded to the forwarded number. and the CLID display as prefix followed by the original party mobile number, which will be an invalid number. Here what we expect is to display original calling party number.


I have tried all possible way which i know to avoid to prefixing the DID range when call is originated from external number.


If I having H323 gateway I could have strip the digit from dial peer.


Request your expertise to resolve this.

What is your extension range? There are ways, in your case, probably best to use calling transformation patterns on the MGCP gateway. If you send through your extension range, I'll write some trans patterns for you to look over.

As often discussed, had you searched before asking.

You cannot "show" any number except the ones that have been allocated to you by telco.

Otherwise you would be able to spoof caller-ID.

You can configure your gateway to use last number redirect instead of first number redirect..The issue here is that yoru gateway is usign the mobile as the redirect number. Under your gateway settings, I think its on outbound calls, you can select which number is used for call redirect (first or last)

This is what you need....under the gateway endpoints..

Call Routing Information - Outbound Calls

Calling Party Selection: Change from originator to last number redirect


NB: you need to do a shut/no shut on your mgcp gateway for this to work

I'm afraid you did not understood what I said:


You cannot have the original calling number to be show for Call-forwarded calls, no matter what you try or configure.

Hi All,


I got a work around for this and it works in our setup.


1. Assign external phone number mask to each IP phone DN configuration.

2. Do not configure any transformation mask on route pattern other than selecting Calling Party Number Type as Call manager.

3. Select Calling Party Selection as Originator from Call Riouting Information- Out bound calls from Gateway configuration in call manager.


Now my set up is working as below


1. every call from extension showing full qualified PSTN number

2. internal call forwarded from extension to external number showing full qualified PSTN number.

3. External call forwaded from extension to external number showing original calling number.

Then that is the only country, beside USA, that it allows placing calls without enforcing calling number checks.
