How to change caller ID on mobile phones from specific extension

[rahul14]

Hi All,

Is there a way to change which caller id mobile users would see when a specific extension makes pstn calls?

And what is your call control server, any more details will get you a lot more help than this,

Call control server CUCM 9. I want to change the Calling Party number that gets displayed to external users from specific extensions at a branch. Calls currently utilize the FXO lines for extenal calls so those POTS numbers are shown, however I want SOME extensions at the branch to mask to another calling number when they make an external call. Is this possible without going through service provider?

If you only have FXOs you have no control, they're assigned an ANI by your provider, and you cannot change that, you would need a PRI or a SIP trunk

Ok noted and thanks Jaime. Is there a way however to route outbound pstn calls from specific extensions over SIP/T1 at HQ or would the calls from all the extensions be routed over SIP/T1 trunks if the change is made.

[Jaime Valencia]

What you ask is possible, simply adjust your dial plan, CSS and partitions to make those phones go out through the SIP/T1 trunk.

Ok noted. By dial plan I assume you are referring to the corlist stuff.

Are you able to provide a little code snippet example of how to configure this identifying one extension using fxo while another extension routed over WAN using SIP/T1. Your assistance would be appreciated.

Hello Jaime,

Please see below code attempted. Are you able to identify what is missing or incorrect?
