Displaying extension caller ID instead of cell phone for internal calls

[Michael Murray]

Is there a way to associate a user's cell phone with their extension such that when the user calls another user in the office, their 4-digit extension will display on the phone instead of their 10-digit cell phone? In other words, I want to make the call look like it's from a phone in the office rather than from an external cell phone.

Are you using MGCP or H.323 ?

Sorry - rookie mistake....

CUCM 7.1(3)

Yes, this is an inherent feature of Mobile Connect.

MobileConnect is configured and the cell phones are set up to be remote destinations. I still see the cell phone caller ID though when calling an extension. Is there a configuration option I'm missing?

Jonathan,

It looks like I can do this with Mobile Voice Access but I would then have to call the MVA access number, enter a PIN, and then make the call:

"Mobile Voice Access extends Mobile Connect capabilities by allowing users to originate a call from a remote destination such as a mobile phone as if dialing from the desktop phone. A remote destination represents a phone that is designated as available for Mobile Connect answer and pickup. The user dials Mobile Voice Access from the remote destination. The system prompts the user for the PIN that is assigned to the user in Cisco Unified Communications Manager. After being authenticated, the user can make a call by using the same dialing methods that would be available if the user originated the call from the enterprise desktop phone."

Is this what you were referring to?

No. This can be achieved without having to dial-in to MVA number.

The system needs to identify the number you are calling from as a RDN number to be able to manipulate it to extension number. By default it will try to match the complete number received from PSTN (ANI) with the RDN set.

Typically, we set the RDN prefixed with a 9 so as to enable Mobility to call successfully out a gateway. Since the RDN contains this 9 and incoming ANI may not have this 9 it will not recognize it as a RDN.

You can change the default mechanism to partial match of say example last 7 or 8 digits.

Go to System > Service Parameter > Select Publisher > CallManager Active Service

Same place where you configured mobility settings there will be a parameter for matching RDN.

Change it to "Partial Match" and no. of digits to partial match as 7.

It will work. (Also you will notice when you call in MVA IVR to make calls, you will just be asked for PIN instead of RDN & PIN as the system has already identified your RDN)
