Users who have Avaya one-X® Communicator in the Telecommuter mode on the personal computers have Other Phone configured as the mobile number. When the user receives an incoming call, the number that the mobile displays is the extension number and not the original caller ID.

To allow the user to see the original caller ID instead of the extension, set the Caller ID for Service Link Call to H.323 1xC field on the Trunk Group screen to original-calling-number. Before sending the call to the service link, Communication Manager changes the calling party number to the original calling party number.

The default value of the Caller ID for Service Link Call to H.323 1xC field is station-extension. Communication Manager does not change the calling party number when the value is station-extension.

Caller ID for Service Link Call to H.323 1xC is the outgoing service link trunk group field.
