We have successfully deployed Jabber MRA for a customer. The internal dialplan is a 4 digit plan. AD has the users 4 digit DN in the telephonenumber field which works very well for on premise requirements. Unfortunately when a call is made from the Jabber mobile client when the option to call over the cell network is selected obviously requires the full e164 number for the contact too. What is the recommended way to achieve 4 digit dialling on premise and still allow the contacts to have the option to call using the cell network with the full number ?
