Caller ID on ICS 7750

Caller ID only shows inbound number on inside phone and all outbound calls only show the extension of the dialing station. Attempted prohibiting calling party presentation on MGCP gateway but had no success. Would like to restrict all outbound calls to a Caller ID DN but it does not seem to work either.

Re: Caller ID on ICS 7750

Not quite sure if I follow your question. Are you saying you want all outbound gateway calls to appear to the called party as one specific number? So...all calls outbound from any phone would show as 501-555-1212 on the caller ID of the called party?

You can change the External Phone Number mask per line from within the phone configuration/DN configuration screen.
