We have an Avaya IPOffice R9 System that is connected to a SIP Provider for outbound calls. When some users call come customers the number is Identified at JPMorgan and not the Username that we have setup in the Avaya system.
If that same user calls my Home Phone I see the name that we have assigned the user not he Avaya SIP tab. So I know its going though our SIP Provider just fine.
Is there some Caller ID Database that could be used for number lookup that would override the Caller ID Name that is sent along with the call?
