Is there an option to change the caller ID based on outgoing trunk + outgoing extension ?
I have 2 E1 the callerID from the extension will only work for the E1 Line it was set up for .
Ideally I would like to have postfix callerID set up on the extension level CallerID and then add it to a prefix callerID from the turnk .
E.g.
Extension 425 will have a callerID in the field with value of 425 (or any other 3 digits)
Outgoing E1 line 1 will have 0872713
Outgoing E1 line 2 will have 0872234
when 425 will use Line 1
Caller ID will be 0872713425
when 425 will use Line 2
caller ID will be 0872234425
Thanks for any help .
