I have a google voice trunk number 774-xxx-xxxx and a main number 203-xxx-xxxx and I would like outgoing calls made from the google voice number to show callerid 203-xxx-xxxx instead of 774-xxx-xxxx. I tried making the change to the caller id field in the trunk setting and/or in the extension settings, but no combination has any effect. I always see the 774-xxx-xxxx number when I call myself using the google voice number. Anyone hav any suggestions for me? Thanks in advance.
