I have an Obi202 setup with a Google Voice number as SP1 and a Callcentric number as SP4. The Callcentric number is listed as a forwarding number in the GV setup so I can use it's CNAM Caller ID lookup whenever a call comes in. It works great.
My question is that since both lines are ringing on an incoming call, when I pick up the phone, which line am I connecting to? Am I connecting directly to the GV number, or indirectly through the Callcentric number?
This matters because I'm thinking of switching to
voip.ms to replace the Callcentric number, but setup the same way.
Voip.ms charges for each incoming call minute.
How do I know which line I connected to when I pick up the phone>
