I am new to this thing, and I have GV set up on SP1 and callcentric on SP2. I remember being asked if I wanted to use SP1 as the primary line when I set the thing up, but now I want to change the primary line to SP2, or the call centric line. Is there a way to do this? I have read some posts and tried it but the software seems to have changed since 2011 and I can't change the settings. I have the OBi110.
