I have GV on one line, and SIP provider on another. My goal is to allow caller to dial SIP (it has local number in a foreign country), and OBi would dial my office or cell number. Both incoming and out going calls work fine on both lines.
If I bridge to echo test pp(222222222), works fine as well.
However,when I bridge to GV - sp1(1xxxxxxxxx), there is no audio either way.
Any advise would be very welcome. My router is OpenWRT-based, and I didn't make any modifications that I can think of...
