Quote(I did not see this as "PHONE & LINE Status", but as "PHONE Status"
The headings are slightly different in the OBiTALK Expert pages compared to the web page version. Anyhow, both show the same info.
Item 2 shows the number coming into the OBi from GV as eleven digits starting with "1".
Item 3 shows the number leaving the OBi going towards your phone as ten digits without the "1".
The OBi is following its rules - stripping off the "1" and passing the remaining ten digits to your phone.
Any chance you could try a different phone? I wonder what happens if you put the InboundCallRoute back to default ph, then monitor how the phone behaves with all eleven digits heading its way for a few calls.
