I had my Obi 100 setup with google voice on both SP1 and SP2 (one for me, one for wife). This has worked great but with GV going away, I switched. Now using
voip.ms for SP1 did incoming/outgoing and got a callcentric free did for SP2. These are both registered and working.
However, I getting a constant high pitch background noise on my home telephone attached to Obi. I never had this issue before. It's there a soon as I get a dialtone. It's there when receiving a call on SP2. So since it's there with both
voip.ms and callcentric, it's has to be with obi device?
