Dial tone ok, no static, call is fine.....at first.
After some time on the call usually 7-15 min, the line has a very loud bussing sound that won't stop.
The call has to be disconnected and call back the same number to hear the other party.
Using a Panasonic cordless phone and obi 202 with google voice.
If one of those factors is causing the issue, why only after a certain amount of time?
