Hi guys, I have a problem with my GrandStream Budge Tone 100. It's REGISTERed with my SER, I can make and receive calls with it but all the calls are voice echoed. Them same doesn't happen at the other softphone or hardphone I'm talking to. I mean, softphone calls to BT100, only BT100 remains with echo, the sofphone has excellent voice quality as bt100 but with no echo . Did anybody have the same problem ??
