Hi
Using OBi212, I'm forwarding incoming PSTN to Google voice. During the call, the volume (Gain) keeps increasing till I hear a sharp beep (Whistle) for few seconds then it stops and the volume back to it's normal level.
My setup:
OBi212
Hardware Version: 1.4
Software Version: 3.2.2 (Build: 5921EX)
Line ChannelTxGain: -1
Line ChannelRxGain: -2

Any help is highly appreciated
Thank you
