I have a Obi2182 configured with a Google Voice account. It is on my home internet, which has reliable connectivity and good speeds.
Every single call I receive on that device cuts off after about 30-seconds. The call doesn't end, but the line goes dead and I can't hear anyone on the other line.
If I make the call through google voice app on my cell, I don't have this problem.
Edit: I just called my Google Voice/Obi2182 line from my cell. On the Obi2182, the line goes dead and I can't hear the caller on the other end, but they can still hear me.
Edit 2: After the line goes silent, if I put the caller on hold and then resume the call, it solves the problem and (at least after another minute or so) does not go silent again.
Edit 3: I reset the expert configuration to Obitalk's default settings, and turned off any bluetooth. Still not solved. I have the same problem whether using the handset or the speakerphone.
