I wonder if anybody else is seeing this problem.
Whenever I dial something that results in provider's error message following 3 ascending tones- such as "This number has been disconnected", "All circuits are busy", and such - after that I'm unable to dial any other numbers until I reboot OBI device. Dialing every legitimate phone number now results in "the number you dialed has not received a response from service provider". The problem is fixed by rebooting OBI device.
It's OBI200 , version 3.2.2, working with Google Voice, and as long as I don't dial something that results in the error, it works without a problem ever.
Wondering if others see the same. It has been this way for a while.
