I have an Obi202 with two Google Voice numbers on SP1 and SP2. The Localphone account is on SP3. SP4 is not configured.
Starting yesterday, 3/6/16, I kept getting this error message when I made outbound calls on SP2. It did not happen on every outbound call. But the frequency is high.
Where in the Obitalk settings I need to make change to avoid this annoying error message?
