I can't get two GV accounts configured on my OBi202. Here's what happens:
In have GV account #1 and GV account #2.
I configure SP1 and Phone Line 1 with GV account #1.... works fine
I then configure SP2 and Phone Line 2 with GV account #2.... always "Backing off"
I deleted both configurations, then reversed the config...
Configured SP1 and Phone Line 1 with GV account #2..... works fine
Configured SP2 and Phone line 2 with GV account #1..... always "Backing off".
I have checked and double checked (including the above reversal test) my GV log-on for each account.
Why can't I get SP2 configured with a valid GV account?
