Ron and Dave, I'm still lost on this, I can report the following:
I can make an outgoing call from within Gmail account associated with the problem.
I'm signed out of the chat account (I never signed in anyways).
Google Chat is enabled (always has been).
Incoming call from this account is NOT hitting the OBI, its not showing there.
When Username and PW pairs swapped problem moves to SP2 (as Ron suspected, problem pointing to GV account).
However, settings on both accounts are identical (except the username, even the PW are the same), I checked and checked, the only exception is the problem account has a long (about 230) contacts list.
Any suggestion is greatly appreciated, I don't want to lose the GV number since its given to many.
Thanks........Ked
