A user does a CFwdAll on a 7941 phone to a Sprint cell phone. Internal calls go to the cell phone and ring and can be answered or will eventually go to cell phone voice mail. External calls will ring one time on cell phone and that is it. The caller will hear continuous ringing but will not go to cell VM.
Callee cannot answer call on cell phone even if do so by first ring - in this scenario the caller still just hears ringing even though callee attempted to answer. AT&T / Cingular cell phones work fine. So far it is just the Sprint cell. Any ideas?? We are on Call Manager 4.2; Unity 4.0 Build 4.0(5)
