Re: QChat PTT is doomed Given that these qchat phones are basically CDMA-based, does that mean they default to conventional CDMA voice service if EVDOrevA (qchat) is not available?
If so, then what about this situation: I'm unreachable via qchat, but I'm reachable via conventional voice. Will the network tell callers trying to chirp me to use conventional voice instead?
I'm not even sure how PTT works simply on iDEN by itself, but interested to understand how this hangs together with CDMA-based PTT. |
