Normal Mode Flow Diagram
In normal mode, user of PSTN side need dial twice. Firstly, dial the FXO number, and
secondly, dial the destination number of IP side. So there is a problem: billing of PSTN-FXO,
FXO-IP is not synchronized, which means even IP side is not reached, PSTN side still has
billing list.
And the call of PSTN-To-IP direction usually has demand on displaying the caller ID of
PSN side. R32 provides caller ID transport transparently function, which can replace the
caller ID by the caller ID of PSTN side, and server need support at the same time.
R32 can also change the Caller ID of PSTN side, such as change 062304138 into
62304138.
