When user calls the PSTN line which was connected with the
FXO port, there are three answer mode for user to configure.
4. Ringing Answer Mode (Default Setting): FXO answer the call
once the ring coming from PSTN line.
5. Connecting Answer Mode:
Case A: "Hot Line Number" was NOT assigned in the FXO
port. FXO answer the call once the ring come from PSTN
line.
Case B: "Hot Line Number" was assigned and the Hot line
number belongs to remote VoIP device.
In this case, FXO port will not answer (off-hook) the PSTN till
the user picks up the call.
(Note: This case can avoid charging for the Local PSTN call
when the remoting VoIP devic still ring.)
Case C: "Hot Line Number" was setting and the Hot line
number was assigned to another FXS port in same Gateway.
FXO port will not answer (off-hook) till the Phone (connected
to the FXS port) was picked up by user.
(Note: This case can avoid the Local PSTN charge when the
FXS port still ring.)
6. Non Answer Mode: FXO will NOT answer the call in any time.
(Note: Some ITSP only let the FXO for termination function,
they do not user use the FXO port for origination)
