For FXO ports Gateway must detect disconnect tone to determine
when to disconnect the call, so user must set disconnect tone of
PBX or PSTN network connected to FXO ports.
When making a call from FXO ports, there are 2 ways to detect
callee has already picked up the call, one is to detect reverse
signal, the other is to detect the termination of ring back tone, so
user must set ring back tone of PBX or PSTN network.
(If user doesn’t know about the frequency of disconnect tone or
ring back tone, please refer to
[record]
command to detect
frequency.)
