If Yes, the phone connected to the FXS port will ring a configured amount of
times (see above). If not, the phone connected to the FXS port will not
ring.
If the PSTN Ring Thru Delay is set to Yes, all incoming PSTN calls through
FXO will ring the phone connected to the FXS port, after this delay or after
caller id is detected (whichever comes first).
Range is 2-10 seconds. Default is 6 seconds. Option is used to detect PSTN
hang up when FXO port is not answered.
Used to customize timeout value between PSTN outgoing calls. Range is 0-
10 seconds. Default is 4 seconds.
Digit length and Dial Pause are port digit dialing configurations; FXO needs
to dial out digits for VOIP to PSTN 1 stage calls, and unconditional call
forward to PSTN, and route to PSTN. Digit Length is the play time for each
digit.
Note: In order to receive the caller ID information, the delay should be set to
a value larger than the delay required to complete the PSTN caller ID
delivery.
Dial pause is the time between 2 digits for the same scenario as explained
above.
Used for PSTN to VoIP calls. PSTN users need to enter the FIRST digit
within the first digit timeout period. Otherwise the call will be dropped.
When dialing from the PSTN to VoIP, subsequent digits have to be input
within the period of inter-digit timeout. Otherwise the dial plan thinks it is the
end of the digit input.
Wait for Dial tone is used for one stage VoIP to PSTN calls. If set to Yes,
the device will first obtain a PSTN line and a dial tone from a central office.
After obtaining the dial tone, the digits dialed will be sent to the central
office.
This configuration is applicable for VoIP to PSTN calls and indicates one or
two stage dialing methods.
