the FXS port) before a PSTN incoming call is bridged to VoIP
Note: The number of rings feature serves as a PSTN answer delay, and should be set
to a larger value to allow enough time for the HT503 to decode the Caller ID signal set
by the central office.
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
hangup when FXO port is not answered.
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.
