PSTN Dial Plan (Router with LINE port only)
This section enables you to configure “VoIP with PSTN switching” on your system. You can define a range
of dial plans to make regular calls from the phone attached to the Router to be switched to the PSTN line.
Emergency Service numbers such as 000 should be dialed via the PSTN to provide location information.
Other location sensitive numbers include 13 and 18 numbers.
The first few digits dialed (the ‘Prefix’) are used to distinguish between calls to be routed via VoIP and
PSTN. If the actual numbers dialed match with the Prefix number defined in the dial plan, the dialed
number will be routed to the PSTN to make a regular call. Otherwise, the number will be routed to the VoIP
networks.
The PSTN Dial plan applies to both Phone Ports.
Reminder! In order to utilize this feature, you must have registered and connected to your SIP Server first.
Prefix: Specify number(s) for switching to a PSTN call.
Number of Digits: Specify the total number of digits to dial out (excluding the Prefix). Maximum is 15.
Action: Specify a dialing method you wish to make PSTN call(s).
