PSTN Dial Plan
This section enables you to configure “VoIP with PSTN switching” on your system. You can define a range of dial plans to select which calls are routed over VoIP and which are routed over the PSTN line. Prefix numbers are the essential key to distinguish between VoIP and Regular (PSTN) phone calls. If the actual numbers dialed matches the prefix number defined in this dial plan, the dialed number will be routed to the PSTN to make a regular call. Otherwise, the number will be routed over the VoIP network.
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 that you wish to dial out. Maximum digit number is 15.
Action: Specify a dialling method that you wish to use when making PSTN call(s).
Dial with Prefix: The complete number that you have dialled will be dialled on the PSTN (including prefix)
Note: The actual number of valid digits dialled must match the number in the Number of Digits field.
Dial without Prefix: The number that you have dialled will be dialled on the PSTN after the prefix has been removed from it (excluding prefix).
Note: The actual number of valid digits dialled must match the number in the Number of Digits field
Dial at Timeout: The complete number that you have dialled will be dialled on the PSTN (including prefix) once a certain time has elapsed since the last digit was dialled.
Note: The actual number of valid digits dialled must NOT EXCEED the number in the Number of Digits field.
Dial at Timeout no prefix: The number that you have dialled will be dialled on the PSTN after the prefix has been removed, (excluding the prefix) once a certain time has elapsed since the last digit was dialled.
