Calling Number Discrimination
Calling number discrimination is a type of number change. This service allows the PBX to change outgoing called and calling numbers and to limit the call-out right of a calling party using a prefix.
Context
Calling number discrimination can be used in the following scenarios:
- To show a specific number to the called party, configure the specific number to replace the calling number.
- To change the number as a specific number, configure a new number to replace the called number.
- To control the call-out right for calling numbers over a trunk, configure the call-out right.
Prerequisites
- A PBX user has been configured. For details about the configuration, see Configuring a PBX User.
- A call prefix has been configured. For details about the configuration, see Configuring a Call Prefix.
- The PSTN assigns number 28987000 to the PBX user.
