Configuring Number Change
This section describes how to configure calling/called number change, long and short codes, and number mapping.
- 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. - Configuring Long and Short Codes
A short code is used by intra-office users, and a long code is used to display numbers of outgoing calls or used by inter-office users. - Configuring Number Mapping
Number mapping allows the PBX to map external numbers to internal numbers and re-parse numbers and locate called parties according to the matched prefix. - Configuring a Pre-routing Number Change Plan
Before route selection, complete calling or called number change. - Configuring a Post-routing Number Change Plan
After route selection, complete calling or called number change. - Configuring GNR Number Negotiation
The device functioning as the trunk gateway, following the GNR negotiation rules, can meet the hunt group service requirements in the scenario of tandem calls to the iMSS through trunks.
