Configuring a Call Route
A call route defines routing rules for outgoing calls, and is bound to a call prefix and a trunk group. After a call route is configured, the PBX can correctly route outgoing calls.
Context
A trunk group supports a maximum of 48 routes, and the system supports a maximum of 1024 routes.
When a user calls an inter-office user, the PBX extracts the inter-office call prefix from the number, finds a trunk group bound to the call prefix, and then finds the called party.
According to the example in Figure 2-32, the process of an outgoing call is as follows:
- Intra-office user 7001 calls inter-office user 8001.
- After the PBX receives the number, it finds the prefix in the DN set bound to the calling number.
- The PBX finds a trunk group bound to the call route according to inter-office call prefix 8.
- The PBX selects an inter-office line to PBX B according to trunk group 2.
Prerequisites
- The operations of Configuring a Call Prefix have been performed.
- The operations of Configuring Trunk Groups have been performed.

- Configure the custom routing selection policy. For details, see Configuring Intelligent Routing.
Example
Bind inter-office call prefix 8 and trunk group pra01 to the call route route01. When an intra-office user dials the inter-office number starting from 8, the outgoing call is made over the trunk group pra01.
