Configuring Intelligent Routing
Intelligent routing allows the PBX to select routes according to user-defined route selection policies. That is, the PBX intelligently selects trunk links to transmit voice services to implement load balancing with the minimum expense.

Configuring Re-routing Upon a Failure
When the PBX fails to select a route according to the configured route selection policy, it re-selects a route according to the backup route policy specified by the failure index.
Context
Re-routing is configured in the following scenarios:
- Routing failure
The cause is that the trunk link is faulty.
- Call failure
The possible cause is that the SIP trunk link is faulty or the remote device is faulty. The remote device is faulty when the remote device cannot respond to a call request initiated by the PBX. The PBX determines whether the SIP trunk link is normal according to the heartbeat. After the SIP trunk configuration is complete, run the reset command to activate the trunk link. After the trunk link is activated, the heartbeat is enabled.
As shown in Figure 2-61, the PBX connects to carrier A through the R2 trunk, and the call route is 1; the PBX connects to carrier B through the SIP trunk, the call route is 2, and the inter-office call prefix is 1. Re-routing is configured upon a route selection failure. Normally, outgoing calls on the PBX are made through the R2 trunk. When calls fail to be routed to carrier A over the R2 trunk, calls are routed over the SIP trunk.
Prerequisites
- A trunk group has been configured. For details on how to configure a trunk group, see Configuring Trunk Groups.
- Call routes 1 and 2 have been configured. For details on how to configure a call route, see Configuring a Call Route.

Configuring a Call Route Plan Based on Charge Rates
The PBX searches for routes in ascending order of charge routes until it finds idle circuits. If routes have the same charge rate, the PBX searches for routes in ascending order of trunk group numbers. If no idle circuit is found, the PBX searches for routes for which no charge rate is configured in ascending order of trunk group numbers until it finds idle circuits.

Configuring a Call Route Plan Based on User Rights
The PBX assigns different routes for users with different rights. It preferentially selects a route corresponding to a user with advanced right for outgoing calls from the user. If route selection fails, the PBX selects a route corresponding to a user with lower user right.
Context
- Default right: default
- Common right: normal
- Advanced right: advanced
- Super right: super
To forward outgoing calls based on user rights, configure intelligent routing based on user rights. For example, outgoing calls from users with default right and common right are forwarded over an R2 trunk and a SIP trunk respectively. As shown in Figure 2-65, the PBX connects to the carrier network through the R2 trunk, and the trunk group number is 1; the PBX connects to the carrier network through the SIP trunk, the trunk group number is 2, and the inter-office call prefix is 1.
Prerequisites
- A trunk group has been created and its connection parameters have been configured. For details about the configuration, see Configuring a Trunk Group.
- A call prefix has been configured. For details on how to configure a call prefix, see Configuring a Call Prefix.
- A PBX user has been configured. For details on how to configure a PBX user, see Configuring a PBX User.

Routing Base on Time Segment and Calling Number
This topic describes how to configure routing based on the time segment and calling number.
Context
To meet the requirements of selecting different routes in different time segments and for different calling numbers, you can configure intelligent routing based on the time segment and calling number. For example, you can enable the system to route the outgoing calls made between 08:00:00 to 18:00:00 by intra-office user 6000 through SIP1, route the outgoing calls made in other time segments by intra-office user 6000 through SIP2, and route the outgoing calls made by intra-office user 8000 through SIP2 preferentially. Figure 2-67 shows the network.
Prerequisites
A trunk group has been created and its connection parameters have been configured. For details about the configuration, see Configuring Trunk Groups.
A call prefix has been configured. For details about the configuration, see Configuring a Call Prefix.
