Configuring Hunt Groups in SIP IPBGs

Overview

If an application requires that hunting be implemented at the CPE, tiered ring-groups can be used in AOS IPBGs to act as a hunt group.

Only an analog (FXS) user can be configured as a member of a ring-group. SIP users and proxy users cannot be members of a ring-group. Likewise, TDM trunks cannot be a member of a ring-group. Each ring-group can contain only 1 member.

The hunting feature is only applicable for calls inbound from the SIP network. If the member assigned to the first ring-group is busy, or if the configured number of rings occurs before answer, the call will roll to the next ring-group defined by the ‘coverage internal <extension>’ command. Note: The call flow always adheres to the coverage defined in the original, called ring-group.

Configuration

There are 3 steps to implementing hunt groups in AOS IPBGs.

1. Set the system forward-mode to ‘local’. This is a global configuration command:

(config)# voice forward-mode local

2. Configure a dial-plan entry for the ring-group extension(s) and used the default named digit timeout. This is a global configuration command:

(config)# voice dial-plan <#> extensions <extension_pattern> default

3. Define the ring-groups and coverage statements.

When assigning a user to a ring-group, add it as a member and as a logged-in member. Remember that only 1 member can be configured per ring group. This is a ring-group

configuration command:

(config-6351)# member <voice_user_number>

(config-6351)# login-member <voice_user_number>

When coveraging from one ring-group to another, use the syntax ‘coverage internal <extension>’. This is a ring-group configuration command:

(config-6351)# coverage internal <ring_group_number>

(config-6351)# coverage internal <ring_group_number>

Sample Configuration

Below is a complete sample configuration for a hunt group. In this example, calls to 8884238726 (this is the number received in the INVITE) would first ring extension 1001, then 1002, and then 1003:

!

voice forward-mode local

!

voice dial-plan 1 extensions 2000X default

!

voice user 1001

  connect fxs 0/1

!

voice user 1002

  connect fxs 0/2

!

voice user 1003

  connect fxs 0/3

!

voice ring-group 8884238726

  type linear

  num-rings 4

  member 1001

  login-member 1001

  coverage internal 20002

  coverage internal 20003

!

voice ring-group 20002

  type linear

  num-rings 4

  member 1002

  login-member 1002

!

voice ring-group 20003

  type linear

  num-rings 4

  member 1003

  login-member 1003

!
