    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 6351 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 6351

      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

    !
