Ring Groups - Personal

Overview

Personal Ring Groups (PRG) are an association of two or more devices for a single user under a common Directory Number (DN). The devices ring simultaneously (Ring All) when called. The typical scenario is a person's desktop phone and cell phone twinned together, where the desk phone is considered the prime extension, which is referred to as the pilot number or prime member. Other group members are referred to as non-prime members.

PRGs provide functionality that is similar to Ring Groups and Hunt Groups, but for a single user. In contrast to Ring Groups, PRGs support Ring All, but not Cascade Ringing and support a maximum of 8 as opposed to 32 members. See Ring Group below for feature interaction information. In contrast to PRGs, Hunt Groups can include Trunks. See Hunt Group below for feature interaction information.

PRG programming includes a One Busy/All Busy option that can be turned on or off as required.

The new Handoff feature for PRGs allows a call to be pushed or pulled from one group member to another. See Handoff for more information.

Resiliency

A PRG is resilient if its prime member is resilient. The group's primary and secondary ICPs match that of the prime member. A PRG displays in the Personal Ring Groups form on the 3300 ICP controller where the group is hosted. The PRG displays on the secondary controller if the group is resilient. Members can be added from either the group's primary or secondary controllers.

If a device is resilient it can be programmed as a PRG member on either its primary or secondary ICP as long as the group is resilient and its primary and backup ICP are the same as that of the device. If the device is non-resilient it can only be programmed on its hosting ICP.

See the 3300 ICP Resiliency Guidelines for more information.

Conditions and Feature Interactions

This section lists conditions and exceptional feature interactions of PRGs.

CAUTION: The following forms allow you to delete a device associated with the prime member of a PRG. Deleting the device will remove all members of the group and the group itself.
- Multiline IP Sets
- User and Device Configuration
- Wireless IP Sets

The following forms allow you to delete a device associated with the non-prime member of a PRG. Deleting the device will remove the member from the group.
- Multiline IP Sets
- Wireless IP Sets
- Single Line IP Sets
- Multiline DNI Sets
- Single Line DNI Sets
- User and Device Configuration

General

This section lists general conditions of the feature.

CAUTION: For Remote Directory Numbers, changing the cluster element index programming for a DN that is a member of a PRG could cause problems with database integrity. As a guideline, DNs which are members of a PRG should not be changed from the Remote Directory Numbers form.

Feature Interactions

CAUTION: Exercise caution if you are using Auto Answer with PRGs. If Auto Answer is enabled on one of the ringing members, the call is automatically answered by that device, and if the user of the auto-answered device is away, the caller may be left unattended on speakerphone.

Programming

  1. Multiline IP Sets form
    If necessary, define a DN to be used as the Prime Member of the Group. For the interconnect number, enter an integer between 1 and 64, that references an entry in Interconnect Restriction.

  2. Personal Ring Groups form
    Assign the Prime Member of the PRG by clicking Add and specifying a DN for a multiline IP set or Hot Desk user.

  3. Personal Ring Groups form
    Add members to the group by clicking Add Member and specifying the DN of each member. Change the Presence setting accordingly. The default is Present.

  4. Personal Ring Groups form (Optional)
    Modify the Number, except in the case of the prime member, and Presence fields using the Change Member operation.

  5. Personal Ring Groups form (Optional)
    Delete a member, excluding the prime member, from the PRG using the Delete Member operation.

  6. Personal Ring Groups form (Optional)
    Delete an entire PRG using the Delete operation at the top of the form.

Feature Availability
