About Hunt Groups in the UC500 and Cisco CME 7.x

With The introduction of Cisco Unified Communications Manager Express 7.0 (CME) on Cisco ISR Routers and the UC520, there are now two different ways to provide hunt groups.

The traditional method is using the ephone-hunt command in global configuration mode.  Using the ephone hunt command requires that all of the endpoints are SCCP ephones.  So if you want to use an analog phone in an ephone hunt, they must be under SCCP control either through an ATA or at FXS port that is under SCCP control using STCAPP.  One of the advantages of this method is that you can define dynamic members of a hunt group that can log in and out to service calls.  Available methods of call routing include longest-idle, peer and sequential.  This also is the default method that CCA1.8 uses for the UC520.

The newer method is to use the voice hunt-group command.

This command has been recently expanded to allow the following:

• Call Forwarding to a Parallel Voice Hunt-Group (Blast Hunt Group).

• Call Transfer to a Voice Hunt-Group.

• Member of Voice Hunt-Group can be a SCCP phone, FXS analog phone, DS0-group, PRI-group, SIP phone, or SIP trunk.

Voice-hunt groups do not support dynamic logins of agents.  To configure these on the UC520 it must be done at the commandline.
