General Delivery Mailboxes for Hunt-Groups in CUE
When the hunt options for a hunt-group are exhausted (i.e., no members answer), to ensure calls are not lost it is often desirable to send calls to voicemail. The question becomes, then, where are calls delivered? In Cisco Unity Connection and Cisco Unity its possible to use Alternate Extensions (for example), but what about CUE? Although it is possible to create a subscriber specifically for voicemail for subscribers, this does limit flexibility of the solution. A better option is to use a General Delivery Mailbox (GDM). One caveat of using a GDM is that MWI notification is not available, not even to group members, however this limitation should be considered in the context of the solution. What you can do to work around this limitation is configure message notification from the GDM to a "real" subscriber - the real subscriber either receives immediate notification, or a voice message indicating that a message is waiting in the GDM (and the subscriber *will* receive MWI on the notification message, if it is delivered to voicemail of course).
Configuration of a General Delivery Mailbox requires:
- Creation of the group that will host the GDM
- Assignment of a phone number to the group (i.e. the hunt pilot)
- Adding necessary members to the group - these members will not receive MWI, howver when a message is received it may be accessed using "Option 9" in the personal mailbox menu, or via the TUI using VoiceView Express
The following configuration defines a new group, Sales, with pilot number 9999. 2 regular Unity Subscribers are added to the group. These Subscribers automatically have the ability to manage voice messages and record prompts; no other permissions are required.
username Terrance create
username Jim create
username Terrance phonenumber "2003"
username Jim phonenumber "2001"
groupname Sales create
groupname Sales phonenumber "9999"
groupname Sales member Terrance
groupname Sales member Jim
Observe the SIP trace on CUE including, importantly, the last-redirect number - the hunt pilot of 9999.

There are 2 methods to change greetings for General Delivery Mailboxes:
- As part of enrollment (either accessing using the telephone via the personal mailbox, or using the VoiceView Express TUI)
- At any time under the context-sensitive General Delivery Mailboxes (under the GDM context, using either of the above 2 methods)
