Accessing Hunt Group Voicemail Using a Short Code
To access messages for a Hunt Group, a short code can be created:
For example, for a group called Main:
Short Code: *99
Telephone Number:"?Main" (include quote marks)
Line Group ID: 0
Feature: VoicemailCollect
For system running in Intuity mode, the above will only work if the user is a member of the group and a custom call flow has also been setup for that hunt groups collect start point.
Members of the Main hunt group can now dial *99 from their own extensions to access hunt group messages.
In IP Office mode, to use this short code for access from an extension that is not a member of the hunt group, a Voicemail Code should be configured for the group.
