Hunting Group. For example: Handset 1, 3 and 5 are members of the same Hunting
Group, the rest of the Handsets may have separate numbers and may be reached
independently. Any Handset, member of a Hunting Group that is not registered with a
SIP account, will be able to place outbound calls using the SIP credentials of the
primary Hunting Group Handset.
For example: Handset 1, 2, and 3 are members of the same Hunting Group. Handset 1
is registered with a SIP account. Handset 2, and 3 are not registered. Handset 2 and 3
will be able to place outbound calls using the SIP account of Handset 1. Select
appropriate value for Hunting Group feature. The original SIP account should be set to
