model has - i.e. each port can be its own Hunting Group. The most practical and efficient way to use
Hunting Groups is to assign 2 or 3 ports to separate Hunting Groups.
One additional and popular way to use the Hunting Group feature is called “multiplexed analog lines”. In
this configuration, a legacy PBX system with 8 FXO trunks can be connected to 8 GXW 42xxports
configured as a Hunting Group. The GXW can be registered to a SIP server provider using only one
phone number. If the SIP service provider allows multiple calls to the same number, the GXW will allow 8
concurrent calls to the same SIP number. All office members can be reached remotely using the same
phone number in a round-robin fashion.
Example Configuration of a typical Hunting Group:
1. Configure the SIP account from your VoIP Service Provider on FXS port 1 under FXS Ports
webpage.
2. Select Active under the Hunting Group drop box for FXS port 1.
3. For the remaining ports (say 2, 3 and 4) select 1 for Hunting Group.Ports 2, 3 and 4 are now
active members of the hunting group associated with port 1.
This configuration will route all calls directed to FXS port 1 to ports 2, 3 and/or 4 in round robin fashion
respectively if port 1 is busy or times out. You can configure the ring timeout on the Profile page.

FXS Port #1: SIP UserID and Authenticate ID entered, Hunting Group set to "Active"
