This feature allows user to setup a single SIP account on the gateway and have the ability to use all FXS
ports to make/receive calls. Using this feature, all ports active in same hunt group will have the same
phone number and incoming calls will be distributed in a round robin manner among the ports active in
that hunt group. The number of hunting groups is limited by the number of ports each GXW model has -
i.e. each port can be its own hunt group. The most practical and efficient way to use hunt groups is to
assign 2 or 3 ports to separate hunt 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 4008 ports
configured as a hunt 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 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.
