This feature allows the 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 4024 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 24
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 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.
