Hunting Group
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 SIP 60X gateway 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 SIP 608 ports configured as a hunt group. The SIP 608 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 SIP 608 will allow 8 concurrent calls to the same
SIP number. All office members can be reached remotely using the same phone number
