VoiceFinder AP1100 VoIP Gateway User’s Guide Version 1.1AddPac Technology Co., Ltd. - 142 -5.3.4. Hunt Group-related Configuration5.3.4.1. Basic Concept and ConfigurationTo select the outbound POTS that is going out of the router or to select the VoIPdial peer, the user shall compare the called party number of the inbound calland the destination pattern of the dial peer. At this time, more than one dialpeers corresponding to the called party number belong to a hunt group, anddial peers of the hunt group attempts a call according to the given priorities.In other words, the VoIP peer attempts a call to a dial peer of the hunt groupwhen the call is failed due to network connection failure, gatekeeper failure, orgatekeeper rejection. And the POTS peer attempts a call to another dial peerof the hunt group when the call is failed due to corresponding voice port’sbeing busy. Factors deciding priorities to attempt calls in the hunt groupinclude the longest match, the explicit preference, the sequential, and therandom.The longest match decides priorities by the maximum digits matched betweenthe origination number and the destination number of the dial peer. Forexample, consider that the origination number is 5683848, the destinationnumber of dial peer 1 is 568T, the destination number of dial peer 2 is 568….,the destination number of dial peer 3 is 56838.., and the destination number ofdial peer 4 is 5683848. Then, priorities of the dial peer by the longest match willbe in order of dial peer 4 → dial peer 3 → dial peer 2 → dial peer 1.In the explicit preference, the order set in the preference of the dial peerdecides priorities. For example, consider that the preference of dial peer 1 is 3,the preference of dial peer 2 is 2, the preference of dial peer 3 is 1, andpreference of dial peer 4 is 0. Then, priorities of the dial peer is in order of dialpeer 4 → dial peer 3 → dial peer 2 → dial peer 1.The random decides the dial peer within the hunt group randomly.
