dial peer.
At this time, more than one dial peer, which is coincided with called party number, is called
hunt group and attempts to make calls according to the priority order based on the consistent
policy.
In other words for the case of VoIP peer, When the call attempt fails due to network connection
fail, gatekeeper reject, another call attempt can be made by other dial peers in the hunt group.
In case of POTS peer, when the attempt is failed due to the port being busy of the voice port,
another call attempt can be made to another dial peer in the hunt group.
The elements for determining the priority order, of the call attempts in the hunt group, are
longest match, explicit preference, sequential, random.
First, longest match is the priority order according to the maximum digit matching with the
destination number of dial peer and outgoing number.
For example, when the outgoing number is 5683848, destination number of dial peer 1 is 568T,
the destination number of dial peer 2 is 568…, and the destination number of dial peer 3 is
56838.. and the destination number of dial peer 4 is 5683848, the priority order basing on
longest match is dial peer 4 --> dial peer 3 --> dial peer 2 --> dial peer 1.
Explicit preference determines the priority order basing on a preference of the dial peer.
For example, when the preference of dial peer 1 is 3, dial peer 2 is 2, dial peer 3 is 1 and dial
peer 4 is 0, the priority order basing on the explicit preference is dial peer 4 --> dial peer 3 -->
dial peer 2 --> dial peer 1.
The random priority order determines the dial peer in the hunt group randomly. When the
random priority order is sequential, the order determines the lowest frequency first, which is
selected previously. Such algorithm of priority order is processed in combination, for instance,
processing the default setting of dial-peer 0 can be determined by longest matching in the first
stage, explicit preference in the second and random in the third.
The first setting related to the hunt group is selection of hunt algorithm.
Step Command Usage
1
model name# configure
terminal
Get into global configuration mode
2
model name(config)# dial-peer
hunt [0-7]
Apply the priority order algorithm from 0 to 7 as to
follow:
0 – (default) longest match, explicit preference,
random
1 - longest match, explicit preference, sequential
2 - explicit preference, longest match, random
3 - explicit preference, longest match, sequential
4 – sequential, longest match, explicit preference
5 - sequential, explicit preference, longest match
