Each search request is assigned a hop count value by the
system that initiates the search. Every time the request is
forwarded to another neighbor gatekeeper or proxy, the hop
count value is decreased by a value of 1. When the hop count
reaches 0, the request will not be forwarded on any further.
For search requests initiated by the local VCS, the hop count
assigned to the request is congurable on a zone-by-zone basis.
The zone’s hop count will apply to all search requests originating
from the local VCS that are sent to that zone.
Search requests received from another zone will already have
a hop count assigned. When the request is subsequently
forwarded on to a neighbor zone, the lower of the two values
(i.e. the original hop count or the hop count congured for that
zone) will be used.
For H.323, the hop count only applies to search requests.
For SIP, the hop count applies to all requests sent to a zone,
affecting the Max-Forwards eld in the request.
The hop count value can be between 1 and 255.
The default is 15.
When dialing by URI or ENUM, the hop count used is that
for the associated DNS or ENUM zone via which the
destination endpoint (or intermediary SIP Proxy or
gatekeeper) was found.

Conguring Hop Counts
!
If your hop counts are set higher than necessary, you may
risk introducing loops into your network. In these
situations a search request will be sent around the
network until the hop count reaches 0, consuming resources
unnecessarily.
