About Hop Counts
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, it will not be forwarded on any further.
The hop count used in search requests initiated by the local
VCS is configurable on a zone-by-zone basis. This value will
apply to search requests originating from the local VCS and
sent to that zone. It will also override any existing hop counts in
requests being forwarded to that zone if the original hop count
is higher (if the hop count is lower than that set for the zone,
the lower value will apply).
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 field in the request.
The hop count value can be between 1 and 255.
The default is 15.
Call Processing
When dialing by URI or ENUM, the hop count used is
that for the associated DNS or ENUM zone via which the
destination endpoint was found.
