To configure the hop count for a zone:
VCS Configuration > Zones.

 page.

You will be taken to the

In the 
Configuration
 section, in the

 field, enter the hop count value you wish to use 
for this zone.
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.
