GateKeeper RAS Parameters

 

RAS TTL 
Value 

The H.323 Gatekeeper “Time 
to Live” value.  As soon as a 
MultiVOIP gateway registers 
with a gatekeeper (allowing 
the gatekeeper to control its 
call traffic) a countdown timer 
begins. The RAS TTL Value is 
the interval of the countdown 
timer.  Before the TTL 
countdown expires, the 
MultiVOIP gateway needs to 
register with the gatekeeper in 
order to maintain the 
connection.  If the MultiVOIP 
does not register before  the 
TTL interval expires, the 
MultiVOIP gateway’s 
registration with the 
gatekeeper will expire and the 
gatekeeper will no longer 
permit call traffic to or from 
that gateway.  Calls in 
progress will continue to 
function even if the gateway 
becomes de-registered. 

Gatekeeper 
Discovery 
Polling 
Interval 

integer 
60 - 300 

The interval between the voip 
gateway’s successive attempts 
to connect to and be governed 
by a higher level gatekeeper.  
The Primary GK is the highest 
level gatekeeper.  Alternate 
GK1 is second; Alternate GK2 
is the lowest order gatekeeper.

Gatekeeper 
List 
(Y/N) 

When selected, voip will seek an alternate 
gatekeeper (when none of the 3 gatekeepers 
shown on this screen are available) from a 
list.  The list will reside on the Primary 
gatekeeper or one of the Alternate 
gatekeepers. The gatekeeper holding the list 
would download that list onto the voip 
gateways within the system.
