Registration
TO (hrs) Registration Timeout. Sets the number of
hours of inactivity after which the
dynamic registration of a terminal expires.
Only the dynamic (online) properties will
be unregistered. If the endpoint is also
static (predefined), the static properties
remain valid.
IRQ Interval
(sec) The interval, in seconds, between IRQ
messages sent by the Gatekeeper. IRQ mes-
sages are sent to all online endpoints registered
as dynamic in order to verify that the
endpoints are online. The number you set
determines the delay between two IRQ
messages to the same endpoint. Choosing the
desired delay should take into account the
following factors:
• IRQ messages add to the traffic already
present over the network, and the shorter
the delay, the more IRQ messages are sent.
However, the longer the delay, the longer
it takes for the Gatekeeper to detect
dynamic registrations that have ceased to
be online.
• The delay parameter relates to the interval
between two IRQ messages per one
endpoint, so the actual number of the IRQ
messages the Gatekeeper creates during
this interval should be multiplied by the
number of endpoints registered
dynamically.
• To disable the IRQ polling, set this value
to zero.
• The effective IRQ interval cannot fall
below three times the RAS timeout.
• IRQ messages will not be sent at a rate
exceeding 20 per second.
