the LifeSize Gateway to unregister from its gatekeeper when
no cable connection is found. When at least one cable is
connected to the LifeSize Gateway, the LifeSize Gateway can
register to its gatekeeper. If no cables are connected to the
LifeSize Gateway, the LifeSize Gateway is automatically
unregistered from the gatekeeper (see
for more information).
Select the Send load balancing messages (RAI) check box to
12
enable the sending of RAI messages to the gatekeeper for the
purpose of load balancing on the network. If you select this
option, perform step 13
Gatekeepers can perform load balancing on the network using
feedback from the LifeSize Gateway in the form of Resource
Available Indication (RAI) messages that inform the gatekeeper
of LifeSize Gateway resource availability. If the LifeSize
Gateway is unavailable, the gatekeeper performs line hunting
operations to route the call to an alternative gateway.
When you set the LifeSize Gateway for RAI/RAC, it sends
periodic RAI messages that inform the gatekeeper of the current
resource availability in the LifeSize Gateway. The gatekeeper
responds with Resource Available Confirmation (RAC)
messages to acknowledge receipt of the RAI messages. In
13 and step 14, you can configure the upper and lower threshold
for triggering RAI messages according to resource availability
in the LifeSize Gateway.
13 In the Send 'busy' when load is more than field, enter the
upper threshold for LifeSize Gateway resource utilization as a
percentage of total resources. When resource use is greater
than the threshold, the LifeSize Gateway sends the gatekeeper
a 'busy' RAI message, indicating to the gatekeeper that it
should stop routing calls to this LifeSize Gateway.
14 In the Send 'free' when load is more than field, enter the
lower threshold for LifeSize Gateway resource utilization as a
percentage of total resources. When resource use is less than
the threshold, the LifeSize Gateway sends the gatekeeper a
'free' RAI message, indicating to the gatekeeper that it can
resume routing calls to this LifeSize Gateway.
