Chapter 4: Avaya IP Agent enhanced configuration options
40 Avaya IP Agent Installation and User Guide for Citrix June 2007
Configuring Alternate Gatekeeper on Avaya
communication servers
Use the Alternate Gatekeeper feature when an IP Endpoint registers with an Avaya
communication server. When Avaya IP Agent registers with an Avaya communication server, a
C-LAN circuit pack IP address is sent to the IP Endpoint. If registration is successful, the Avaya
communication server sends back the IP addresses of all C-LAN circuit packs defined in the
same network region. Avaya IP Agent can use these addresses as alternatives if call signaling
on the original C-LAN circuit pack fails.
Tip:
Tip: You can better control the usage and workload of C-LAN circuit packs by creating
network regions.
Alternate Gatekeeper configuration
For information on defining Alternate Gatekeeper addresses, refer to your Avaya
communication server documentation.
Configuring server load balancing across gatekeepers
Load balancing for an Avaya communication server refers to the ability of distributing IP
Endpoint traffic across all C-LAN circuit packs that are defined within the same network region.
Load Balancing configuration
Load balancing is achieved by defining all of the IP addresses of the C-LAN circuit packs to be
part of a network region on an Avaya communication server. After this has been completed, IP
Endpoints registering with the Avaya communication server will be automatically assigned to
the different C-LAN circuit packs in sequential order. This helps distribute IP Endpoints evenly
amongst the C-LAN circuit packs.
