Avaya 7 manual Configuring Alternate Gatekeeper on Avaya communication servers

Chapter 4: Avaya IP Agent enhanced configuration options

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:

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.
