●
supports substitution of SHIM-based IPSec client addresses for the local IP address
within H.323 signalling messages.
Alternate Gatekeeper - When an agent registers an IP Endpoint with an Avaya
●
communication server, a C-LAN circuit pack IP address is sent by the server to the IP
Endpoint. If registration is successful, the Avaya communication server sends back the
IP addresses of all the C-LAN circuit packs in the network region. These addresses can
be used if call signaling on the original C-LAN circuit pack fails.
Support for server load balancing across gatekeepers - Registration and usage of
●
Avaya communication servers can be distributed across multiple C-LAN circuit packs
within a network region. This increases performance and reliability for all IP Endpoints.
Application updates - This feature can be used to search for updates to Avaya IP Agent.
●
During each start of Avaya IP Agent, the Uniform Resource Locator (URL) address
specified is searched. If an update is found, it is installed. This feature saves time and
effort for administrators because they do not need to visit each installation or create
remote administration scripts through third-party applications.
