AVCS configurations
AVCS supports three configurations: H.323-only video solution, SIP-only video solution, and a
combined H.323 and SIP video solution.
H.323-only video solution
The H.323-only solution consists of the following components:
● Communication Manager as gatekeeper
● Polycom CMA as gatekeeper
● Polycom RMX gateway
● Polycom VPB-E video border proxy
● Polycom, Tandberg, and Avaya H.323 endpoints
In this solution, the H.323 devices connect through Communication Manager configured as an
evolution server. The Polycom RMX gateway is registered through either Communication
Manager or the Polycom CMA gatekeeper but not both. The Polycom VBP-E session border
controller connects through both Communication Manager and the Polycom RMX. H.323-only
video solution on page 11 illustrates this configuration.
Polycom RMX registered through Communication Manager means:
● it can host ad hoc video conferences
● it dials out using E.164 alias dialing.
Polycom RMX registered through Polycom CMA means:
● it dials out using IP addresses
● it supports encryption to the devices registered to the Polycom CMA.
This configuration represents what was available for video conferencing in the past.
