Resource usage
This section provides statistics about the current and cumulative license usage for calls and registrations.
It shows current and peak (highest concurrent) usage broken down by:
■
Rich media sessions
■
Registrations (including Unified CM remote sessions)
■
TURN relays (Expressway-E only)
It also displays resource and license usage information:
■
Monitored resource usage, expressed as a percentage of the system capacity.
■
Current and peak license usage, expressed as a percentage of the available licenses for each license type.
Each rich media session license allows either 1 video call or 2 audio-only SIP traversal calls. Hence, a 100 rich
media session license would allow, for example, 90 video and 20 SIP audio-only simultaneous calls. Any other
audio-only call (non-traversal, H.323 or interworked) will consume a rich media session license.
