You can also use zones to set priorities that determine the order in which TCAs are chosen to record a
call from a particular endpoint. For example, if you have three TCAs in zones A, B and C, and an
endpoint in ‘Zone A’. If the endpoint makes a call that needs to be recorded, you can tell the VCS to
prefer the TCA in Zone A, but if it is not available, to try the TCA in Zone B then Zone C.
You define these zone priority instructions in the zone definition screen of the VCS Administration
Application. The VCS sends the call to the zone that responds first, so if you want to ensure that a VCS
sends calls to the physically closest TCA you need to set the zone priorities so it queries the closest one
first. Also be aware that the VCS uses zones to control and optimize bandwidth, so you need to consider
that if you change the zone priorities.
See section
9 Deployment scenarios
for some examples of how to use zones.
6.4 Turning off recording
There may be circumstances in which you need to turn off recording. For example, the TCA is designed
to tear down any call if recording stops at any point during the call, so if you’re experiencing network
issues that cause the TCA to drop out periodically, you may need to disable it temporarily so you can
continue to use the video conferencing network while the problem is fixed.
To turn a TCA off you need to turn off the policy file on the VCS to which the TCA is neighbored. To
do this, make a backup of the policy file that contains the control instructions for TCA, then replace the
file with the original policy file that doesn’t contain the TCA instructions. This will prevent any calls
being routed to the TCA.
6.5 Preventing users avoiding recording
In a network where endpoint configurations are not locked down, users may be able to change their
endpoint URI. This presents a risk that users can make calls that are not recorded. If recording is
compulsory, ensure that the network is locked down.
