No presence PUBLISH generated by PUA in SIP->H323 interworked call in VCS cluster:
Symptoms: sometimes in-call presence is not published by PUA for H.323 calls.
Conditions: H.323 endpoint must register to a cluster peer and the call must come in
through another peer in the cluster. (If the call arrives on the same peer to which the endpoint
is registered, the in-call presence will be fine.)
Workaround: dual register endpoints as SIP and H.323.

The VCS fails to listen on call signaling ports:
Symptoms: The VCS fails to listen on call signaling ports after a reboot / restart / upgrade.
Conditions: The issue is due to a race condition as ports are assigned during bootup. It
occurs rarely.
Workaround: It could potentially be cleared by a restart.

The CPU load of the VCS increases dramatically in X7 when %localdomains% is used
in pattern matching.
Symptoms: The VCS has a high CPU load, reducing responsiveness.
Conditions: The issue is due to the increase in the number of local domains permitted in X7,
and the way in which the %localdomains% keyword is expanded in pattern matching.
Workaround: Explicitly list domains rather than use %localdomains%.

Possible loss of grace period for call licenses (in cluster configuration):
If a cluster peer loses contact with its cluster, the remaining peers can continue to use the
non-contactable peer’s licenses for a 2-week grace period. But, if another peer within the
cluster is restarted during that period, that restarted peer will not be able to make use of the
non-contactable peer’s licenses for the remainder of the grace period.
This issue is resolved; grace periods are now observed if a peer is restarted.

hold/resume: interworked calls can lose video after a hold/resume if there is a change in the
SIP payload type.
VCS now manages correctly a change in the payload type.
