TURN server port configuration: if the port of the TURN server is changed while the TURN
server is running, then the TURN server must be restarted before the port change takes effect.
This can be achieved by turning TURN services Off and then On again from the TURN
configuration page.

Out of date call and registration status: call and registration status displays can be out of
date if the status changes mid-call or mid-registration. Some of the call/registration status
information that is displayed is only updated when the call ends.

Seconds since last refresh and Seconds to expiry do not update on the web interface:
the Seconds since last refresh and Seconds to expiry fields on the Registration details
web page do not get updated if a manual refresh of the web page is performed.

SIP DNS zone defaults to UDP: searches made through DNS zones use UDP for A record
lookups. They do this even if UDP is disabled at the SIP protocol level (on the SIP page).
However, if SIP UDP is disabled, the call will not connect.
This scenario is more likely to occur in new installations of X7 software which has SIP UDP
disabled by default.
The workaround is to enable SIP UDP.

VCS allows port overlap for disabled protocols in multi traversal zones:
Symptom: some messages will not traverse the traversal zone.
Conditions: two (or more) traversal zones are configured with identical port numbers for a
disabled protocol (such as SIP).
Workaround: configure unique port numbers for each traversal zone and protocol (H323, SIP),
even if the protocol is disabled.

dialedDigits returned in RRJ does not indicate the actual alias which is a duplicate:
Conditions: a Cisco TelePresence VCS configured as a H323 gatekeeper returns an RRJ
when a H323 endpoint attempts to register with an alias already registered to the gatekeeper.
Returning the RRJ due to duplicateAlias is correct but the dialedDigits value returned is the first
terminalAlias, not the actual duplicate alias.
Workaround: verify on the VCS which aliases are registered to the gatekeeper to determine
where the duplicate alias resides.

Phantom B2BUA calls appearing up in call status: the Call status page (Status > Calls >
Calls) can show phantom calls through the B2BUA. These are typically calls that were never
established. Such calls remain visible on the Call status page until the Cisco VCS is next
restarted.

B2BUA does not support session timers (RFC 4028)
Symptoms: if a call is not properly cleared up with a BYE (either from the Cisco endpoint or the
MOC/Lync client) then it is not cleared from the Cisco VCS. It remains visible under call status
and if the Cisco VCS Expressway is used for TURN services the TURN session will remain.

"sip:" prefix is not stripped before CPL search:
Symptoms: sip: and/or h323: prefixes to URIs are "unexpectedly" part of the pattern match in
CPL regexs. If deny rules are put in which do not explicitly cope with sip: or h323: prefixes
hackers may be able to make calls that would have been expected to have been denied.
Conditions: CPL regex rules in place to deny certain URIs, but do not explicitly include a test
that allows a sip: or h.323: prefix.
Workaround: for example, if the deny rule is to deny calls starting with a 9, instead of using a
regex of:
9(.*)
use:
(.*:)?9(.*)
