EX60/90 endpoints registered to CUCM in SIP mode do not encode “#” / “*” in SIP
messages that are constructed.
CSCub01162
TC/TE based TelePresence codecs configured for SIP may not register to the
expected SIP proxy server.
CSCua84565
BFCP interoperability no longer working with Jabber for Windows.

Not possible to dial via directory.
CSCtz87452
MX, EX, E20, C and SX series endpoints cannot use CUCM phone books with
numbers including spaces.

A SIP request using TCP should be responded to on the IP port where it was
received.
CSCtq72699
The Codenomicon SIP UAS test suite configured to send malformed INVITE

MXP (VCS registered) and CUCM registered endpoints such as CTS/C series.
CSCua84373
C series receive dual channel as part of main video when MCU H.239 minimum
bit rate set as 512kbps.
CSCuc69143
When TE6 is completing attended SIP transfer, E20 is receiving a second call.
CSCue16781
When dialling an MCU or other BFCP server-only endpoints after first making a
calltype: audio call, BFCP negotiation will fail because the endpoint offers s-only
which the MCU will reject.
