Description
The following video settings are not
supported with SIP connections:
•
FECC - video endpoints connect
without FECC option
•
H.264 - SIP video endpoints
connect as H.263 to CP
conferences and as Secondary in
VSW conferences
• H.239/People+Content - SIP video
endpoints can only see the video
channel and not the Content
channel
•
H.263+ Annexes
Encryption is not supported with SIP
endpoints, therefore cannot connect to
an encrypted conference.
T.120 is not supported with SIP
endpoints, hence, the video endpoints
connect without T.120.
Participant RTP/RTCP monitoring is
unavailable for SIP endpoints.
Gateway calls are not supported with
SIP endpoints.
The Welcome Slide does not appear
when a participant connects to a
Software CP conference.
The H.323 card causes an assert
when deleting a participant or
terminating a T-120 conference.
Incorrect CLI's are assigned to
undefined T1-CAS participants.
Connecting and disconnecting T1-CAS
participants can prevent the transfer of
DTMF codes from the remaining
T1-CAS participants to the MCU.
When an ISDN participant connects to
a Video Switching (Auto or H.263)
conference the endpoint disconnects.
Video card units may fail when
terminating large CP conferences
before all the participants have
disconnected from the conference.
