Caveats for CTMS Release 1.9.3
CSCui83153
Symptom: CTMS drops 1-2 endpoints from a large call when a 720 Best endpoint downgrades
quality from a 1080p Best conference.
quality from a 1080p Best conference.
Condition: Large conference (7+ endpoints).
Workaround: Dropped endpoint can dial back in.

Symptom: CTMS may crash while retrieving Media Snapshot.
Condition: The crash is observed while retrieving media snapshot.
Workaround: none.
CSCuh56345
Symptom: CTMS system crash.
Condition: The crash observed with specific pattern of call sequence. For this problem to happen,
MCU MSE 8510 or any endpoint must dial to CTS with recvonly SDP and then set the SDP to
sendrecv in REINVITE. Next, the same CTS endpoint must join the meeting on CTMS. This will
cause MediaProcess crash on CTMS due to invalid data (Num Transmit Streams: 0) in RTCP MUX
packet.

cause MediaProcess crash on CTMS due to invalid data (Num Transmit Streams: 0) in RTCP MUX
packet.
Workaround: none.
Further Problem Description: Old behavior: CTMS crashes when there is an RTCP MUX packet
with Num Transmit Streams= 0 from a CTS endpoint. New behavior: CTMS drops the call if the
RTCP MUX packet from a CTS endpoint contains Num Transmit Streams= 0. Impact to customer:
The CTS endpoint which sends invalid data (Num Transmit Streams= 0) in RTCP MUX packet
cannot join the meeting.

Symptom: CTMS system crash.
Condition: System crashes following a media control request which can be initiated when a user
checks the conference/endpoint status and performs operations such as mute/unmute from
CTX-AMM or CTMS DC page.
