No Switching, Full Motion Video
If a room is excessively noisy, the Avaya MultiVantage Software MMCH may
receive sufficient audio signal to conclude that there is a speaker present. Use the
Status Conference x screen to determine if the MMCH thinks an endpoint is
talking. The MMCH sets the
Ts
field to
t
for each endpoint if there is voice
energy detected. This endpoint may have to mute when nobody at the site is
speaking to allow the conference to proceed normally. Remind the customer that it
may be necessary to mute if a side conversation is going on in the background,
just as one would do in an audio conference. If the system does not switch
broadcasters even after the current broadcaster has muted, type display
conference X to ensure that the conference is in voice-activated mode. Also
verify that parties who were speaking are valid video sources as described in the
“
Calls Terminate with No Video ” section above.
The See-Me feature (MCV) can also cause VAS to “lock-up.” An endpoint can
activate MCV to force their site to become the broadcaster. If they do not disable
the feature when finished, the system remains in this mode indefinitely. Beginning
with Release 3.0, the status conference X command shows that MCV is in effect
by displaying
av
in the Video Status (Vs) column. Page 3 of the Status
Conference X Endpoint Y screen also has a
Broadcaster
field that indicates
MCV is in effect with (SEE-ME) as the broadcaster. The same scenario can occur
in a CHAIR or UCC-controlled conference with a designated broadcaster. In this
situation the CHAIR/UCC has not released the designated broadcaster and
returned to VAS mode. If there is a UCC-designated broadcaster, status
conference X indicates a Video Status of
u
. Also, for UCC rollcall the return video
may appear to be stuck. Check the Video Status for an “
R
,” indicating rollcall.
If none of the examples above appears to be the cause, and if the room was quiet,
all speakers are valid video sources, the conference is voice-activated, and the
speaker can be heard, then escalate the problem.
Video Never Switches to a Particular Party
Description
Verify that the endpoint is a valid video source as described in the “ Calls
Terminate with No Video ” section above. If it is, then the audio from the endpoint
may not have sufficient voice signal for the hardware to determine the parties at
the endpoint are speaking. Check the
Talk
field on page three of the Status
Conference X Endpoint Y screen to see if the
talking bit
is
y
. Next, check the
audio by standing adjacent to the microphone and speaking at a normal level.
