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, check the conference administration using the
display conference X
command 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 form 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 form to see if the
talking bit
is
y
. Next, check the
audio by standing adjacent to the microphone and speaking at a normal level.
Solution
If the audio is not muffled:
1. Use the
status conference
command to determine which port on the
TN788B (VC board) is connected to this endpoint.
2. Check the VC (TN788B) board using the
test board xxyy long
command.
3. Drop the call.
