proceed normally. Remind the customer th at it may be necessary to mute if a
side conversation is go ing on in the backg round, just as one would d o in an
audio conference. If the system does not switch broad casters even after the
current broadcaster has muted, check the c onference administration using the
display conference X command to ensure that the c onference is in
voice-activated mod e. Also verify that parties who we re speaking are valid vid eo
sources as describ ed in the “Calls Terminate with No Video” section above.
The See-Me feature (MCV) can also cause VAS to “lock-up.” An endp oint can
activate MCV to force their site to bec ome the broadcas ter. If they do not disab le
the feature when finished, the system remains in this mode ind efinitely. 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 indic ates MCV
is in e ffec t with (SEE-ME) as the broa dc aster . The s ame sc ena rio c an oc cur in a
CHAIR or UCC-controlled conference with a d esignated broad caster. In this
situation the CHAIR/UCC has not released the designated broadcaster and
returned to VAS mode. If there is a UCC-designated broad caster, status
conference X indicates a Video Status of u. Also, for UCC rollc all the return
video may appear to be stuck. Check the Video Status for an “R,” indicating
rollcall.
If none of the examples above ap pears to be the cause, a nd if the room was
quiet, all speakers are valid video sources, the conferenc e is voice-activated ,
and the speaker can b e heard, then escalate the p roblem.
Video Never Switches to a Particular Party
Description
Verify that the endpoint is a valid video sourc e as describ ed in the “Calls
Terminate with No Video” section above. If it is, then the audio from the endpoint
may not have sufficient voice sig nal for the hardware to determine the p arties at
the endpoint are speaking . Check the Talk field on p age 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 microp hone and speaking at a normal level.
Solution
If the audio is not muffled:
1. Use the status conference command to determ ine 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.
