Problems During a Video Conference
Problem No video when joining a video meeting with Cisco VTAdvantage.
Solution Make sure the video codecs match on the Cisco IPVC MCU and Cisco CallManager.
Problem Only View Active Speaker is available; users cannot choose to View Multiple People.
Solution
•If the Cisco IPVC MCU has only an MP card and not an EMP card, and the MCU is configured to
allow SCCP endpoints to attend the conference, all participants can view only the current speaker.
•If the Cisco IPVC MCU has an EMP card, make sure the Continuous Presence view has been set
correctly. See Setting Conference View Parameters, page 3-8.
Problem Poor sound quality, static, or echo coming from the video endpoint.
Solution These issues are not related to Cisco MeetingPlace. Possible solutions:
•Minimize background noise by choosing a quiet location and using the most direc tional microphone
available.
•If connected via both a video endpoint with a microphone and a telephone, or more than one audi o
device of any kind, mute or hang up all but one device.
•If your network uses Cisco CallManager, turn off silence suppres sion (the comfort noise) in
Cisco CallManager.
•Configure all endpoints to optimize sound quality, according to th e documentation that came with
the endpoint. Cisco Systems cannot provide technical suppo rt for third-party endpoints.
•If other solutions do not solve the problem, try mu ting the audio channel of the video endpoint at
the endpoint, then connect to the conference via telephone.
For desktop video endpoints, try the following in addition to the previous items:
•Reduce the input gain (volume) of the endpoint that is generating unwanted noise.
•Increase the output volume of an endpoint that is not loud enough.
•The microphone built into most computers generally has poor sound quality. We recommend using
an external microphone instead.
•There may be multiple microphones sending signal from a single user. Check for a microphone on
the computer, a microphone on the video camera, and an external microphone plugg ed in to your
audio card. Turn off all but one.
•Use a headset with a directional microphone.
•Do not use a desktop video endpoint and a soft p hone (such as Cisco VT Advantage and Cisco
Communicator) on the same system to attend a single conference.
•Software-based endpoints generally have lower sound quality t han Hardware-based endpoints.
Problem The video image does not update to the current speaker.
Solution
•The current speaker may not be video-enabled.
•Check settings in the Cisco IPVCM CU. The Voice Activated view should be set to All see one.
Problem Multiple video links are established.
Solution You have specified an incorrect E.164 address in CiscoM eetingPlace VideoIn tegration. To
