Problems During a Video Conference

Problem No video when joining a video meeting with Cisco VT Advantage.

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 directional microphone available.

•If connected via both a video endpoint with a microphone and a telephone, or more than one audio device of any kind, mute or hang up all but one device.

•If your network uses Cisco CallManager, turn off silence suppression (the comfort noise) in Cisco CallManager.

•Configure all endpoints to optimize sound quality, according to the documentation that came with the endpoint. Cisco Systems cannot provide technical support for third-party endpoints.

•If other solutions do not solve the problem, try muting 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 plugged 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 phone (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 than 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 IPVC MCU. The Voice Activated view should be set to All see one.

Problem Multiple video links are established.
