Problems During a Video Conference

Problem (For load-balancing configurations only) The voice and web conferences are up and running but the video conference is unavailable.

Solution The Cisco MeetingPlace web-conferencing server on which

Cisco MeetingPlace Video Integration is installed may have been down or unavailable at the start of a conference. If this happens, the meeting rolls to a server on which Cisco MeetingPlace Video Integration is not installed, and video conferencing is not possible for this conference. See Configuring Load-Balancing Configurations for Video Conferencing, page 3-12.

Problem Error message when dialing out to a video endpoint: Error:[513] A video call is already in

progress. Please wait for the call to complete.

Solution The E.164 number that the user has specified in the Connect dialog box is associated with an endpoint that is already participating in the video conference, or is currently being called.

Problem User trying to dial in to a conference hears a message that the call has been rejected.

Solution The video conference is not in session, or resources are not available to accommodate the participant.

Problem The option to join the video conference is not available from within the web conference.

Solution In a DMZ or load-balancing configuration, if the conference is held on a server that

Cisco MeetingPlace Video Integration is not installed on, video conferencing is not available for that conference.

Problem No video-conferencing ports are available, but ports should be available.

Solution

•Make sure SCCP services are not using ports you expect to be available to Cisco MeetingPlace. SCCP and H.323 share the resources on the Cisco IPVC MCU.

•If this happens frequently, examine usage patterns using the reporting tools described in About Video-Conferencing Statistics, page 4-13and change the settings for floater and overbook ports using the calculations in About Configuring Port Parameters, page 4-7.

Problem The video image is transmitted, but no audio is transmitted.

Solution

•Make sure the video endpoint is not muted at the endpoint.

Problem The audio channel from the video endpoint is transmitted, but no video image is transmitted.

Solution
