/mcpDescription Service Parameters This parameter determines whether Unified Communications Manager chooses an encrypted audio conference bridge or an unencrypted video conference bridge for an Ad-Hoc conference call when the conference controller's Device Security Mode is set to either Authenticated or Encrypted and at least two conference participants are video-capable. Because encrypted video conference bridges are not supported in this release, Unified Communications Manager must choose between an encrypted audio conference bridge and an unencrypted video conference bridge. The default value is True. Choose Encrypted Audio Conference Instead Of Video Conference This parameter specifies the number of video-capable conference participants that must be present in an Ad Hoc conference to allocate a video conference bridge. If the number of video-capable participants is less than the number specified in this parameter, Unified Communications Manager allocates an audio conference bridge. If the number of video-capable participants is equal to, or greater than, the number specified in this parameter, Unified Communications Manager allocates a video conference bridge, when available, from the configured media resource group list (MRGL). Specifying a value of zero means that video conference bridges will always be allocated, even when none of the participants on the conference are video-capable. When a conference has been established using an audio bridge and then additional video-capable participants join the conference, the conference will remain on the audio bridge and will not convert to video. The default value is 2. Minimum Video Capable Participants To Allocate Video Conference This parameter determines whether Unified Communications Manager chooses a video conference bridge, when available, for an Ad Hoc audio-only conference call when the video conference bridge has a higher priority than an audio conference bridge in the media resource group list (MRGL). If an audio conference bridge has higher priority than any video conference bridge in the MRGL, Unified Communications Manager ignores this parameter. This parameter proves useful in situations where the local conference bridge is a video bridge (and configured in the MRGL with the highest priority) and audio conference bridges are only available in remote locations; in that situation, enabling this parameter means thatUnified Communications Manager would attempt to use the local video conference bridge first, even for audio-only conference calls. The default value is False. Allocate Video Conference Bridge For Audio Only Conferences When The Video Conference Bridge Has Higher Priority This parameter determines whether the Click-to-Conference functionality over the SIP trunk is enabled on Unified Communications Manager. The Click-to-Conference feature allows third-party applications to setup a conference using the SIP out of dialog REFER method and subscribe to the SIP trunk for Conference Event Package through SIP SUBSCRIBE/NOTIFY. Warning Enabling this parameter could negatively affect CTI applications that are not coded to support this feature.
