About Services

A service (also known as a meeting type) can be regarded as a meeting template. A service is the mechanism that defines the qualities and capabilities of a meeting. A service is identified by its prefix, which always starts with 6000. When Cisco Unified MeetingPlace starts a meeting, it searches for a service that has the primary characteristics (audio codecs and video bandwidth) it is looking for, and uses that service definition to determine all the other meeting characteristics.


Notes:

  • You cannot add or remove services.
  • Do not increase the bandwidth of standard rate video services beyond 384 Kbps. High rate video services must have a bandwidth setting higher than 384Kbps.
  • High capacity audio services can only use G.711 and G.729 codecs. High quality audio services must contain either G.722 or iLBC.
  • Audio codec priority has no effect when calls go through Cisco Unified Communications Manager.

The Cisco Unified MeetingPlace 3500 Series Media Server comes with six predefined services for audio and video conferencing for use with Cisco Unified MeetingPlace. The predefined services are factory tuned to be suitable in most cases for voice and video calls. We recommend starting with these services and modifying them as necessary to suit your needs.

The following sections detail how to edit specific fields in the available services.


Configuring the Maximum Call Rate

The maximum call rate represents the total bit rate of the voice, video, and data streams combined, up to a maximum of 2 Mbps per call.


WARNING: We do not recommend that you configure the maximum call rate for voice and video except under the guidance of Cisco TAC.


Procedure

  1. Click MCU on the sidebar.
  2. Click the Services tab.
  3. Select a service.
  4. Click Edit....
  5. Select the maximum call rate for the voice, video, and data streams combined for the Max call rate parameter.
  6. Click Upload.


Configuring the Maximum Layout

The Max layout parameter lists the video layout displaying the maximum number of participants to which the meeting view can expand.

The choice of layouts for the service depends on the type of processing mode. The default layout is 1+7 participants.

Procedure

  1. Click MCU on the sidebar.
  2. Click the Services tab.
  3. Select a service.
  4. Click Edit....
    The system displays a picture of the current maximum layout in the Max layout field.
  5. Click Change....
  6. Select a new layout.
  7. Click OK.


Configuring Advanced Video Settings

In the Advanced Video Settings dialog box you can configure the video codec, video image size, participant layout options, theme, and additional layouts for a particular service.


WARNING: We do not recommend that you configure the advanced video settings except under the guidance of Cisco TAC. Doing so may have unwanted repercussions to your system. For example, if you remove H.264 from the list, recordings will not include video.


Procedure

  1. Click MCU on the sidebar.
  2. Click the Services tab.
  3. Select a service.
  4. Click Edit....
  5. Click Advanced Video Settings.
    The system displays the choice of codecs that you prefer and the supported image size in the Video codecs and image size section.
    The system lists the codecs in declining order of preference, listing the most preferred codec first. Setting the codec priorities notifies the Media Server and remote endpoints of your preferred video codecs. This is useful when more than one codec is supported by both sides.
  6. Follow these steps to add or remove a codec from the Available field:
    1. Click the codec.
    2. Click Add to add it or Remove to remove it.
  7. Follow these steps to move a codec in the priority list:
    1. Click the codec.
    2. Click Up to move it up or Down to move it down.
  8. Choose the maximum incoming picture format supported in meetings using this service from the Support image size up to field.
  9. Select the layout options that you wish to define for this service from the Main (participant) layout section.
  10. Check Dynamically change layout as participants join or leave to dynamically enlarge or reduce the displayed number of subframes.
  11. Check Enable auto-switch and enter the interval in seconds to configure automatic switching. Automatic switching allows participant images in the video layout to periodically change and display other meeting participants according to the interval set.
  12. Check Display participants names and choose and option to show the name of a participant at the bottom of each sub-frame.
  13. Check Slightly reduce image size for optimal TV display to change the display from PC screen mode to TV screen mode.
  14. Check Enable `No Self See' (self image removal) to configure removal of the self image.
  15. Select a theme from the Theme to use field. Basic is the default.
  16. (Optional) Check Enable custom layouts to define custom layouts so that you can maintain backward compatibility with previous product versions.
  17. (Optional) Click Settings... to define the layout options in the Custom Layout Settings dialog box.
    Note: If you select Support presentation view (Duo Video and H.239), one of the customized layouts must be the Presentation layout.


Configuring 3G Layout Settings

In the Additional Layouts section of the Advanced Video Settings dialog box you can configure the layout options for 3G videophone users.

Procedure

  1. Click MCU on the sidebar.
  2. Click the Services tab.
  3. Select a service.
  4. Click Edit....
    The system displays the Automatic Service Definition dialog box.
  5. Click Advanced Video Settings.
    The system displays the Advanced Video Settings dialog box.
  6. Select Enable 3G videophone layout from the Additional Layouts section in order to limit the layout for 3G videophone users.
  7. Click Settings to select the layout in the 3G Layout Settings dialog box.
  8. Click Change.
  9. Select a new layout.
  10. Click OK to return to the 3G Layout Settings dialog box.
  11. Click OK to return to the Automatic Service Definition dialog box.


Configuring Advanced Audio Settings

Transcoding between audio protocols enables the Media Server to support communication between endpoints with different audio codecs. You configure service audio transcoding in the Audio Settings dialog box.

For a service, you can configure meeting audio codec support and transcoding priorities. The Media Server supports the following audio codecs:

  • G.711 A/µ law-Toll quality at 64 Kbps (A-Law/mu-Law)
  • G.722-High-quality audio at 64 Kbps
  • G.729-Audio at 8 Kbps
  • iLBC


WARNING: We do not recommend that you add or remove audio codecs except under the guidance of Cisco TAC.


Procedure

  1. Click MCU on the sidebar.
  2. Click the Services tab.
  3. Select the service.
  4. Click Edit....
  5. Click Advanced Audio Settings....
    The audio codec settings section displays the choice of codecs that you prefer for audio transcoding. The system lists the codecs in declining order of preference, listing the most preferred codec first. Setting the codec priorities notifies the Media Server and remote endpoints of your preferred audio codecs. This is useful when more than one codec is supported by both sides.
  6. Follow these steps to add or remove a codec from the Available field:
    1. Click the codec.
    2. Click Add to add it or Remove to remove it.
  7. Follow these steps to move a codec in the priority list:
    1. Click the codec.
    2. Click Up to move it up or Down to move it down.
  8. Enter the minimum audio packet size in the Audio packet size (ms) field.
  9. Enter the interval (in milliseconds) before the voice-activated video-switching mechanism displays a new active speaker in the video image in the Speaking duration to become `Active Speaker' (ms) field.
  10. Click OK.
