Configure Dialing Options

You can specify video and audio dialing preferences for your system.

Procedure

  1. In the system web interface, go to Call Configuration > Dialing Preference.
  2. Configure the following settings (your changes save automatically):
    Setting Description
    Scalable Video Coding Preference (H.264) This read-only setting indicates your system uses only AVC conferencing.
    Note: Scalable video coding (SVC) conferencing isn’t supported.
    Enable H.239 Enables the use of a standards-based specification for parallel video streams (people and content). Enable this setting if you know call participants support H.239.
    Enable Audio-Only Calls Enables you to place audio-only calls on the system.
    Call Type Order Specifies an order preference for video or voice calls. Select either Video then Phone, or Phone then Video. This setting is read-only if the video system has no phone connections.
    Video Dialing Order Preferences

    Specifies how the system places video calls to directory entries with more than one type of number.

    Select one of the following protocols for each preference:

    • SIP
    • IP H.323

    This setting also determines how the system places video calls from the Place a Call screen when your set the call protocol to Auto or if it’s unavailable. For example, if a call doesn’t connect with H.323, the system tries using SIP.

    Audio Dialing Order Preferences

    Specifies how the system places audio calls to directory entries with more than one type of number.

    Select one of the following protocols for each preference:

    • SIP
    • H.323
