Dial-in conferencing users can press keys on the telephone keypad to perform dual-tone multi-frequency (DTMF) commands. DTMF enables users who dial in to a conference to control conference settings (such as muting and unmuting themselves or locking and unlocking the conference) by using the keypad on their telephone. You can use cmdlets to modify the keys used for the DTMF commands. This step is optional.

To modify the key mapping of DTMF commands

  1. Open Communications Server Management Shell.

  2. Run:

    Copy Code 
    Get-CsDialinConferencingDtmfConfiguration

    This cmdlet returns the DTMF settings used for dial-in conferencing.

  3. Run the following cmdlet with the options you want to change. See the Communications Server Management Shell documentation for this cmdlet to see the list of DTMF commands you can modify:

    Copy Code 
    Set-CsDialinConferencingDtmfConfiguration

    This cmdlet modifies the DTMF settings used for dial-in conferencing.

    Note:
    You can also create additional sets of DTMF commands for specific sites. Use the New-CsDialinConferencingDtmfConfiguration cmdlet with a site identity. When you create new DTMF settings for sites, the site settings take precedence over the global settings. For details, see the Communications Server Management Shell documentation.
