Enabling conference DTMF for multi-party calls

Account owners and admins can enable or disable the Conference DTMF option for multi-party conference calls. When this setting is enabled, users can interact with automated systems, input access codes, or perform other functions without disrupting the call. When they add other participants to a call, the current callers will hear the dialing, DTMF, and voicemail associated with the new call process. This functionality is available for regular conference calls (not conference barge) and the Zoom app.

Account owners and admins can also enable the No Hold Conference setting in addition to this setting.
