Conference Control Using DTMF Codes
Participants and chairpersons can manage their connection to ongoing
conferences from their endpoints, using touch-tone signals (DTMF codes)
from their endpoints. Table 3-9 lists the DTMF Codes that can be used.
Chairpersons can also control an ongoing conference using DTMF codes.
Permissions for DTMF actions to be performed by all conference
participants or by chairperson only are configured in the Conference IVR
Service assigned to the conference.
For more information, see the RMX 1500/2000/4000 Administrator’s Guide,
"Defining a New Conference IVR Service” on page 14-9 .
To use the DTMF codes to control the conference, the DTMF input must
be first enabled on the endpoint remote control (for example, entering #).
