Gateway IVR Dialing For IP Participants
Can be used by IP endpoints when the destination dialing string includes the address of the MCU only. This
is the same flow as the dialing method used for ISDN/PSTN calls, however it is less recommended for IP
participants. For details, see Dialing via Gateway IVR for ISDN Participants.
