MCU to MCU Calls via ISDN Cascading Link
A dial out ISDN participant is defined (added) to conference A running on MCU A. The
participant’s dial out number is the dial-in number of the Entry Queue or conference
running on MCU B (for example 54145106).
MCU A dials out to an Entry Queue or conference B running on MCU B using the Entry
MCU A dials out to an Entry Queue or conference B running on MCU B using the Entry
Queue number (for example 54145106) or the conference number.

When the participant, who is a dial-in participant in conference B, connects to the Entry
Queue, the system plays to all the participants in Conference A the IVR message requesting
the participant to enter the destination conference ID (or if connecting to a conference
