Which of the following statements are correct regarding rendezvous conferences? (Choose two.)

A.
Rendezvous conferences must be scheduled.

B.
Rendezvous conferences must be configured.

C.
Rendezvous conferences are guaranteed resources.

D.
Rendezvous conferences begin as point-to-point calls.

E.
Rendezvous conferences are also called permanent conferences.

Explanation:
Rendezvous conferences must be configured, and rendezvous conferences are also called permanent
conferences. There are three basic types of conferences:
Ad-hoc
Rendezvous
Scheduled
Ad-hoc conferences are also known as unscheduled or on-demand conferences. An ad-hoc conference can be
created simply by adding a third participant to a point-to-point call. MultiSite and Multiway can be used for adhoc conferences. MultiSite uses a phone’s native multipoint control unit (MCU) functionality and allows up to
four simultaneous participants on a video call. Multiway uses a centralized Cisco MCU and Cisco Video
Communication Server (VCS); the number of simultaneous participants is limited only by the MCU. To
participate in an ad-hoc conference, simply press the Conf, Join, cBarge, or Add keys on the endpoint.
Rendezvous conferences are also called meet-me, permanent, or static conference. They can be onetime
conferences or recurring conferences. Unlike ad-hoc conferences, rendezvous conferences must be configured
and do not begin as point-to-point calls. Unlike scheduled conferences, rendezvous conferences do not need to
be scheduled and resources are not guaranteed. You can use a preconfigured alias, an MCU-interactive voice
response (IVR) dial-in, or Meet-Me to initiate a rendezvous video conference on Cisco Unified Communications
Manager (CM); Cisco VCS supports only preconfigured aliases and MCUIVR dial-ins. The conference
organizer must provide the dial-in alias or MCUIVR dial-in number to the participants.
Scheduled conferences guarantee endpoint and MCU resource availability. In addition, calendaring applications
can be used to schedule conferences. Several methods can be used to initiate a scheduled video conference
on Cisco VCS or Cisco Unified CM, including automatic connect and one button to push (OBTP). When the
automatic connect launch method is used, endpoints are automatically connected at the scheduled conference
time. When OBTP is used, conference dial-in information is displayed on endpoints that support the OBTP
feature.
