About the Product
The PJP-MC24 is a Multipoint Audio Control Unit designed exclusively for use with
YAMAHA' s IP phone conference system “ProjectPhone.”
It manages terminal address information and routes calls between terminals. It also
manages conference schedules and automatically establishes connections between
terminals for conferencing.Equipped with the digital mixing function, the PJP-MC24
enables a voice conference with multiple participants by connecting up to 24 ProjectPhones
(or up to 96 ProjectPhones if four PJP-MC24 units are linked).
Manages address information and routes calls between
terminals
This product manages the address information of individual terminals and routes
connection requests to the appropriate recipients. Even when a terminal’s address is not
fixed (i.e. the address is assigned dynamically by DHCP), it can always be accessed
using the same dialing number. Also, even when calls are made directly between
terminals, this product functions as a SIP server and records information about the calls.
Digital mixing function
Equipped with the digital mixing function, this product is able to connect eight ProjectPhones.
By connecting two PJP-MC24 units to each ProjectPhone, up to 24 ProjectPhones can be
connected for a voice conference with multiple participants.
Link function that supports conferences of varying scales
The link function can be used to connect up to four PJP-MC24 units. When four PJP-
MC24 units are connected, four conferences, each with 24 participants, can be held
simultaneously, or one conference with 96 participants can be held.
