Conference-3 Party
What's this?
PRASAR UCS offers three types of conference calls: Conference-3 Party, “Conference Dial-In”, and “Conference-
Multiparty”.
Conference-3 Party (also referred to as Three-Way Calling) is a call, in which the calling party can talk to two other
persons simultaneously.
A 3-Party Conference is initiated by dialing the number of the first person one wishes to talk to. The first person is
informed about the conference and put on Consultation Hold. The number of the second person one wishes to talk
to is dialed. When the second person answers, s/he is informed about the conference. Three-way speech is
established by pressing Flash-*3.
An already connected two-way speech can be converted into a conference by adding a second person, without
disconnecting the call with the first person.
Thus, a 3-Party Conference may be planned or conducted on the spur of the moment.
A 3-Party Conference can be conducted with extensions of PRASAR UCS and between extensions and external
numbers.
The maximum number of simultaneous 3-Party conferences supported by PRASAR UCS is 21.
PRASAR UCS supports a maximum of 8 participants in a single or multiple conference. To increase the
number of participants in the conference, you must purchase the Conference Participant License. To
know more, refer “License Management”.
