Conference
n Description
Conference lets an extension user add additional inside and outside callers to their conversation. With
Conference, a user may set up a multiple-party telephone meeting without leaving the office. The
XN120 Main unit provides 32 Conference circuits, to have any number of internal or external parties
conferenced up to 32. This means that one extension can Conference up to 31 internal and/or external
parties together (the originator would be the 32nd party reaching the maximum of 32).
Split (From Conference)
Split allows a user to alternate (i.e., switch) between their callers in Conference. This will allow a
dispatcher, for example, to control a telephone meeting between themselves, a customer and a service
technician. The dispatcher can meet together with all parties, privately set up a service strategy with
the technician and then meet again to set the schedule.
Split cycles through the Conference in the same order in which the Conference was initially set up. If a
user places an outside call, conferences extension 202 followed by extension 203, Split will cycle from
the trunk, to 202 and finally to 203. The Split cycle then repeats.
Barge Into Conference
If a user's extension has Barge In capability enabled, they can also Barge In on an established
Conference. This permits, for example, an attendant or supervisor to join a Conference in an
emergency. It also allows a co-worker to leave a conference -- and then rejoin the telephone meeting
when it is convenient to do so.
Transfer Call Into Conference
An extension with Barge In capability can Transfer a call into an existing Conference. This would
allow, for example, an attendant to locate co-workers and then Transfer them into an existing telephone
meeting. There is no need for the attendant to locate all the parties at the same time and sequentially
add them into the Conference.
Conditions
Conversation recording also uses conference circuits; each conversation recording will use 2
conference circuits.
Default Setting
