2.15.1 Conference Group Call
Additionally, extension users not registered in the called conference group can join a conference after it has
started. Outside callers using DISA and TIE line users can also join a conference after accessing their
extension using Walking COS.
An entry code can also be specified to restrict access to the call. The entry code can be set when the caller
initiates the conference group call. If an entry code is to be set, usually the caller will inform call participants
in advance.
[Starting a Conference Group Call using Hands-free Answerback]
Hands-free Answerback can be enabled for conference group member extensions. By initiating a
conference group call with a conference group that includes an extension that has Hands-free Answerback
(→ 2.4.4 Hands-free Answerback) enabled, such as a softphone, the call can be automatically answered
and the conference begins with only one participant (the initiator of the conference group call). Then, up to 6
participants can use Join After Time Out to join the conference. For example, a manager can organise a
meeting where all the members are calling from cellular phones and use Join After Time Out to join the
conference.
