Conference-3 Party
What's this?
ETERNITY 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 telephone call, in which the calling party can have
two other persons participate in the call.
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 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-0.
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 ETERNITY and between extensions and external
numbers.
It is also possible to conduct an Unsupervised 3-Party Conference, wherein the operator connects two trunks
through the system and withdraws from the three-way speech.
ETERNITY NE supports two simultaneous 3-Party Conferences.
How it works
A, B, C are extensions.
D and E are external numbers.
3-Party Conference between extensions
• A is in speech with B.
• A and B want to include C in their conversation.
• A puts B on hold. A gets feature tone. B gets on-hold music.
• A dials C's extension number. A gets ring back tone.
• A is in speech with C. B cannot hear their conversation.
• A dials Flash-0 to enable three-way speech.
• A, B, and C are now in speech.
• Any of them can disconnect to withdraw from the conference.
• If C disconnects, A and B will be in two-way speech.
• A and B can carry on the conversation or can have a conference with another trunk (external number) or
with another extension.
