492 Matrix ETERNITY NE System Manual
Conference-Multiparty
What’s this?
Like the Dial-In Conference, a Multi-party conference allows speech between more than three participants. 
The key difference between Dial-In and Multi-party conference is that in a Dial-In conference participants can 
include themselves in the conference by dialing into it without assistance, whereas in a Multi-party Conference the 
party initiating the conference must include the participants by dialing their numbers and the Multi-party Conference 
feature code. 
A Multiparty conference may be 
• between extensions
• between extensions and trunks, i.e. external numbers. 
Extension users can initiate multiparty conference from a remote location using “Direct Inward System Access 
(DISA)”. 
ETERNITY NE supports 6 participants in a Multi-party Conference. The system supports 2 simultaneous Multi-
party Conferences.
How it works
A, B, C, and D are extension users.
E and F are external numbers.
A decides to hold a teleconference with B, C, D, E and F.
Initiating a Multiparty Conference
• A dials B's number and informs B about the conference call.
• A dials flash to put B on hold. B gets on-hold music.
• A dials conference inclusion code and gets confirmation tone.
• B is included in the conference.
• A goes ON-Hook and then OFF-Hook or waits for end of confirmation tone.
• A dials C's number and informs C about the conference.
• A dials flash to put C on hold. C gets on-hold music.
• A dials conference inclusion code and gets confirmation tone.
• C is included in the conference.
• A repeats the above steps to include D, E and F in the conference. 
• Having included the last participant, F, A dials conference inclusion code again.
• A is included in the conference.
• All participants can now converse.
