Conference - Matrix Visionpro System Manual

Conference

VISIONPRO offers the facility of 3-Party Conference calls. If a user is already talking to someone and wants to
include a third person in the current conversation, he/she can create a 3-Party conference.
Following three combinations are allowed in 3-party conference:
• All three stations.
• Two stations and one trunk.
• One station and two trunks.
It is also possible to conduct an Unsupervised 3-Party Conference, wherein the operator connects two trunks
through the system and withdraws himself/herself from the three-way speech.
Suppose you are at city A. Your two colleagues are at city B and city C. Now using this feature, you staying at City
A, can make a conference call with the persons in City B and in City C. After the conference is established and if
you disconnect, then the persons in City B and in City C will be in speech with each other.
• Unsupervised conference calls are same as the DOSA calls. The unsupervised conference call shall
get disconnected after time = DOSA Inactivity Timer + DOSA Wait Timer. Hence to continue the
unsupervised conference, it is mandatory for the user to dial any digit after the warning beeps. Refer
"Direct Outward System Access (DOSA)"
• To disconnect the call it is advisable to dial '#0'.
• VISIONPRO supports maximum 2 simultaneous 3-party conferences at a time.
How it works
A, B, C are stations.
3-Party Conference between stations
• 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 station number. A gets Ring Back Tone.
• A is in speech with C.
• A dials Flash-0; a three-way speech is established.
• A, B, and C are now in a 3-party conference.
• Any of them can disconnect to withdraw from the conference.
• If C disconnects, A and B will be in a normal two-way speech.
• A and B can carry on the conversation or can have another conference with a trunk (external number) or
with a different station.
Similarly, a conference can be created including one station and a trunk or including two trunks.
