Conference with more than three participants

Required: A three-way conference must be in
progress.
In a conference with more than three participants the
extension that began the conference (master exten-
sion) may administrate up to 5 new participants (slave
extensions).
• Adding a participant;
• Removing a participant;
• Leave the conference;
• End a conference;
Considerations:
• If the master replaces the telephone on the hook or
an error occurs during the consultation, a callback is
begun for the conference.
• When an external call is received, the master can
temporarily leave the conference, answer the call
and add that new participant to the conference. If it
is a slave extension, it can answer the call with the
telephone menu, but it will then be disconnected
from the conference.
• The maximum number of conference calls (includ-
ing override and silent monitoring) is two, as one ex-
tension cannot take part in both at the same time.
• In the HiPath 1190 there is an upper limit of 16 lines
configured with the CLIP DTMF option that causes
limitations in the conference feature depending on
the number of lines being used by the CLIP DTMF
at any given time. This is caused by the fact that
both the CLIP DTMF and the Conference use com-
mon resources in the system.
So, for example:
– In a system with 16 CLIP DTMF lines there can be
2 conferences with 3 participants;
– In a system with 8 CLIP DTMF lines there can be
1 conference with 8 participants or 2 conferences
with 4 participants;
– In a system with no CLIP DTMF lines there can be
2 conferences with 8 participants.
To free additional ports for use with the Conference
feature without depending on the use of the CLIP
DTMF , this function should be disabled for certain
lines. (see Manager or Programming Manual*, Ana-
log Identification - CLIP).
