Placing a Conference Call

Conference Calls
Users can establish multi-party conference calls without operator assistance. There can be up
to four parties in a conference. In addition to the initiating endpoint, the conference can include
any combination of up to three intercom and/or outside calls.
During a conference, if any user presses a dialpad button, the DTMF tones will be heard by all
other parties in the conference. This allows conference callers access to DTMF-controlled
devices.
Using the call transfer feature described on page 164, an established conference can be trans-
ferred to another endpoint. While the transfer is taking place, the parties in the conference
remain connected to each other and may converse. The transfer will appear at the destination
endpoint in the same manner as any other transferred call along with a CONFERENCE TFR
FROM (username) display and may be answered by the party.
In a network setting, a user can build a conference with party members (endpoints and/or
trunks) on other nodes. The conference circuits used to build the conference will be allocated
from the originating party’s node. Any party, not just the originating party, can add a party
member to the conference.
• If the party who adds the new member is on the originating party’s node, the party will
be added to the conference circuit already allocated. This conference is still restricted to
the four party limit.
• If the party who adds the new member is not on the originating party’s node, a new con-
ference circuit is allocated from the second node. Because this allows more than four
parties in a conference, users should be warned that voice levels can be degraded as
more parties are added to the conference.
Placing a Conference Call
To place a conference call while on a call with an Inter-Tel endpoint:
1. Press the button, or press the Special button and enter the Conference feature
code (5). The party is on conference wait hold (hears music) and the button
flutters. The display shows CALL NEXT PARTY TO CNF.
To place a conference call while on a call with a single line endpoint:
1. Hookflash and enter the Conference feature code (5). The party is on conference wait
hold (hears music).
2. Place an intercom or outside call to another party (or return to a call on hold) to be
included in the conference.
NOTE
During a conference, some reduction in voice volume may be noticed, depending
on CO trunk quality.
NOTE
While this system is designed to be reasonably secure against CO trunk misuse
by outside callers, there is no implied warranty that it is invulnerable to unautho-
rized intrusions. If the central office does not provide supervision, and does not
disconnect the call when one party hangs up, making it possible for a caller to
remain connected to a CO trunk circuit. If this happens, and the caller begins
dialing, the call could be placed through the system and would then be billed to
the system's owner. The system cannot check this type of call for toll restriction
and may not register the call in SMDR. This problem could arise when a call is
connected to a endpoint or when a call is in an unsupervised conference.
NOTE An existing conference is not a valid “party” for another conference.
