32. CONFERENCE CALLS
32.1 Station 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 station, the confer-
ence can include any combination of up to three intercom and/or outside calls. The CPC or
CPU provides 12 conference channels (24 on a triple- or quad-chassis system). Additional
channels can be added, via DSP programming on the Options card, to support conferencing.
NOTE: During a conference, some reduction in voice volume may be noticed, depending on
CO trunk quality.
32.2 During a conference, if any station user presses a keypad button, the DTMF tones will
be heard by all other parties in the conference. This allows conference callers access to DTMF-
controlled devices.
32.3 An established conference can be transferred to another station, using the call transfer
feature described on page 5-207. While the transfer is taking place, the parties in the confer-
ence remain connected to each other and may converse. The transfer will appear at the destina-
tion station in the same manner as any other transferred call along with a CONFERENCE TFR
FROM (username) display and may be answered by the party.
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 not vulnerable to unauthorized intrusions. If
the central office [local exchange] 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 phone
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 station or when a call is in an unsupervised conference.
32.4 In a network setting, a user can build a conference with party members (stations 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.
