Establishing a
Conference Call
Depending on the type of telephone you have, you can establish a
Conference Call with up to four parties, including yourself. You must be
using a telephone on the NBX system to establish the call. The other one
to three parties can be any combination of internal and external parties.
If the NBX has SIP (Session Initiation Protocol) enabled, you are limited to
three-party Conference calls, including yourself, unless your NBX system
is configured with a 3Com SIP Conference Server. For more information
on making Conference calls with SIP enabled, see your NBX administrator.
On 3Com Telephones, either press and release the hook switch or use the
Feature Code.
From a 3Com Entry Telephone, follow these steps:
1 Dial a call, or receive a call from someone else. Two parties are now on
the call.
2 While on the call, press and release the hook switch (or press Feature +
430 ). The system places the first party on hold and selects a new line.
3 Dial a call to an internal or external third party.
■
For an announced conference, wait for the third party to answer the
call, and then press and release the hook switch (or Feature + 430 )
again.
■
Until you press and release the hook switch (or Feature + 430 ) the
second time, the second party remains on hold, and you may
converse with the third party privately.
■
For a blind conference, press and release the hook switch (or Feature
+ 430 ) immediately after you dial the number. You return to the
conference, and you and the second party hear the called party’s
telephone ringing.
If the third party answers, three parties are now in the conference call.
If the third party is internal and does not answer, the attempt to
conference that party is cancelled. You cannot establish a conference call
with an NBX user’s voice mailbox.
4 Repeat steps 2 and 3 to conference in a fourth party.
