Conference Calls
A conference call is a conversation involving 2 or more remote parties. In order to start a conference, there must be
at least two calls with at least one in the connected state and one in the holding state. The following figure shows
such a scenario with two calls in progress. To start a conference, highlight one of the calls in the holding state and
press the “Add to Conf” soft key.

call by highlighting the holding call and selecting Add to Conf
The OBi1000 phones support two methods to conference multiple parties:
a)
Local mixing/bridging
: the conference call is mixed locally by the phone
and
b)
External conference bridge
: The conference call is mixed by an external conference bridge. In this case the
options shown on your phone may be different. Check with your administrator for further details.
Local Mixing/Bridging
The OBi supports up to 4-‐way conferencing (with 3 remote parties) using the local mixing/bridging method. After
starting a 3-‐way conference call the user can see the two remote parties both in the connected state, as shown in
the following figure.
Figure 22: A locally-‐mixed conference call in progress
There are two ways to add a third remote party, either make a new call to the target party or answer a new
incoming call from another remote party.
To make a new call to the target party, either press the “more” soft key and select the “conference” option, or press
an available and inactive call key. In the event that the remote party places an incoming call to the user, the OBi will
automatically place the two currently connected calls on hold. When the target party rings or answers, resume the
two original conferencees one at a time by highlighting each holding call on screen and applying the “Add to Conf”
option to it. Now, you will have a 4-‐way conference with three calls in the connected state.
