Figure 29: 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” optio
n, 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.
External Conference Bridge
When using an external conference bridge, the conference size is not limited by the phone but by the conference
bridge. Check with your phone administrator or service provider on the size limit. Earlier, we described how to start
a 3-way conference, however, after the conference is started, you will notice that only one connected call to the
conference bridge remains on the screen while the two calls with the initial two conferencees are removed. This
indicates the two conferencees have also connected to the conference bridge on their own.
To add another conferencee, make a new call to the target number or answer a new incoming call from another
party - this will automatically hold the current call to the conference bridge. When the called target rings or
answers, highlight the call to the conference bridge that is currently in the Holding State
and select the “Add to
Conf” option. At that point the call to the conference bridge is resumed while the new remote party is also added to
the conference bridge. You can continue to add more conferencees this way until it reaches the limit set by the
conference bridge.
Group Paging
A paging group is a multicast group such that every phone on the same LAN that has joined the group can send
audio to and receive audio from other members of the group. A multicast group is defined with a multicast address.
Each OBi1000 phone supports two multicast groups that are configurable by the administrator. The administrator
may also assign a feature key for users to join or leave each group. Consult your phone administrator to check
whether the group paging feature is enabled at your location.
In most cases, adding the “Page Group” feature key will enable group paging using the default settings. Simply add
page group 1 or 2 to each phone as required.
Here is how to use the group paging feature:
1.
If not joined (LED off), press the key once to join the paging group. Once you have joined, the LED is red and
your phone will play audio received from the paging group (multicast channel)
2.
After joining (LED red), press and hold down the key to talk (PTT or push-to-talk) to the group. Audio
received from the multicast channel is paused while you are talking
