Conferencing
Calls
A conference call between two or more parties can be set up.
Note that:
 Only 3-way conferences are supported.
 Any participant of the conference can put the conference
on hold and make other calls. This participant may then
rejoin the conference at a later time by unholding it. The
participant that has initiated the conference cannot put
the conference on hold.
This assumes that your system administrator has properly enabled the
Conference service.
Requirements For the conference call to occur successfully, all parties must meet the
following requirements:
 Support at least one of the PCM codecs (G.711 µ-law
and G.711 A-law) enabled on the line that is having the
conference.
 Ability to dynamically change codec during a call.
 The packetization period (ptime) should be the same for
all the partcipants of the conference. If this is not the
case, then part of the conversation may be lost, resulting
in a choppy voice. For better results, Mediatrix Telecom,
Inc. recommends to set the packetization period of all
participants of a 3-way conference to 30 milliseconds.
