2. At the appointed time, the conference controller calls his or her telephone from the
multimedia endpoint by dialing the 1-number extension. Once this call is established, the
controller conferences in other calls as if this were a voice conference. The controller
continues to add conferees in this manner until all conferees have joined, or until the
number of conferees reaches the administered limit.
3. The conference controller can also add voice or multimedia parties to the conference
spontaneously. The controller presses CONFERENCE, makes a voice or multimedia call to
a new party. To make a multimedia call, the controller must originate a call using the
mm-call button or FAC or the mm-multinbr button or FAC. After the new party begins
alerting, the controller can press CONFERENCE to add the party to the existing conference
call on hold.
Coverage
Multimedia calls to a Basic mode complex are subject to the same coverage criteria as voice
calls and follow the coverage path administered for the voice station of the Basic multimedia
mode complex.
If a plain voice station or a Basic mode complex is the covering party, the answering voice
station will receive audio only. If all voice stations in the coverage path have the station screen
Early Answer field set to n and the originator of the multimedia call was not a local Enhanced
mode complex, the answering station will hear hourglass tone.
If an Enhanced mode complex is the covering party, the answering voice station will receive
voice and video. If all voice stations in the coverage path have the station screen Early Answer
field set to n and the originator of the multimedia call was not a local Enhanced mode complex,
the answering station will hear hourglass tone.
Coverage: Multimedia calls and off-net call coverage
If the principal station's coverage path include a remote coverage point, the multimedia call will
cover off-switch as voice only. If the call is unanswered off-switch and proceeds to the next
coverage point on-switch, the multimedia nature of the call is preserved.
Coverage: Multimedia calls and coverage to voice mail
Voice mail systems such as AUDIX are typically the last point in a coverage path and are
usually implemented as a hunt group. In order to guarantee that the originator of an H.320
multimedia call hears the voice mail greeting, the hunt group that defines the list of voice mail
ports should have the Early Answer field on the hunt group set to y. This field will have no
effect on voice calls to the voice mail system.
