Multimedia Call Handling

Multimedia Call Handling

DEFINITY ECS enables you to administer two devices as a multimedia call com- plex. Composed of a voice terminal and a personal computer and/or data mod- ule, the complex handles both voice and video calls. Multimedia calls are treated in much the same manner as are voice calls. The user can:

■Forward calls

■Cover calls

■Hold calls

■Park calls

A multimedia complex is also useful for conducting video conferences. The ser- vice circuits that support MMCH are in multiple port networks and allow for increased simultaneous calls.

Multimedia call handling requires that the transmission endpoints comply with the ITU H.320 standard for visual telephone systems. Specifically, it has been tested with the following multimedia transmission equipment:

■PictureTel

■Proshare

■Vistium

■Zydacron

Multimedia call-handling features the following capabilities:

■One number access — Allows users to dial only one number to access the multimedia complex, regardless of the type of call. In MMCH, DEFINITY ECS recognizes whether the call is multimedia or voice, and routes it to the appropriate device in the complex — telephone or PC (or data module).

■Multimedia to voice conversion — If a multimedia call cannot be handled by the PC or data module in a multimedia complex for some reason, DEFINITY ECS converts it to a voice call and sends it to the telephone.

■Call redirection — Calls to the multimedia complex can be redirected to coverage (AUDIX Voice Messaging, for example) or forwarded. Multimedia calls sent to coverage are first converted to voice calls. Multimedia calls that are forwarded to telephones are also converted to voice calls. Multimedia calls that are forwarded to a multimedia station or complex are not converted to voice calls.

■Call-Me Conferencing — You can use the multimedia complex telephone to control multimedia conferences. All the conference participants must call the controlling telephone. The telephone must remain connected to the conference for the duration of the conference.

■Call association — The second call of a 2 B-channel call is automatically matched with the first call and routed to the same multimedia complex.
