Managing MultiMedia Calling
Feature Description
MMCH's two levels of functionality for a multimedia complex, Basic and Enhanced mode, are
enabled either by administration on Communication Manager or by an mm-basic feature button
or FAC.
Basic Mode Operation
In Basic Mode:
All voice-only calls originate at the voice station.
●
All multimedia calls originate with the H.320 DVC system.
●
All incoming voice calls attempt to alert at the voice station and receive all standard voice
●
call treatment.
All incoming H.320 multimedia calls attempt to alert on the H.320 DVC system initially. If
●
answered, a 2-way video call will result. The Basic multimedia complex voice station will
not be involved in the call in any way.
If the H.320 multimedia call is not answered at the H.320 DVC system and the Basic
multimedia complex voice station has the H.320 field administered to y, the call will:
- Time out at the DVC system.
- Alert at the associated voice station set as a voice-only call.
- Receive all standard voice call treatment.
Call control depends on what type of call is being originated.
●
- Video is received and controlled at the PC.
- Voice is received and controlled at the telephone set.
The voice station of a Basic multimedia complex must manually add their multimedia
●
endpoint to a multimedia conference. There is limited support for multimedia feature
interactions. A specific set of voice features work for multimedia calls.
Service Links are not used by Basic mode complexes.
●
A single number can be used to reach the Basic multimedia complex for voice or H.320
●
multimedia calls.
