Managing MultiMedia Calling
Multimedia Call Handling
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:
— timeout 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 may be used to reach the Basic multimedia complex for voice or H.320
multimedia calls.
Enhanced Mode Operation
The Enhanced multimedia complex provides a much more tightly coupled integration of the complex
voice station and H.320 DVC system. In Enhanced Mode:
•
Both multimedia and voice calls must originate at the telephone set.
•
Voice and multimedia calls can be controlled at the telephone set.
•
Conferencing is spontaneous and established just like a voice-only conference call.
•
There is extensive support for multimedia feature interaction. Most voice features work the same
for multimedia calls.
•
Service Links can be either "permanent" or "as-needed."
