Managing MultiMedia Calling
Switching between Basic and Enhanced modes
There might be occasions when an Enhanced mode complex needs to switch to Basic mode
operation temporarily. One example is when a user wishes to make a direct point to point
multimedia call originated directly from the H.320 DVC. Basic mode operation allows this
functionality at the expense of losing multimedia call handling capabilities (i.e. hold/xfer/conf).
To switch from Enhanced mode to Basic mode, the station can either select a mm-basic feature
button or dial the mm-basic feature access code. Both of these actions are valid only if the
Enhanced mode station has no multimedia calls active.
When in Basic mode, the status lamp for the mm-basic button, if present, will be on solid. The
mm-basic feature button acts as a toggle. If the status lamp is on, when the button is selected,
the lamp will go off and the station will return to Enhanced mode. The mm-enhanced feature
access code will set the state of the station back to Enhanced. Switching to Enhanced mode is
only valid if the associated H.320 DVC system is idle.
Note:
Toggling between Basic and Enhanced mode changes the station's administered

Multimedia mode. When in Basic mode this field on the station screen will show
basic. When in Enhanced mode this field on the station screen will show
enhanced. The current station Multimedia mode will be saved to translation
when a save translation command is executed.
Forwarding of voice and multimedia calls
The Enhanced multimedia mode complex voice station can use the existing standard call
forwarding mechanisms to activate forwarding for voice calls. If the forwarding destination is on
the same server, then this will also forward multimedia calls as multimedia calls to the
destination. If the forwarding destination is off-switch, multimedia calls will forward off-switch as
voice-only calls. This is appropriate when the user will be at a location that is not able to receive
multimedia calls.
To forward multimedia calls off-switch as multimedia calls, the user must activate multimedia
call forwarding. This can be done with an mm-cfwd button or feature access code. The user
can also activate standard voice call forwarding and select the mm-call button prior to entering
the forwarding address.
Coverage
Multimedia calls to an Enhanced mode complex are subject to the same coverage criteria as
voice calls and follow the coverage path administered for the voice Station of the Enhanced
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
