Telephony Standard View
OptiCall™ may be used in one of the following four operating modes:
•
Loop
•
Origin
•
Termination
•
Terminate All
In the loop mode, one instance of OptiCall™ controls both, the originating as
well as the terminating side of a connection. Both sides must be connected to
the same OPERA™ system.
If set to the Origin mode, OPERA™ is connected to just the originating side of a
connection. OptiCall™ will initiate a phone call on the specified interface and
start transmission as well as recording of the audio data as soon as the call is
answered by the terminating side (which may be another OPERA™ system, or
just another instance of OptiCall™ running on the same machine).
In the Termination mode, OPERA is connected to just the terminating side of a
connection. OptiCall™ will wait for an incoming call on the specified interface
and start transmission as well as recording of the audio data immediately. The
origin of the call may be another OPERA™ system, or again just another instance
of OptiCall™ running on the same machine.
The terminate-all-mode does exactly what the Termination mode does. The
only difference is that the system will wait for incoming phone calls on any of
