Figure 19. Media Center Configuration for
DTMF
classroom
Caller
ID
or Intercept Zone with
DTMF
Classrooms and
DTMF
Cards
When teamed with a phone system that can produce pure
DTMF
tones (like
Telecenter
®
V or Telecenter
®
System 21) the
RANGER
system can process caller
ID
messages (as long as those messages are in the form of
DTMF
tones) to determine
which classroom requires media control.
The information about the classroom is placed into the classroom database, but
since the
DTMF
card in the
RANCC16
rack is not assigned to any given classroom (it
is available to all classrooms), the “Control Address” field holds the telephone
extension number of the classroom.
In order for this to work, a new section must be added to your Mediapc.ini file. Use
the following as an example.
[
DTMF
]
callerID=1
header_length=3
extension_length=3
extension_start=1
Num_DTMF_Cards=x
DTMF_Card_1=14
DTMF_Card_2=19
∫
DTMF_Card_x=47
