This dialler is the one used in our control room systems
The dialler allows dialling direct from the application.
Either a normal telephone can be connected to the
dialler or a optional headphone may be used.
For telephone the number may be dialled direct from the
application,
the call progress is monitored on the supplied speaker then
the call is answered by lifting the telephone.
With the headphone the call is received automatically
through the headset.
