8.1.2 POTS monitor
Essentially, the POTS (analog) monitor provides a high
impedance tap that does not influence the interface. You
can listen to the line with the integrated handset without
having the ARGUS send on or otherwise influence the
interface.
The ARGUS displays the
voltage level on the line when
it is "on hook“ (not busy).
Start monitoring
The ARGUS displays the
voltage (when "off hook"), the
number of the caller (when
CLIP is supported) and the
DTMF characters dialed by
both telephone subscribers
and the SMSs received
(optional).

characters will be appended
