Answering a call
An incoming call rings on the telephone set connected to the GT1524 (and speaker, if
one is connected to the GT1524) and causes the On LED to flash. There are four
ways to answer an incoming call:
To answer a call
You can answer a call using any of the following methods:
• Press the On button on either the front panel or on the remote control. This
will route the call through the GT1524.
• Pick up the telephone handset and talk to your party over the telephone.
Press the front panel On button to connect the call to the GT1524.
• Use external control such as an AMX or Crestron touch panel or custom
control device. See page 21 for information on using serial commands.
Making a call
Call the party using your handset. After the other party has answered, route the call
through the GT1524 by pressing the On button.
The On LED lights and the GT1524 takes control of the call, disabling the
telephone set. You can now safely hang up the handset without disconnecting the
call or access the DTMF dialer in the GT1524 via a remote control system.
Disconnecting a call
If the call is routed through the GT1524 (the On LED glows green), press the Off
button on the front panel or send a command through the RS-232 port (TE 0). The
Off LED glows red, and the On LED turns off.
If Auto-Answer is turned
On under System settings,
the GT1524 answers the
call after the second complete ring.
A ringing tone is provided to the
Line and Speaker output if Ring
Indication is turned on.
When using the DIAL
serial port command, the
GT1524 automatically
engages the hybrid. You do not need
to press the On button.
If Auto-Disconnect is
turned On in System
settings, the GT1524
disconnects upon sensing loop drop
or call progress tones.
