Enable activation/deactivation of peripheral devices and various call-handling scenarios
The FXS models support I/O ports. The two output ports enable
activation/deactivation of peripheral devices by dialing an
extension number.
A popular example of output port usage is to
open a door by dialing an extension. The four input ports create
an off hook event in Asterisk. The dial plan can be configured to
use this function to dial an extension, play a message, send an
email, activate another device using the output ports, etc.
Examples
of possible input port usage include forwarding a call
to specific numbers, and playing a pre-recorded message if the
fire/burglar alarm goes off.
For more information, see the various Asterisk application notes on this Web site.
