SIP Actions
SIP Actions
is a mechanism by which the hardware outputs of the ARA-1 (PTT, AUXOUT0, and
AUXOUT1) may be controlled by a remote SIP endpoint. If so configured, the proper DTMF
sequence, when detected by the ARA-1’s network interface, will turn these outputs on or off.
Use the
SIP Actions
page (shown in Figure 3-4) to configure these DTMF sequences.
The
DTMF Digit Timeout
entry determines how the ARA-1 decides whether a detected DTMF
digit is part of the current DTMF sequence or the start of a new one. If the time between the end
of one digit and the start of the next is less than the DTMF Digit Timeout, that character will be
considered part of the current DTMF sequence and appended to the digits already detected. As
soon as a pause is measured that is longer than the timeout entry, the current DTMF sequence
will be considered complete. The factory default setting—a duration of one second (1000 ms)—
should work for most systems.
In order to control the PTT output of the ARA-1 using
SIP Actions
, the
Network COR Type
setting on the
Radio Settings
page (see Figure 3-5) must be set to
SIP Actions
.
