Signaling Hook
Flash Event
The ATA device can signal hook flash events to the remote
party on a connected call. This feature can be used to
provide advanced mid-call services with third-party-call-
control. Depending on the features that the service
provider offers using third-party-call-control, the following
ATA features may be disabled to correctly signal a hook-
flash event to the softswitch:
• Call Waiting Service (parameter
call waiting serv
set in the
Line tab)
• Three Way Conference Service (parameter
three-way conf
serv
set in the Line tab)
• Three Way Call Service (parameter
three-way call serv
set
in the Line tab)
You can configure the length of time allowed for detection
of a hook flash using the Hook Flash Timer parameter on
the Regional tab of the administration web server. See
“ATA Voice Field Reference,” on page121.
Configurable Dial
Plan with Interdigit
Timers
The ATA device has three configurable interdigit timers:
Initial timeout (T)—Signals that the handset is off the hook
and that no digit has been pressed yet.
Long timeout (L)—Signals the end of a dial string; that is,
no more digits are expected.
Short timeout (S)—Used between digits; that is after a
digit is pressed a short timeout prevents the digit from
being recognized a second time.
See “Configuring Dial Plans,” on page 61 for more
information.
Polarity Control The ATA device allows the polarity to be set when a call is
connected and when a call is disconnected. This feature is
required to support some pay phone system and
answering machines. Polarity Control is configured in the
Line and PSTN Line tabs. See “ATA Voice Field Reference,”
on page121.
