[EnableReansweringINFO]
For analog interfaces: Enables the device to send a SIP INFO
message with the On-Hook/Off-Hook parameter when the FXS phone
goes on-hook during an ongoing call and then off-hook again, within
the user-defined regret timeout (configured by the parameter
RegretTime). Therefore, the device notifies the far-
been re-answered.
For digital interfaces: The parameter is used for private wire services
(see Configuring Private Wiring Interworking on page 503).
[0] Disable (default)
[1] Enable
The parameter is typically implemented for incoming IP-to-Tel collect
calls to the FXS port. If the FXS user does not wish to accept the
collect call, the user disconnects the call by on-hooking the phone. The
device notifies the softswitch (or Application server) of the unanswered
collect call (on-hook) by sending a SIP INFO message. As a result, the
softswitch disconnects the call (sends a BYE message to the device).
If the call is a regular incoming call and the FXS user on-hooks the
phone without intending to disconnect the call, the softswitch does not
disconnect the call (during the regret time).
The INFO message format is as follows:
INFO sip:12345@10.50.228.164:5082 SIP/2.0
Via: SIP/2.0/UDP 127.0.0.1;branch=z9hG4bK_05_905924040-

interfaces.
PSTN Alert Timeout

[PSTNAlertTimeout]
Digital: Defines the Alert Timeout (in seconds) for calls sent to the
PSTN. This timer is used between the time a Setup message is sent to
the Tel side (IP-to-Tel call establishment) and a Connect message is
received. If an Alerting message is received, the timer is restarted. If
the timer expires before the call is answered, the device disconnects
the call and sends a SIP 40
8 request timeout response to the SIP party
that initiated the call.
Analog: Defines the Alert Timeout (in seconds) for calls to the Tel side.
This timer is used between the time a ring is generated (FXS) or a line
is seized (FXO), until the call is connected. For example: If the FXS
