conversation. Thus, it's also referred to as regret time.
Digital: Defines the time period the device waits for an MFC R2 Resume
(Reanswer) signal once a Suspend (Clear back) signal is received from
the PBX. If this timer expires, the call is released. Note that this is
applicable only to the MFC-R2 CAS Brazil variant.
The valid range is 0 to 255 (in seconds). The default is 0.
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-end that the call has been re-answered.

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_905924040-90579

The parameter is applicable only if the parameter RegretTime is
configured.

The parameter is applicable only to FXS interfaces.
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 408 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
device receives an INVITE, it generates a ring to the phone and sends
a SIP 180 Ringing response to the IP. If the phone is not answered
within the time interval set by the parameter, the device cancels the call
