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:

Notes:

This parameter is applicable only if the parameter RegretTime is
configured.

This 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 this
parameter, the device cancels the call by sending a SIP 408
response.
The valid value range is 1 to 600 (in seconds). The default is 180.
Note: If per trunk configuration (using TrunkPSTNAlertTimeout) is
set to other than default, the PSTNAlertTimeout parameter value is
overridden.
Enables the device to send and receive RTP packets to and from
remote endpoints without the need to establish a SIP session. The
remote IP address is determined according to the Outbound IP
Routing table (Prefix parameter). The port is the same port as the
local RTP port (configured by the BaseUDPPort parameter and the
channel on which the call is received).


[1] Transmit & Receive = Send and receive RTP packets.

