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).

[0] Disable (default)

[1] Transmit & Receive = Send and receive RTP packets.

[2] Transmit Only= Send RTP packets only.

[3] Receive Only= Receive RTP packets only.
Notes:

To activate the RTP Only feature without using ISDN / CAS
signaling, you must do the following:
