Parameter Description
advanced > reans-info-enbl
[EnableReansweringINFO]
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.
For Digital interfaces: The parameter is used for private wire services
(see Configuring Private Wiring Interworking on page 489).
[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-
90579

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 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 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
