Version 6.2
For Analog interfaces: The time interval from when the user hangs up
the phone until the call is disconnected (FXS). This allows the user to
hang up and then pick up the phone (before this timeout) to continue the
call conversation. Thus, it's also referred to as regret time.
For Digital interfaces: Determines 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 value 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.
[0] Disable (default)
[1] Enable
This 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

Notes:
This parameter is applicable only if the parameter RegretTime is
configured.
This parameter is applicable only to FXS interfaces.
Enables the device to start sending and/or receiving 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
