Parameter Description
Web/EMS: First Call
Ringback Tone ID
CLI: 1st-call-rbt-id
[FirstCallRBTId]
Defines the index of the first ringback tone in the CPT file. This option
enables an Application server to request the device to play a distinctive
ringback tone to the calling party according to the destination of the call.
The tone is played according to the Alert-Info header received in the
180 Ringing SIP response (the value of the Alert-Info header is added
to the value of this parameter).
The valid range is -1 to 1,000. The default is -1 (i.e., play standard
ringback tone).
Notes:
It is assumed that all ringback tones are defined in sequence in the
CPT file.
In case of an MLPP call, the device uses the value of this parameter
plus 1 as the index of the ringback tone in the CPT file (e.g., if this
value is set to 1, then the index is 2, i.e., 1 + 1).
Web: Reanswer Time
EMS: Regret Time
CLI: reanswer-time
[RegretTime]
Analog: Defines 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.
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.
Web: Enable
Reanswering Info
CLI: reans-info-enbl
[EnableReansweringINF
O]
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
