Version 7.2 1089 Mediant 500L Gateway & E-SBC
User's Manual 69. Configuration Parameters Reference
Parameter Description
Note: The parameter is applicable only when the IsFaxUsed
parameter is set to 2, and for re-INVITE messages generated by the
device as result of modem or fax tone detection.
First Call Ringback Tone ID
configure voip > sip-
definition settings > 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 the parameter).
The valid range is -1 to 1,000. The default is -1 (i.e., play standard
ringback tone).
Note:
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 the 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).
Reanswer Time
configure voip > sip-
definition settings >
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.
Enable Reanswering Info
configure voip > gateway
advanced > reans-info-enbl
[EnableReansweringINFO]
For analog interfaces: 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-
been re-answered.
[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
From:
<sip:+551137077803@ims.acme.com.br:5080;user=phone>;tag=00
8277765
To: <sip:notavailable@unknown.invalid>;tag=svw-0-1229428367
