SIP User's Manual 10. Configuration Parameters Reference
10.12.7 Tone Parameters
This subsection describes the device's tone parameters.
10.12.7.1 Telephony Tone Parameters
The telephony tone parameters are described in the table below.
Table 10-53: Tone Parameters
Parameter Description
Web/EMS: Dial Tone Duration [sec]
[TimeForDialTone]
Duration (in seconds) that the dial tone is played.
FXS interfaces play the dial tone after the phone is picked up
(off-hook). FXO interfaces play the dial tone after the port is
seized in response to ringing (from PBX/PSTN).
The valid range is 0 to 60. The default time is 16.
Notes:
 During play of dial tone, the device waits for DTMF digits.
 This parameter is not applicable when Automatic Dialing is
enabled.
Web/EMS: Stutter Tone Duration
[StutterToneDuration]
Duration (in msec) of the Confirmation tone. A Stutter tone is
played (instead of a regular dial tone) when a Message
Waiting Indication (MWI) is received. The Stutter tone is
composed of a Confirmation tone (Tone Type #8), which is
played for the defined duration (StutterToneDuration) followed
by a Stutter Dial tone (Tone Type #15). Both these tones are
defined in the CPT file.
The range is 1,000 to 60,000. The default is 2,000 (i.e., 2
seconds).
Notes:
 This parameter is applicable only to FXS interfaces.
 If you want to configure the duration of the Confirmation
tone to longer than 16 seconds, you must increase the
value of the parameter TimeForDialTone accordingly.
 The MWI tone takes precedence over the Call Forwarding
Reminder tone. For detailed information on MWI, see
Message Waiting Indication on page 262.
Web: FXO AutoDial Play BusyTone
EMS: Auto Dial Play Busy Tone
[FXOAutoDialPlayBusyTone]
Determines whether the device plays a Busy/Reorder tone to
the PSTN side if a Tel-to-IP call is rejected by a SIP error
response (4xx, 5xx or 6xx). If a SIP error response is
received, the device seizes the line (off-hook), and then plays
a Busy/Reorder tone to the PSTN side (for the duration
defined by the parameter TimeForReorderTone). After
playing the tone, the line is released (on-hook).
 [0] = Disable (default)
 [1] = Enable
Note: This parameter is applicable only to FXO interfaces.
