6.11 Tone Parameters
This subsection describes the device's tone parameters.
6.11.1 Telephony Tone Parameters
The telephony tone parameters are described in the table below.
Table 6-47: Tone Parameters
Parameter Description
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.
Stutter Tone Duration
[StutterToneDuration]
Duration (in msec) of the Confirmation tone. A Stutter tone is
played (instead of a regular dial tone) when Call Forward is
enabled on the specific port or 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, refer to
Message Waiting Indication on page 428.
Web: FXO AutoDial Play
BusyTone
[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.
