Examples
# Configure the amplitude of DTMF tones as –8.0 dBm.
<Sysname> system-view
[Sysname] voice-setup
[Sysname-voice] dtmf amplitude -8.0
dtmf sensitivity-level
Use dtmf sensitivity-level to set the DTMF detection sensitivity level.
Use undo dtmf sensitivity-level to restore the default.
Syntax
dtmf sensitivity-level { high | low | medium [ frequency-tolerance value ] }
undo dtmf sensitivity-level
Default
The DTMF detection sensitivity level is low.
Views
FXS interface view, FXO interface view
Predefined user roles
2: System level
Parameters
high: Sets the DTMF detection sensitivity level to high. In this mode, the possibility of missing a true DTMF
tone is low, but the possibility of false detection is high.
low: Sets the DTMF detection sensitivity level to low. In this mode, the possibility of false detection is low,
but the possibility of missing a true DTMF tone is high.
medium: Sets the DTMF detection sensitivity level to medium.
frequency-tolerance value: Specifies the absolute frequency deviation (in percentage) when the DTMF
detection sensitivity level is medium. The value range is 1.0 to 5.0, and the default is to 2.0. The greater
the value, the higher the probability of false detection.
Examples
# Set the DTMF detection sensitivity level to high for voice interface 1/0.
<Sysname> system-view
[Sysname] subscriber-line 1/0
[Sysname-subscriber-line1/0] dtmf sensitivity-level high
dtmf time
Use dtmf time to configure the duration of DTMF tones and the interval between DTMF tones.
Use undo dtmf time to restore the default.
Syntax
dtmf time { interval | persist } milliseconds
