Usage guidelines
Increasing the number of busy tone detection periods can improve the detection accuracy to reduce the
likelihood of false on-hook, but it increases the likelihood of failed on-hook.
Test the new value multiple times to make sure the new value does not cause failed on-hook.
Examples
# Set the number of busy tone detection periods to three.
<Sysname> system-view
[Sysname] subscriber-line 2/2/1
[Sysname-subscriber-line2/2/1] busytone-detect period 3
busytone-hookon delay-timer
Use busytone-hookon delay-timer to configure the delay time from when an FXO interface detects a busy
tone to when the interface goes on-hook.
Use undo busytone-hookon delay-timer to restore the default.
Syntax
busytone-hookon delay-timer value
undo busytone-hookon delay-timer
Default
The delay time is 0 seconds (the FXO interface goes on-hook immediately after detecting a busy tone).
Views
FXO interface view
Predefined user roles

Parameters
value: Specifies the delay time in the range of 0 to 30 seconds.
Usage guidelines
An FXO interface goes on-hook when detecting a busy tone. This will cause the user of the IP phone
connected to the FXO interface to mistake the on-hook as a line problem because the user cannot hear
the busy tones.
To resolve this problem, use this command to configure an on-hook delay so the user of the IP phone can
hear the busy tones during the delay time.
Examples
# Set the delay time from when FXO interface 2/2/1 detects a busy tone to when the interface goes
on-hook to 3 seconds.
<Sysname> system-view
[Sysname] subscriber-line 2/2/1
[Sysname-subscriber-line2/2/1] busytone-hookon delay-timer 3
calling-name
Use calling-name to configure the calling name for an FXS interface.
