Configuring busy tone detection

This section describes how to configure busy tone detection for FXO voice subscriber lines.
Configuring busy tone detection parameters for the FXO voice subscriber line
The actual specifications of busy tones might differ from the configured parameters. If this is the case,
busy tones cannot be recognized, resulting in failed or false on-hook.
To configure the busy tone detection parameters for the FXO voice subscriber line:
Step
1. Enter system view.
2. Enter voice view.
3. Configure busy tone
detection parameters.
4. Configure the type of busy
tone.
5. Quit voice view.
6. Enter FXO voice subscriber
line view.
7. Configure the number of
busy tone periods for
detection.

You can increase the number of
busy tone detection periods by
using the busytone-t-th
command to improve the busy
tone detection accuracy. This
reduces the likelihood of false
on-hook, but increases the
likelihood of failed on-hook.
