Configuring an on-hook delay
An FXO interface goes on-hook when detecting a busy tone. This will cause the user of an 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 solve this problem, you can configure a delay time. During the delay time, the FXO interface continues sending the busy tones to the IP phone.
To configure an on-hook delay:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter FXO interface view. | subscriber-line line-number | N/A |
3. Set the delay time from when the FXO interface detects a busy tone to when the interface goes on-hook. | busytone-hookon delay-timer value | The delay time is 0 seconds (the FXO interface goes on-hook immediately after detecting a busy tone). |
