Reserving a busy line (Automatic Callback Busy)
You can set the telephone to receive callback ringing when a dialled line becomes idle. When you answer the callback ringing, the called party starts ringing automatically.
If you hear a busy tone before dialling, you just seize an outside line after hearing the callback ringing. You can have two methods to answer according to the setting conditions.
