configured) ring tones, a dial tone is played. At this time, users can dial a VoIP telephone

number is entered after the dial tone, Unicorn 3112 will hang up automatically in 10
seconds.
In the web configuration page, if the Route to VoIP field is configured, the second stage
dialing is eliminated. That is, after users dial the FXO port telephone number, the VoIP
