Hangup call from manager(telnet) or CLI

Hello,

I would like to reject incoming ZAP call through Asterisk manager.
Problem is that call must be answered to be able to hangup it, as i understand.
If i use “soft hangup” CLI command or “ZapHangup” from manager it doesn’t terminate call since it doesn’t answer it.

SO i figured i need to pickup>play(busy)>hangup to terminate call.

But there isn’t any command to pickup or play audio from manager or CLI.

And it must be done through manager or CLI since it is sent from another computer in LAN.
Basicly I need to make “button” on that computer which allows me to reject incoming call on Trixbox machine.

How to do it?
