Duress Button 1

[FrankGrimes]

I have a Mitel 3300 running software version 5.
I want to setup a duress button for the front reception person. She has a mitel 5324 handset with a 48pkm. I was thinking of using a button on the pkm that the person could press and the word "Duress" would show up on a few of the phones in the back.
I have created a ring group and named it duress but I want to stop the ringing when she hits the button.
Any ideas?

I was thinking of using one of these Link but I just wanted to know if someone has done it an easier way.

Use an Analogue Extension and hotline it a Multicall. when the analog is looped ie a switch or push pull button, the phones ring that multicall.
