Physical Button to Play Message

[PilotCaptainMorgan]

Is there a way to use a normally open button to dial a code? I have a button that can lock a door if needed and I would like for it to trigger a page to come over the PA. I have figured out how to make a page via voicemail pro and a short code (thanks to this forum) but I can not find any kind of interface that would let me dial a short code from a contact closure. The only way I can think of it is to take a phone apart and solder the button to a programable button on the phone.

Ring down analog phone set to dial the shortcode. When you make the contact the system sees it as a off hook and dials the shortcode. I used to use it for time tones for school class changes.
