Playing a sound through our SIP Valcom loud speakers when a door is opened.
We have an Asterisk FreePBX phone system with a few Valcom IP bullhorns in our warehouse. We would like to set something up that when the door to the warehouse is opened, a sound is played through the bullhorns to notify the workers in the warehouse that someone has walked in. The sound could be a ding, buzz, etc. it doesn't really matter. What equipment do I need to be able to do this?
