I have a client that I'm bidding out a trixbox VoIP phone system for. They have an office with an attached warehouse. They want to be able to page the warehouse. What are the best ways to do this with a VoIP PBX like Asterisk?
I know you can do FXS port to a paging system (like Viking). What about VoIP options? Can you do a phone with auto answer and hook it up to an external speaker system?
