VoIP PBX (trixbox) to Overhead Paging

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?

Any thoughts or recommendations are appreciated?

Thanks in advance!

FXS port to an analog paging system (like Viking) is going to be more reliable.

We built page/ring groups with Polycom phones using Switchvox.  It is very messy.
Each SIP phone has it's own way of handling pages.  Even different models among the Polycom work differently, so our paging invariably leaves several phones off-hook.

There are VoIP-enabled paging speakers, but they run >$300/unit.  For a warehouse, just use the existing infrastructure.

Think of your VoIP PBX as just another PBX.  Use the appropriate tools for the job.  Not the fancy ones.

So is an analog system like Viking the way to go?  Is Viking a good one to be looking at?

Viking has been making door controllers, paging, apartment access (call boards) for years.  I use and trust their equipment.

To be truthful, I have not used their paging interfaces.  But, I've trusted their access control hardware with my own personal safety at multiple locations.


You can find a lot of paging equipment here: (good supplier, BTW)
