I have a similar setup where I work. I used a Viking PI-1 unit connected 
to the amp and a SPA-3000 connected to the viking. This gave me overhead 
paging and ringing. It did require a little tweaking on the SPA side 
because the PI-1 only provides 12V instead of the normal 48V to CO port. 
It's been working fine since it was put in about 8 months ago. I think 
the Viking unit was about $120. More info in it here:
