[cisco-voip] Integration into Fire System

[Wes Sisk]

"detecting voice" is non-trivial.  You will need to find a reliable way 
of triggering a 'start event'.

With that trigger you can likely use the "MOH live feed from CME/SRST 
router E&M port" trick to get the audio from the fire system into a 
multicast stream. After that you just need to get the phones to listen 
on the multicast address.  Talk to your paging vendor to see if they can 
allow you to specify a specific stream address. It is certainly possible 
to tell the phones to listen to multicast stream, your paging system 
uses it today.

All of this still depends on finding a reliable trigger event.  
'Detecting audio' is not simple or reliable.
