At one customer site I use a linksys ATA setup with auto answer,
connect the tip and ring of the FXS port to the audio input of the
overhead paging system, works fine.  Also at another customer site,
the paging guys installed a audio input device that activates when
ring voltage hits the line, http://www.valcom.com/v-9970.htm .
Installed an ATA, nothing special, call that extension and device
brings the ATA off-hook then bam, your passing audio to the paging
system.  You can pick these up for ~$200.

The phones you are using might support it already (and not even need  
the system)

the grandstreams I have do, but I can't speak for any others.
