[AFMUG] SIP paging adapter

[Ken Hohhof]

Has anybody used a SIP device that drives paging speakers?  I started out 
thinking of an ATA plus a Bogen TAMB2, but I see some SIP devices that look 
better featurewise.

From spec sheets, I'm liking the Cyberdata 011233 or 011061, but the Valcom 
VIP-801A is cheaper.
Any recommendations?
