Paging Device Limitations

I want to revisit the 25 phone paging device limitation. Is there any creative workaround to extend this limit?

The issue with network traffic is, to me, nonsense on an enterprise-level gigabit network, particularly in a health care facility where a medical code incident must be broadcast to various offices that will never contain paging speakers.

FWIW our previous Cisco UCS system implemented Informacast which could page 250+ phones and our network somehow survived the onslaught every time I tested it. ;-)
