Has anybody seen an IP version of the PGD (or equivalent)? What does everybody else do with external paging in locations where there is no copper cabling back to the system?

Customer has the SV9100 in their main office and at their second building, that is fed via a point to point wireless system, they are using all IP phones. What we have done in the past is place a phone near the amplifier and connect off the internal speakers to the amplifier input. It works but is a waste of a phone.

Anybody find anything that works well?
