I came across this site while trying to find someone that could help with my problem. I work for a K-12 school in Cincinnati. Six years ago we constructed a new building and had someone install a Valcom paging system. This was one of those (side jobs) by a cabling guy. Apparently he didn't know what he was doing because it has never worked properly. Every time it rains, the system does not work. It doesn't perform the "all call" function and any announcements made are filled with static. I have had a few companies come in and none have been able to identify the problem. I don't know what to do. We rely heavily on that system. Do any of you know of anyone in the greater Cincinnati area that knows how to work on a Valcom system? We do not have anyone on staff that understands the system. HELP!
