Excellent Phone Tech Support Bulletin Board

I have searched a couple of times over the last few years for a discussion forum or other online help for supporting our Executone phone system. We've been doing self-support for about 3 years, and can handle most of the basics no problem. But those weird/rare problems pop up we're at the mercy of hourly support to handle it. A lot of these are easy fixes, if you've seen them before. At $100/hr, 2 hr minimum, and a $100 trip charge - it's at lease $300 to have someone come out and do something stupid like scrape oxidation off the motherboard battery... So the online discussion forum from Sundance Communications is like finding a pot of gold. Thanks to them for being cool enough to bring these forums public and break the secret fellowship of phone service techs that seems to exist!
