I have some updated information that may be useful for some of you. "Apparently" 2.66 also has the same issue's as 2.69's unauthorized conference calling. BUT, "Apparently" 2.66 only works properly with the T1 in the first slot of the 500's. If you have multiple T1's ...expect the unauthorized conferencing issue's.

Anyone receive any "Announcements" or "Product Bulletins" about this?

Please PM me if you have to.
