Thanks Steve. It's been quite a while since I've even seen a Comdial 308--and I had forgotten about any analog adapter that would work with them. I don't even know if they are functional as far as transfers go. I'm putting in a T/R Connector on a AT&T Spirit next week..and notice in the documentation that transfer capability does not seem to be there for that unit. Some of these earlier analog adapters had some real limitations as to what they could do.
