I can't thank you all enough. I'm making a ton of progress. I've got my system doing "something" like it should. My issue now is the Lingo is picking up ALL incoming calls, even though I have set it to Application # 3 VM only, no automated attendant.

p.s. I was also able to obtain a complete set of Lingo manuals via email from Active Voice. If anyone could use these, I'd be glad to forward.
