I have a fair amount of telecom experience, although I'm a little rusty on some points. I'm still not sure why the Debut won't answer. I believe anything that is plugged into its ports (CO line or ATI-D)actually has the effect of taking Debut off-hook, hence the busy tone when I try to dial in. However, when I monitor the port with a butt set I don't hear any greeting, etc. I don't think I need Keylink at this point unless it would help me "re-boot" Debut? Thoughts?
