A standard desk phone like those associated with a phone system or just a plain old house phone? Additionally, when you say analog channels, do these consist of dial tones? I noticed when I placed a call, there were no dial tones. I simply dialed and it rang. I'm googling now looking for a manual.

Thank You so very much,
All of you are such great advice and tip givers
I will continue to play with this. Additionally, I will also keep my eyes glued on this forum for new postings.
