I've been using the Voice Logic Pro 206 (the 6 port box) without major problems. Though the original instructions were faulty I played around with numbers, codes/keys til most things worked.

However, I can't utilize Call Waiting. I have the feature through my phone company but the Voice Logic directions don't work when I try to flash over. Can anyone help?

I have the American Business Communications instruction addendum, the twacomm.com brochure/manual, etc.

Please respond or message me. Thanks in advance for yor help.
