I have been told I can record a coversation into a mailbox by pressing a one touch button on my handset, I have TDA200 with TVP100, I have adjusted Class of service and programed the button, but when I press the button on the phone while talking it does nothing.

when you say adjusted class of service did you mean on the tda or tva?

Thank you, MrG

Do you have your 2-way rec button pointing to your voicemail ext'n?

I found the problem, for some reason their is a delay from when you press the button on your handset untill the actual light on the handset comes on/starts recording. I guess its a delay getting into the voicemail system. Another annoying thing is that you cant record a coversation whilst you are monitering someone else's conversation.......

HI Capt. Canwrench
I had it pointed to the pilot number of the voicemail !
