I guess if you're leaving the forum I don't need to respond, but I will because I think your post is very confusing.
If you want to port your number to Google Voice, you can do that. CCF doesn't come into the discussion.
If you want to KEEP a cell number but have GV provide the voicemail capability, then CCF forwards the call to GV should you not answer it. Apparently TracFone doesn't support this, so therefore, if you have TracFone as your cell provide AND WANT TO KEEP IT, but you WANT TO USE GV FOR YOUR VOICEMAIL, you can't.
