VDI is a great one from ECS in Ventura, CA. You need the analog call-in to use the C-phone or VDI station (C-phone sounds best). Do not get the sound file model. You will also need a dedicated phone line or 2. You can purchase a skutch station to wire directly into your call-in system without requiring another phone line to access the dictation. If you just have one doctor or a few, I have a call-in system that uses voice files and is easy to set up that I am considering selling. My accounts went EMR. My e-mail is diannalazan@yahoo.com if you have further questions.
