Features include: auto answer/originate, audio input to phone network, DTMF or pulse dialing, dial tone and call progress tone detection, password/dialback security, etc, etc. Unfortunately, there's no speech synthesizer, but you can connect one to the audio input port. You should be able to get info from the sales reps mentioned, or you can call us directly. --- Kirk Bellar KE7TN Teltone Corp. (Tones `R' Us) uw-beaver!tikal!kirk Kirkland, Wa.
