When I was at PacBell around 1998 we were deploying VoIP using the
3801's and it wasn't uncommon to use Frame Relay on a standard serial
line so that Frame Relay Traffic Shaping could be configured to help
ensure voice quality.

I actually did use back to back FR once, as I needed to fragment on a
slow circuit to maintain decent VoIP quality. But it's pretty rare to
have to do so.

I suppose the back to back frame is more or less of frame relay without
a real frame relay infrastructure?
Clearly, not a real life need. Why deal with frame when you can just
run HDLC or PPP accross straight circuit? :)
