One of my clients is using the Redfone TMDoE devices with excellent 
results.  The installation has been in place for over a year.  To (try 
to) answer your specific questions:

Takes up to 4 PRIs.

Haven't faced any echo issues so far with up to 400 simultaneous calls 
on a single box, load balanced over multiple Redfone/PSTN gateways.

You could get pricing from them.

Fairly straightforward.  The scripts supplied by Redfone work for a 
single device connected to a computer.  We're connecting up to 6 devices 
(6 x 4 x 30 = 720 lines), and have made our own set of scripts to handle 
that.

As far as I know my client's blood pressure has remained stable over the 
non-Redfone <=> Redfone transition :)
