Using a pots may not give an accurate picture. It is a source of echos which can, when combined with a slight latency introduced in the voip links, change an acceptable reverb to a nasty echo. The cheap clone cards are all of the x100 card I believe. It has a fixed impedance of 600 ohms pure resistive. A lot of countries outside USA seem to use other line impedances. The mismatch leads to echos. > For expandability, I believe that the cap I have seen is about 60 > concurrent calls for one Asterisk box and that is with a pretty serious > server by most users standards.

With no transcoding you should be able to go higher than that I expect. For local ip phones g.711 is probably usable. Most low numbers I have seen seemed to do a lot of transcoding to liwer bitrate formats.
