I don't know about that, the Grandstream phones support 8 different 
codecs, the old chinese PA168-based phones supported 6, as do the newer 
AR1688-based handsets, the linksys SPA922 has 4, the SPA962 has 5, the 
old Snom 300 has 7 (including G.711).

The IP501 has 3. I know it's a considerably better handset than say the 
PA168 or AR1688-based handsets, but then they are $45 and the 501 is £125.

I'd also be more sold on it if it had half the features of the GXP2000 
(which is only a little over half the price).
