Cisco's SIP features on the phones are getting close to parity
to skinny, but I get the feeling that the price is still using
CCM.  I believe that the 7921 has a SIP firmware in the works,
and that the 793[56] phone firmware is actually produced by
Polycom.

Oh, and the new XXX1 phones are supposed to be running a 
Java OS, so yes the registration format is likely to be
very different....

I think the channel is coming along nicely.  Factor in how
miserable it can be to get a license to download SIP firmware
for used phones, and the channel becomes more appealing.
