[cisco-voip] Does anyone know the features sip phones do that have that SCCP phones can do?

Greg,
I'm actually a recent convert over to the feature parity of SIP <-> SCCP,  
especially in the UCM 7.0+ systems. Other than building each phone  
differently, in UCM, there won't be much loss. Now, using the cheap SIP  
phones instead of using the more feature rich devices like the 69XX or 79XX  
phones, that will come down to a cost / feature decision. I'd check out the  
69XX phones, it could save over $100k and keep you in the Cisco product  
line. It may come down to working with the local Cisco account team, get a  
demo of a few different phones, and run a pilot of about 10 or 20 folks.  
That way they know what features they will really want/need and see that  
they probably won't want those cheap SIP phones.
