QOS

Maybe QOS first to put off that "you ain't in Kansas anymore Toto" feeling you'll get when you hit the voice stuff.
CVOICE is also an option for "first" -- since it's the intro to voice and is still "router-centric." It would be less of a shock coming from the CCNA, and might be easier than the QOS exam (without the CCNP).
Which leaves CIPT and GWGK...... CIPT is the CallManager exam, so you'll hit some gateway/gatekeeper configuration stuff here -- so its probably a good warm up for the GWGK exam.
Over in the CCVP Books thread I said QOS, CVOICE, CIPT, GWGK and IPTT is the sequence I finally did.
I found IPTT to be the easiest of the voice exams.... but that's probably because of all the study and practice for all the other exams.
