md5 instead of plaintext?

Also, I think I just seen a change in the last day or two that had
something to do with 403's, and if I recall correctly, it also addressed
upper/lower case something or another.

Can you use ethereal or sip debug to determine the exact item that was
sent that might be causing the 403? Either one should at least provide
a hint.
