Andreas' analysis is on the mark. BTW, CCP means "Compression Control
Protocol" and negotiates the software compression options for the link.
The protocol failures are pretty typical when connecting a Linux box to an
NT box that has all protocols enabled for PPP. I presume you don't care
about x802b (IPX) or x8029 (I can never remember this one), so ignore
these messages.

I agree. It looks to me like you might be telling the ISP which IP
address to use (207.250.150.149). Do you have a line that specifies IP
addresses in your options (e.g., 0.0.0.0:207:250.150.149)? If so, remove
it and use only 'noipdefault'. You could also use 'ipcp-accept-local' and
'ipcp-accept-remote', which overrides any option-specified addresses with
ISP-provided addresses.
