>From what i see (at least in the UK), it seems to depend on if the
provider is selling "PSTN termination" or "SIP services".  The former
tend to place many restrictions (make calls only if registered and
from the IP that registered, only allow a single binding in AOR, etc),
and the later tend not to (although may provide customers with the
ability to).  In the UK, I'm seeing a slow shift from the former to
the later, although no idea about the rest of the world.

hmm, the above paragraph could almost have been talking about
AOL/compuserv vs a "real" ISP 15 years ago :-)
