  I'm a little confused here.  The caller will end up communicating
with the server for bfccomputing.com, which your SIP phone registers
with.  The server will then automatically transfer the call, in either
a supervised or unsupervised manner, which tells the caller to talk to
you directly at [unknown goes here, specifically, your IP address],
OR, depending on your configuration, call you directly and 'link' the
two seperate calls together.

  SIP can already do what you're talking about, without the server
needing to actually manage any sort of DNS records.
