Which SIP product.  I know of at least two SIP products that Verizon
offers (2-way traffic and Carrier IP Termination), and there are
probably more.  I helped a client of mine go through the interop
testing on both of the products listed above.  I also know that a
friend of mine has done the same thing.

Yes, it's very in-depth testing, which isn't a bad thing to do with
your upstream carrier.  If you understand SIP and Asterisk, it isn't
terribly difficult to do.  Mostly you just need to make sure you
understand what they want in the P-Assert-Identity header and make
sure your phone numbers are formatted correctly (sometimes E.164,
other times not).

What specific questions did you have?  I can't guarantee I remember
the answers, but go ahead and throw out the questions.
