asterisk users - Jun 2007 - Verizon Interconnection

Hi,
Has anyone on this list connected with Verizon's SIP product?  We are
currently undergoing interop testing with Verizon, and honestly, it seems
like the most convoluted process.   I'd be interested in talking with
someone else who has gone through this and run a few things past you.

So absolutely no one here was interconnected with Verizon?  I am going to
shoot this over to asterisk-biz, also, in hopes someone may have missed it
that is on the biz list.  The question again is:

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.
