Apologies for replying to my own post... it just struck me however that
Asterisk must be using the From header username from the initial invite to
generate the Proxy-Authorization "hashes" (nonce, etc) which it sends back
to the ATA.  The ATA uses these but populates the Proxy-Auth field with the
real username (not "Anonymous" which Asterisk is probably expecting) and
thus authentication fails because the two usernames are different.

Correct?
