<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This test loops through all combinations of nat=route/no (force_rport/no in 1.8+) for [general] and [peer] in sip.conf, whether or not the incoming request specified ;rport in the Via, and whether request was sent from the same port as the one listed in the Via, for both a valid and an invalid user. The test records when the behavior differs and matches against when we expect that behavior to differ for each version of Asterisk (1.4, 1.6.2, 1.8, 10, trunk). It also uses a Quine-McClusky minimization solver to reduce the list of failures to a function describing the failures. For example:
On 1.4:
(((NOT port_matches_via) AND peer_nat AND (NOT general_nat)) OR ((NOT port_matches_via) AND (NOT peer_nat) AND general_nat))
and 1.8:
(((NOT port_matches_via) AND (NOT rport_specified) AND (NOT peer_nat) AND general_nat) OR ((NOT port_matches_via) AND (NOT rport_specified) AND peer_nat AND (NOT general_nat)))
As you see, there is an extra term in 1.8 because in 1.8 we honor the ;rport in the Via no matter what, so differing behavior only occurs when a request comes in *not* specifying ;rport. There is no equivalent for nat=route or nat=never in 1.8+ (these values were originally added to work around a bug in old Uniden phone firmware).
This patch also adds a very small SyncAMI class for synchronously sending AMI requests (over HTTP because it is much simpler to do via HTTP's built-in request/response architecture) and getting back a response. It also modifies the default manager.conf and http.conf files to support the new API. SyncAMI makes it much easier to do things like update a config and reload it over AMI as you don't have to split up what you are doing into a lot of callback functions and you really do want to block execution until they are complete. Normally, I would have done a separate review for SyncAMI, but as this patch requires its use I've left them together for the review.</pre>

The nat options for 1.4 and 1.6.2; and 1.8, 10, and trunk are the same, so I expect similar behavior there.</pre>
