<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This seems like a fairly intrusive change for a release branch. If we're going to make this change, then the SDP_offer_answer test should be passing with no modifications to the test.
If its failing because Asterisk no longer rejects offers in the same fashion, then I'm not sure we should make this change in a release branch.</pre>
