Media flows not properly set up in Re-invite.
No video/audio can be passed during the specified condition.
Using TCP, set up a hairpin call. Do a re-invite from the client that did not initiate the call, and it will be noticed that the media flows are not set up with the proper SNAT IP (they seem to be reversed). If the re-invite is initiated from the same client, the problem does not exist.
Call from clientA is hairpinned by the BIG-IP system, a reinvite is sent from clientB, the media flows are properly set up.
