<p>The commit 81df84b is related to tls, so there should be no
relation with nat functions.</p>
<p>Are you using t_suspend()/t_continue() or other async processing
functions?</p>
<p>Anyhow, whatever changes you want to be specific for each
outgoing request must be done in a branch_route. request_route
changes are visible to all changes and if you do something again
in branch_route or failure_route, then you will see duplicated
operations.</p>

Since the upgrade to 4.4.4, when the original INVITE fails over to
voicemail (branch appended), fix_nated_sdp creates the SDP below,
doubling the replaced IP addresses. Asterisk replies with 488, as
the media address is completely invalid. I need something like
the above (which worked for the request and the reply) but can't
figure out what the problem is.
