Going back to my original question then, under the premise that fixup
is disabled, should this scenario work correctly....<br>
<br>
Is is possible to have a SIP UA behind nat and communicate to an
OpenSER/RTP Proxy server behind a different nat and have everything
transverse appropriately? Or will I need something additional like
STUN?<br>
<br>
Example:
<br>
<br>
OpenSER / RTP Proxy / Asterisk will all reside on the same machine.
<br>
<br>
SIP UA -> Cisco PIX ( Public IP to Localnet NAT ) -> OpenSER/RTP
-> Asterisk
<br>

My experience is the same, with all ALGs. For some reason whenever an
ALG tries to 'fix' the headers, they end up fixing it the wrong way,
thus breaking things even more.
