I was under the impression that the Cisco fixup protocols broke the SIP headers
Long time ago this was a problem. But I know of a customer which uses an Asterisk behind PIX and it works fine.

HI PAtrick!
Cisco PIX will usually rewrite SIP messages (ALG) thus it should work.

Is is possible to have a SIP UA behind nat and communicate to an OpenSER/RTP Proxy server behind nat behind nat and have everything transverse appropriately? Or will I need something additional like STUN?
Example:
OpenSER + RTP Proxy + Asterisk will all reside on the same machine.
SIP UA -> Cisco PIX ( Public IP to Localnet NAT ) -> OpenSER/RTP -> Asterisk
Thank you for your time,
