Here is the situation : SIP phones are in a private LAN A. They can speak with the server hosting openser and mediaproxy which is located on private LAN B. This server can speak with the internet through a router that nat (1:1) its private IP on a public one.
To be able to interconnect inside sip phone with outside ones, openser must advertise the private address of the mediaproxy to the inside sip phones and its public (nated) address to the outside sip phones. But afaik , the media proxy module doesn't let me dynamically choose the IP which replace the phone IP in the SDP.
How do you think I can get through this ?

AFAIK rtpproxy supports this. Thus, at worst case change to rtpproxy.

An idea that I've adopted, which may not work for you so its only a suggestion, is use OpenVPN. That is run your OpenSer as a OpenVPN server as well. OpenVPN is fairly easy to setup and it overcomes the NAT issue, that is you simply let the one OpenVPN port thru and all the devices internal or external can be attached to the OpenSER server as either host-to-server or network-to-network peers. It works so well I'm making softphone client calls thru my OpenSER bounced to my Astwrisk PBX and on through to any legacy analog PSTN phoneline telephone. Just an idea that works for me
