Hello,
you have to use a nat traversal solution. If the clients are behind
symmetric nat, then you have to use server side components. OpenSER has
two server-side solutions for nat traversal:
- nathelper module + rtpproxy
- mediaproxy module + mediaproxy
If the clients are not behind a symmetric nat and they support STUN,
then you can let them to deal with nat traversal, you just need a stun
server (there are some public STUN servers available for use).
Cheers,
Daniel
