Hi List
I have a problem with OpenSER. OpenSER has a public IP and is not behind a
NAT. Two clients that are behind a NAT ring each other but there is no
audio either way. Any advise please?
Sencond scenario two clients both behind the same NAT. . Client1 calls the
Client2, Client2 UA rings, Client2 answers the call but it does not
connect. Client1 call does not get answered by Client2 and Client1 just
hears the ringing tone. Any ideas?
Best Regards

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

Hi Guys
Thanks for the advise. I have the clients using a public stun that I know
works but no audio. I have tried the mediaproxy route but having trouble
getting the proxy to start. I will look into the rtpproxy method.
Many thanks
Craig
