[OpenSIPS-Users] UDP vs TCP/TLS

[Răzvan Crainea]

Hi, Leo!

 From the logs, for me it is pretty clear that the connection does not 
exist, therefore OpenSIPS cannot contact your client behind NAT.
After finally managing to call over TCP (after 10 seconds or so), 
placing another call succeeds? Or you can never call that client over TCP?

Best regards,
