[OpenSIPS-Users] 408 Request Timeout with UDP

[Nabeel]

My OpenSIPS runs on a public IP.  The callee was connected to Wi-Fi in my
first test earlier, but in the second test the callee was connected to a
public IP  (public mobile network).  In both cases, the same '404 timeout'
error occurred on call attempt.  The SIP trace for the second case is at
this link:

Regarding private IP, you said it's impossible to route from public IP to
private IP.  Although at the IP level this may be true, even if the user is
on Wi-Fi, the whole point of NAT traversal is that the user's public IP is
discovered and the call can get connected, is that not right?  I'm fact,
using a TURN server and a different SIP proxy, I was able to connect these
same devices under the same networks, so I know this should be possible.  I
feel something is not configured correctly in OpenSIPS / rtpproxy.

I did "opensipsctl ul show" and the results seem normal; please check it:

Perhaps the NAT processing just needs a bit more time; in thar case what
are the config options to increase the request timeout for UDP?  I have
seen the 'tcp_send_timeout' and 'tcp_connect_timeout' options for TCP, but
please let me know if there are similar options for UDP.
