[OpenSIPS-Users] UDP vs TCP/TLS

[leo]

Thanks Razvan.
I'm still trying to troubleshoot this problem, i've seen that in the opensips logs, when i place a call, there are the following error messeges:

I didn't reply before because i was serching in the forum but i didn'n find any helpfull topic.
Do you still think that is a network issue? Do those error logs have a meaning?
If you see, form the call placing to the incoming replay there are 10 secs.

Thanks a lot,

Leo.

Hi, Leo! 

This doesn't seem to be related to OpenSIPS. My suggestion is to trace 
this at the network layer and check if and why the TCP/TLS connection is 
taking 15-20 seconds.
