<br>
If you are using something below TLSv1 you might as well just turn it off<br>

<br>
I&#39;ve upgraded my FS from 1.2 to 1.4.14 without changes in the config files and TLS stopped working. I can&#39;t register any more (503 service unavailable error).<br>
I don&#39;t see any logs in the console, but with ngrep I can see that the traffic hits the server on port 5061.<br>
tls_version =  sslv23<br>
if I change to tlsv1 I can register but outgoing calls don&#39;t work<br>
Any ideas?<br>
