Unless you have some firewall rules on your computer/router that would cause this, the most likely culprit is a router with SIP ALG support. These routers claim to better support SIP, but all they do is break it. I have yet to see a single router that properly supports SIP. Thus, I recommend to check your router and if it has SIP support and disable it. The sip2sip platform is able to properly support NAT traversal without the help of any router.

If you do not have access to your router, you can always try to enforce using TLS, which routers will not mess with. For that go to the account preferences in the Server Settings section and set your outbound proxy to proxy.sipthor.net port 443 TLS
