Ports are closed and I want to connect to SIP

Posted:Tue 13 of Sep, 2011 (14:26 UTC)
Hello everyone.
Some ports are closed on my internet connection.
I even connect to messenger through port 80 or 443. every time I try to connect, it fails because of no respond. But when I try to connect using openvpn it connects.
Please help me find a way to connect to a VOIP client. and by the way my operation system is Mac OS.
Thanks guys.
