The default port for our private Trixbox VOIP systems is 5060.  If this port is blocked by your ISP or internet provider, you can change it within the TrixBox interface under the “PBX Settings” page.  Once on this page, you will want to edit an existing extension or create a new one.  Under “Device Options”, you should change the “port” field.  Make sure that you also setup this same port on whichever device you are using to connect up with the TrixBox.  Make sure that you do not use ports that could conflict with other programs that you are running on your computer (25, 80, 110, 443).

This enables you to change your VOIP SIP port from 5060 to port 80, etc without using a VOIP Tunneling Tool.  Sign up for a private VOIP system with a dedicated IP that you can admin, and change the default Ports/Passwords on today.
