An Internet service provider (ISP) may impose restrictions on its customers by blocking access to certain websites or filtering ports, which are used by various types of applications to communicate with your operating system server to server. If your ISP blocks a VoIP port, you'll be unable to use VoIP services on your computer. In this case you can get around the ISP's VoIP port block by using a virtual private network (VPN) that gives you access to VoIP and any other blocked ports through its server.
