Currently I have a Cisco E4200 Router with 4 Ethernet Ports. One is being used for a Magic Jack phone line and we would like a second phone connected to an Ethernet port but all ports are in use. What is the simplest way to enhance this router without having to buy a new one with 5 Ethernet ports?

Buy a switch. Add another 4 ports for $20-$35 from Amazon.
Just buy a small switch (see below) and connect to one of your router ports.
