   Connect the handset to the base station. If the handset has a cord, connect it to a RJ-11 phone jack on the base station. If it is a cordless phone, place the handset in the base station and let it charge. If the handset requires batteries, put the batteries in the handset.

   Connect an Ethernet cable to the base station. Look for the Ethernet port on the base station of your phone and connect the Ethernet cable that came with your phone to the port. Some VoIP phones offer an Ethernet pass-through option. This allows you to connect another device, such as a computer, to your phone so that you only need to use one port on your router to connect two devices. If you wish to use this option, connect your computer's Ethernet cable to the port on the base station that says "PC" or something similar. Connect the Ethernet cable that came with your phone to the port that says "SW", "switch", "Internet" or something similar.^[1]

   Connect the Ethernet cable to the router or modem. Most routers and modems have 4 numbered Ethernet ports on the back. Plug the Ethernet cable to any one of the ports on the back of the router. Look for a message that says "Initializing network" or something similar on the screen.

   Power up the modem and router. If you have a separate modem and router, plug in the modem first and wait 30 seconds for it to resync with the network. Then plug in the router and wait 30 seconds.

7. 7

   Plug in the base station of the phone and power it on. Place the handset in the base station and plug the base station in. If needed, allow the handset battery to charge for a while. Power on the phone and wait 30 seconds.

8. 8

   Check for a dial tone. When you see the screen turn to the standard home screen, pick up the phone and check for a dial tone.

   Check your router's capabilities. Some router's, such as the TP-Link AC 1900, have built in DECT capabilities. This allows you to connect the handset of a VoIP phone directly to your router. Check your router's capabilities in the user's manual. When you purchase a VoIP phone, check the box to see if it supports CAT-iq or DECT capable routers.

2. 2

   Charge or put batteries in the handset. If the handset uses AAA batteries, put a fresh set in the handset. If the handset uses the base station to charge itself, connect the base station to the AC adapter, plug it in, and place the handset in the base station. Let the handset sit for a while so that batteries can charge.
