How do I connect my Grandstream ATA box?

Out of the box

Your Grandstream Analogue Telephone Adapter or ATA comes pre-configured and ready to go. In the box you'll find:

  1. Grandstream black box
  2. Power adapter
  3. Lift the insert out of the box to find the Ethernet cable

Plug it all in

Here's a quick look. The router is on the left, Grandstream ATA in the middle, and obviously, a telephone on the right. Notice the ATA sits between the router and the telephone? The telephone plugs into the Grandstream box via the telephone's phone cord and the ATA is connected to the router via the included Ethernet cable.

Notice the phone is plugged into the green socket on the Grandstream and the router is plugged into the blue socket?

The back of the Grandstream ATA box

As mentioned before, the blue port is for the Ethernet cable to connect the ATA to a data port (yellow) on the router. Clearly, the home phone is plugged into the green port. The great thing is you can't mix this up because the Ethernet port and the telephone port are different sizes so only accept one or the other.

Connecting to the router

The final step for geting your phone working like a landline. Choose any Ethernet port on the back of the router to plucg the ATA into. In this diagram we've used Port 1.

(Notice the power cord is missing from the router, on purpose)

All done!

So with the ATA turned on for around a minute to give it time to boot up and connect, once you lift your handset you should hear a dial tone just like normal.
