Not at all. There are two ways to go about doing this depending on your home or office network setup. It takes only a few minutes to be up and running making and receiving calls.

1) If you have or will have your own router, you simply connect the analog telephone adapter (ATA) that we will send you to your router in an open port and then connect an existing phone to your adapter.

2) If you request an ATA with a router built in, then you will simply connect your ATA/Router to your DSL/cable modem and then connect an existing phone to your ATA. Your other network devices will then connect to your ATA/Router via available open ports.

After doing either 1) or 2), then plug your adapter into a power socket and you're ready to go! You should have a dial tone in about 3 seconds.
