What is Digital Phone?
VoIP is the transmission of voice over packet-switched networks.

Traditional voice networks utilize circuit-switching technologies. Effectively, a pair of copper wires is used to connect one party to the other, completing an electrical "circuit". With packet-switching, traditionally used by IP based networks such as the internet to transmit data, voice signals are broken down into tiny "packets" of digital sampled data, sent and then reassembled at the receiving end. The efficiency in voice over IP is in part down to this packet process. Multiple conversations (as many as 6,000) can be transmitted over one pair of copper wires.

Wider adoption of VoIP has been largely down to advances in IP networking technology, and processor speed increases. The faster a processor can sample voice data into small packets, and the faster those packets can be sent over an IP network, the better and more efficient VoIP becomes.

Plus, you get all the benefits of Landline Phone service, which include unlimited local, in-state and long distance calling throughout the United States and Canada – all for one simple monthly price as low as $24.99.


What if I don't have a dial tone?

  1. Check all the phones in your home for dial tone. Make sure that none are off the hook.
  2. If the lights are off on your modem, make sure it is plugged into a working power outlet. If it is plugged into a grounded outlet (3-prong with black and red buttons), make sure the red reset button is depressed. Check your circuit box to make sure none of the breakers are tripped. Make sure the power cord is snugly plugged into the modem and outlet.
  3. If the lights are on, but there is no dial tone, plug a phone directly into the back of the modem to see if you can get a dial tone. If you are able to get a dial tone this way, please Contact Us Verify that the telephone line plugged into the modem is in the "telephone 1" or "telephone 1/2" port.
  4. After selecting desired rental from category selection, select “Buy Movie”
  5. If you are still unable to get a dial tone, please Contact Us on your cell phone or other available phone
