What is the difference between an IP phone, ATA and a PBX?
An IP phone is a phone very similar to your normal PSTN phone. The only difference is that normal phones connect to RJ11 wires coming from your Wall socket where as an IP phone connects to your Data cable RJ45 which might be coming from your Switch which in turn is connected to your home DSL or Broadband router. An IP phone comes with standard buttons and functions that you normally expect in your usual home phone. IP phones are commonly used in business because in business every staff usually has a phone next to them with all necessary functions such as Voicemail, Transfer, Conference etc. where as at home we don’t expect to be using these functions. Usually we don’t get as many different models, functions or types of IP phones like standard phones. Home users are now purchasing IP Phones and are taking advantage of all these features, particularly the homes users who also have a home office.
