What is an IP Phone?
An IP Phone is any phone that uses the IP (Internet Protocol) to make and receive calls. Commonly referred to as VoIP Phones (Voice over IP phones), IP phones make and receive calls via the Internet (or Intranet).
IP phones are considerably more affordable than older non-IP enabled devices. As such, they offer a far greater level of flexibility and scalability when it comes to a business communications solution, compared to the traditional wired PSTN phones which required labour intensive setup and therefore a significantly higher cost for a much lower feature set.
Basically any standard desktop phones (an ATA adapter may be required), smartphone and tablet devices, and softphone apps can all be used to as a VoIP phone.
