The 5330 IP phone by Mitel uses voice-over-IP (VoIP) technology to place and receive phone calls. The calls are placed over an Internet connection rather than the ordinary public switched telephone network technology used by land lines. Phones can be configured to work off the Internet or a private IP network within a company. The 5330 is an enterprise phone designed as a cost-effective solution to work over a company's private IP network. The static IP of the company's network is needed to allow the phone to work on the network.
