(Internet Protocol phone) A telephone that is used with voice over IP (VoIP) telephone services. The IP phone plugs directly into the Internet and converts voice into IP packets and vice versa. It has built-in SIP signaling and is used in conjunction with an IP PBX in an enterprise or a hosted VoIP service. An IP phone can also be software installed on the user’s PC for calls made at the computer. See VoIP, hosted VoIP, and IP telephony.
A VoIP phone or IP phone uses voice over IP technologies for placing and transmitting telephone calls over an IP network, such as the Internet. This is in contrast to a standard phone which uses the traditional public switched telephone network (PSTN).
Digital IP-based telephone service uses control protocols such as the Session Initiation Protocol (SIP), Skinny Client Control Protocol (SCCP) or various other proprietary protocols.
A VoIP (Voice over Internet Protocol) phone is any phone that makes voice calls via an Internet connection instead of via the traditional wired telephone network.
Standard desktop phones (also called hardphones), mobile devices, and softphone applications can all be used to make/receive VoIP calls.
These VoIP phones bring far more flexibility, scalability, and affordability to business communications, especially when compared to the intensive setup process, high costs, and limited features of the copper-wired PSTN (Public Switched Telephone Network.)
