A Vo IP phone or IP phone uses voice over IP technologies for placing and transmitting telephone calls over an IP network, such as the Internet, instead of the traditional public switched telephone network (PSTN).
According to this view, the smartphone becomes the dominant Vo IP phone because it works both indoors and outdoors and shifts base stations/protocols easily to trade off access costs and call clarity and other factors personal to the user, and the Po E/USB Vo IP phone is thus the transitional device.
The components of a Vo IP telephone consist of the hardware and software components.
The software requires standard networking components such as a TCP/IP network stack, client implementation for DHCP, and the Domain Name System (DNS).
In addition, a Vo IP signalling protocol stack, such as for the Session Initiation Protocol (SIP), H.323, Skinny Call Control Protocol (Cisco), and Skype, is needed.
For media streams, the Real-time Transport Protocol (RTP) is used in most Vo IP systems.
