Voice over Internet Protocol (Voice over IP, VoIP and IP telephony) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet.

The terms Internet telephony, broadband telephony, and broadband phone service specifically refer to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN).

X-Lite is a proprietary freeware VoIP soft phone that uses the Session Initiation Protocol.

In September 2010, the Vancouver based CounterPath Corporation released X-Lite 4.0, which incorporates many of the features from X-Lite 3.0 but has a redesigned user interface based on CounterPath's Bria softphone.

Unified communications (UC) is a marketing buzzword describing the integration of real-time enterprise communication services such as instant messaging (chat), presence information, voice (including IP telephony), mobility features (including extension mobility and single number reach), audio, web & video conferencing, fixed-mobile convergence (FMC), desktop sharing, data sharing (including web connected electronic interactive whiteboards), call control and speech recognition with non-real-time communication services such as unified messaging (integrated voicemail, e-mail, SMS and fax).

UC is not necessarily a single product, but a set of products that provides a consistent unified user interface and user experience across multiple devices and media types.

The Session Initiation Protocol (SIP) is a communications protocol for signaling, for the purpose of controlling multimedia communication sessions.

Internet telephony, business IP telephone systems, service providers and carriers use SIP.

SIP can be used to set up and control voice and video calls, as well as instant messaging.

The most common application of SIP is the setup and termination of Voice over IP (VoIP) telephone calls.

An Internet service provider (ISP) is an organization that provides services for accessing and using the Internet.

Internet service providers may be organized in various forms, such as commercial, community-owned, non-profit, or otherwise privately owned.
