A softswitch is a call-switching node in a telecommunications network, based not on the specialized switching hardware of the traditional telephone exchange, but implemented in software running on a general-purpose computing platform. Like its traditional counterparts it connects telephone calls between subscribers or other switching systems across a telecommunication network. Often a softswitch is implemented to switch calls using voice over IP (VoIP) technologies, but hybrid systems exist.
An analog telephone adapter (ATA) or FXS gateway, is a device for connecting traditional analog telephones, fax machines, and similar customer-premises devices to a digital telephone system or a voice over IP telephony network.

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).
Sipgate, stylised as sipgate, is a European VoIP and mobile telephony operator.
Poly, formerly Polycom, a part of HP Inc., is an American multinational corporation that develops video, voice and content collaboration and communication technology.
This is a comparison of voice over IP (VoIP) software used to conduct telephone-like voice conversations across Internet Protocol (IP) based networks. For residential markets, voice over IP phone service is often cheaper than traditional public switched telephone network (PSTN) service and can remove geographic restrictions to telephone numbers, e.g., have a PSTN phone number in a New York area code ring in Tokyo.
Mobile VoIP or simply mVoIP is an extension of mobility to a voice over IP network. Two types of communication are generally supported: cordless telephones using DECT or PCS protocols for short range or campus communications where all base stations are linked into the same LAN, and wider area communications using 3G or 4G protocols.
Sipura Technology, Inc. was a voice-over-IP (VoIP) startup company based in San Jose, California founded in 2003 with its siblings VideoCore and Komodo Technology, Inc.

The Linksys iPhone was a line of internet appliances from Cisco Systems. The first iPhone model – released by Infogear in 1998 – combined the features of a regular phone and a web terminal. The company was later purchased by Cisco and no new products were marketed under the name between 2001 and 2006. At the end of 2006, Cisco rebranded its Linksys VoIP-based phones under the name, shortly before Apple released an iPhone of its own. This led to a trademark dispute between the two companies, which was resolved on February 20, 2007.
Google Voice is a telephone service that provides a U.S. phone number to Google Account customers in the U.S. and Google Workspace customers in Canada, Denmark, France, the Netherlands, Portugal, Spain, Sweden, Switzerland, the United Kingdom and the contiguous United States. It is used for call forwarding and voicemail services, voice and text messaging, as well as U.S. and international calls. Calls are forwarded to the phone number that each user must configure in the account web portal. Users can answer and receive calls on any of the phones configured to ring in the web portal. While answering a call, the user can switch between the configured phones. Subscribers in the United States can make outgoing calls to domestic and international destinations. The service is configured and maintained by users in a web-based application, similar in style to Google's email service Gmail, or Android and iOS applications on smartphones or tablets.
Microsoft Response Point was an advanced software-based telephone system developed by Microsoft. Response Point, a PBX system targeting small businesses with less than 50 employees, was launched in March 2007, with systems available on the market in the fourth quarter of that year. Response Point is VoIP-based, and uses SIP as its signaling and call setup protocol. Response Point supports voicemail and multi-party calling in addition to two party VoIP calls. Response Point features innovative voice recognition technology to manage calls and voice mail. Voicemail messages can, optionally, be sent to e-mail where they can be retrieved and archived. Response Point voice dialing can work with the Response Point phone directory which is currently limited to 1100 contacts per user. Contacts may be imported from the Windows Address Book or Microsoft Outlook. Response Point automatically detects gateways and phones connected to the network.

Wideband audio, also known as wideband voice or HD voice, is high definition voice quality for telephony audio, contrasted with standard digital telephony "toll quality". It extends the frequency range of audio signals transmitted over telephone lines, resulting in higher quality speech. The range of the human voice extends from 100 Hz to 17 kHz but traditional, voiceband or narrowband telephone calls limit audio frequencies to the range of 300 Hz to 3.4 kHz. Wideband audio relaxes the bandwidth limitation and transmits in the audio frequency range of 50 Hz to 7 kHz. In addition, some wideband codecs may use a higher audio bit depth of 16 bits to encode samples, also resulting in much better voice quality.
Web-based VoIP is the integration of voice over IP technologies into the facilities and methodologies of the World-Wide Web. It enables digital communication sessions between Web users or between users of traditional telecommunication services.
