- https://en.wikipedia.org/wiki/Telepresence - refers to a set of technologies which allow a person to feel as if they were present, to give the appearance of being present, or to have an effect, via telerobotics, at a place other than their true location. Telepresence requires that the users' senses be provided with such stimuli as to give the feeling of being in that other location. Additionally, users may be given the ability to affect the remote location. In this case, the user's position, movements, actions, voice, etc. may be sensed, transmitted and duplicated in the remote location to bring about this effect. Therefore information may be traveling in both directions between the user and the remote location.
A popular application is found in telepresence videoconferencing, the highest possible level of videotelephony. Telepresence via video deploys greater technical sophistication and improved fidelity of both sight and sound than in traditional videoconferencing. Technical advancements in mobile collaboration have also extended the capabilities of videoconferencing beyond the boardroom for use with hand-held mobile devices, enabling collaboration independent of location.
- https://en.wikipedia.org/wiki/Teleconference - or teleseminar is the live exchange and mass articulation of information among several persons and machines remote from one another but linked by a telecommunications system. Terms such as audio conferencing, telephone conferencing and phone conferencing are also sometimes used to refer to teleconferencing.The telecommunications system may support the teleconference by providing one or more of the following: audio, video, and/or data services by one or more means, such as telephone, computer, telegraph, teletypewriter, radio, and television.

- https://en.wikipedia.org/wiki/Telecollaboration - a form of network-based language teaching which emerged in language teaching in the 1990s. It refers to the pedagogic practice of bringing together classes of foreign language learners through computer-mediated communication for the purpose of improving their language skills, intercultural communicative competence and digital literacies. Telecollaboration, also increasingly referred to as online intercultural exchange (OIE), is recognized as a field of computer-assisted language learning as it relates to the use of technology in language learning. Outside the field of language education this type of pedagogic practice is increasingly being used to internationalize the curriculum and offer students the possibility to engage with peers in other parts of the world in collaborative online projects. Different terms are used to refer to this practice, for example virtual exchange, collaborative online international learning (COIL), and globally networked learning. Telecollaboration is based on sociocultural views of learning inspired by Vygotskian theories of learning as a social activity.
- https://en.wikipedia.org/wiki/H.323 - a Recommendation from the ITU Telecommunication Standardization Sector (ITU-T) that defines the protocols to provide audio-visual communication sessions on any packet network. The H.323 standard addresses call signaling and control, multimedia transport and control, and bandwidth control for point-to-point and multi-point conferences. It is widely implemented by voice and videoconferencing equipment manufacturers, is used within various Internet real-time applications such as GnuGK and NetMeeting and is widely deployed worldwide by service providers and enterprises for both voice and video services over IP networks. It is a part of the ITU-T H.32x series of protocols, which also address multimedia communications over ISDN, the PSTN or SS7, and 3G mobile networks.
- http://en.wikipedia.org/wiki/Voice_over_Internet_Protocol - 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).
The steps and principles involved in originating VoIP telephone calls are similar to traditional digital telephony and involve signaling, channel setup, digitization of the analog voice signals, and encoding. Instead of being transmitted over a circuit-switched network, the digital information is packetized, and transmission occurs as IP packets over a packet-switched network.

- https://en.wikipedia.org/wiki/Federated_VoIP - a form of packetized voice telephony that uses voice over IP between autonomous domains in the public Internet without the deployment of central virtual exchange points or switching centers for traffic routing. Federated VoIP uses decentralized addressing systems, such as ENUM, for location and identity information of participants and implements secure, trusted communications (TLS) for identify verification.
- https://en.wikipedia.org/wiki/Internet_telephony_service_provider - offers digital telecommunications services based on Voice over Internet Protocol (VoIP) that are provisioned via the Internet. ITSPs provide services to end-users directly or as whole-sale suppliers to other ITSPs. ITSPs use a variety of signaling and multimedia protocols, including the Session Initiation Protocol (SIP), the Media Gateway Control Protocol (MGCP), Megaco, and the H.323 protocol. H.323 is one of the earliest VoIP protocols, but its use is declining and it is rarely used for consumer products. Retail customers of an ITSP may use traditional analog telephone sets attached to an analog telephony adapter (ATA) to connect to the service provider's network via a local area network, they may use an IP phone, or they may connect a private branch exchange (PBX) system to the service via media gateways. ITSPs are also known as voice service providers (VSP).
- https://en.wikipedia.org/wiki/Telephone_number_mapping - a system of unifying the international telephone number system of the public switched telephone network with the Internet addressing and identification name spaces. Internationally, telephone numbers are systematically organized by the E.164 standard, while the Internet uses the Domain Name System (DNS) for linking domain names to IP addresses and other resource information. Telephone number mapping systems provide facilities to determine applicable Internet communications servers responsible for servicing a given telephone number using DNS queries. The most prominent facility for telephone number mapping is the E.164 Number to URI Mapping (ENUM) standard. It uses special DNS record types to translate a telephone number into a Uniform Resource Identifier (URI) or IP address that can be used in Internet communications.
- https://en.wikipedia.org/wiki/VoIP_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). 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.
- https://en.wikipedia.org/wiki/Softphone - a software program for making telephone calls over the Internet using a general purpose computer, rather than using dedicated hardware. The softphone can be installed on a piece of equipment such as a desktop, mobile device, or other computer and allows the user to place and receive calls without requiring an actual telephone set. Often a softphone is designed to behave like a traditional telephone, sometimes appearing as an image of a handset, with a display panel and buttons with which the user can interact. A softphone is usually used with a headset connected to the sound card of the PC, or with a USB phone.

- https://en.wikipedia.org/wiki/Voice_over_WLAN - the use of a wireless broadband network according to the IEEE 802.11 standards for the purpose of vocal conversation. In essence, it is voice over IP (VoIP) over a Wi-Fi network. In most cases, the Wi-Fi network and voice components supporting the voice system are privately owned.VoWLAN can be conducted over any Internet accessible device, including a laptop, PDA or VoWLAN units which look and function like DECT and cellphones. Just like for IP-DECT, the VoWLAN's main advantages to consumers are cheaper local and international calls, free calls to other VoWLAN units and a simplified integrated billing of both phone and Internet service providers.

GNU SIP Witch
- GNU SIP Witch is a secure peer-to-peer VoIP server that uses the SIP protocol. Calls can be made peer-to-peer behind NAT firewalls, and without needing a service provider. GNU SIP Witch does not perform codec operations and thereby enables SIP endpoints to directly peer negotiate call setting and process peer to peer media streaming even when when multiple SIP Witch call nodes at multiple locations are involved. This means GNU SIP Witch operates without introducing additional media latency or offering a central point for media intercept or capture. GNU SIP Witch can be used to build secure and intercept-free telephone systems that can operate over the public Internet.
- GNU Bayonne traditionally operates as a generic script driven telephony server that can operate with existing third party telephony api kits, such as those produced by Intel-Dialogic, Aculab, Pika (montecarlo), or Voicetronix. GNU Bayonne also includes pure network drivers for SIP and H323. Specific drivers and api adaptions offer features unique and targetted to those environments. For example, some telephony api's support various forms of conferencing, and these features are available in Bayonne adaptions for those api's.
Common uses include voice messaging, voice broadcast, and prepaid calling in conjunction with a SIP server or H323 gatekeeper such as Ser, SipX, GNU SIP Witch or GNU Gate Keeper; for offering IMS services and for carrier hosted applications; and for integration with legacy digital and analog key telephone systems. These use cases imply that Bayonne will also assume the goals and functionality of the original Babylon PBX integration server as well.

Jami is free and open-source software released under the GNU General Public License. In November 2016, it became part of the GNU Project. Two account types are currently available, and many of each type can be configured concurrently. Both types offer similar features including messaging, video and audio. The account types are SIP and Ring. A SIP account enables the Jami softphone to connect to a standard SIP server and a Ring account can register (or use an account set up) on the decentralised Jami network which requires no central server. By adopting distributed hash table technology (as used, for instance, within the BitTorrent network), Jami creates its own network over which it can distribute directory functions, authentication and encryption across all systems connected to it.
- WebRTC - a free, open project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose. Mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols. The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others. This page is maintained by the Google Chrome team.
- https://en.wikipedia.org/wiki/WebRTC - an API definition drafted by the World Wide Web Consortium (W3C) that supports browser-to-browser applications for voice calling, video chat, and P2P file sharing without the need of either internal or external plugins.
Two peers first need to find one another. This signalling step is purposefully omitted from the WebRTC specification, since the WebRTC protocol is not specific to browsers and can be used by any number of different devices in different circumstances. Sometimes this is hindered by network topology realities, e.g. non-permissive firewalls or NAT routers. In this case it is physically impossible for the two peers to communicate in a P2P manner and a third party relay is required; this is included in the WebRTC specification in the form of a TURN server.

- Vimeo: Multiparty topologies in WebRTC
There are in general 3 main models of deploying a multiparty video conference:
- Mesh – where each participant sends his media to all other participants
- MCU – where a participant is “speaking” to a central entity who mixes all inputs and sends out a single stream towards each participant
- SFU – where a participant sends his media to a central entity, who routes all incoming media as he sees fit to participants – each one of them receiving usually more than a single stream.
I’ve taken the time to use testRTC to show the differences on the network between the 3 multiparty video alternatives on the network. To sum things up:
- Mesh fails miserably relatively fast. Anything beyond 3 isn’t usable anywhre in a commercial product if you ask me
- MCU seems the a good approach when it comes to load on the network
- SFU is asymmetric in nature – similar to how ADSL is (though this can be reduced, just not in Jitsi in the specific scenario I tried)
