Telephony
The process of converting or transmitting voice or other signals over a long distance and then re-converting them to audible sound at the other end is referred to as telephony.

Transmission Control Protocol (TCP)
The ARPAnet transport layer protocol, which includes layers 4 and 5 of the OSI model. TCP manages TCP/IP sequential data exchange for remote hosts in a peer-to-peer network.
Store and Forward
The process of archiving a message or transmission for later playback or transmission. In contrast to real-time communication, store and forward is the foundation of all messaging systems, such as email, fax-on-demand, unified messaging, and so on. The term “store and forward” in data communications refers to the temporary buffering of packets or other data […]
Speech Recognition
Speech recognition is a technology that allows callers to speak commands to control applications.
SIP
The Session Initiation Protocol is used to initiate and terminate voice, video, and messaging communications between two or more IP network endpoints. SIP determines the location of endpoints, whether those endpoints are available, and the capabilities of each endpoint. SIP does not provide the actual means of communication between endpoints; rather, it facilitates communication sessions.
Service Provider
A company that provides services to Internet, telephone, and mobile phone users.
Real-Time
Real-time communications occur when perceptible delays between the sender and receiver are minimal and easily tolerated. Regular phone calls are made in real time. Point-to-point fax transmissions are nearly instantaneous. Voice messaging does not operate in real time.
Post Office Protocol (POP)
An Internet standard for storage and retrieval of email messages.
Point of Presence (PoP)
Public Switched Telephone Network (PSTN)
The PSTN is the world’s combined public circuit-switched telephone networks. Originally comprised of analogue telephone systems, the PSTN is now almost entirely digital and includes mobile telephones in addition to fixed telephones.
Messaging
Any method of storing and forwarding messages in computer telephony. Fax mail, voice mail, and broadcast messaging are all examples of this. The most popular voice solution is this horizontal application. Messaging systems allow for the storage and transmission of “nonreal time” communication. A recorded voice message, for example, can be stored for later playback […]
Modem
A modem is a device that converts digital signals to analogue signals and vice versa. Modems are used to send data signals (digital) over an analogue telephone network. A modem converts binary signals into tones that can be transmitted over a phone line. The modem’s demodulator converts the tones to binary code at the other […]
