Telephony, simply put, is a technology that allows individuals to communicate with each other at a distance, and IP telephony is the aspect of communication that allows individuals to communicate with each other at a distance via the Internet. Allows IP telephony is becoming an increasingly popular form of communication, often replacing traditional telephone (older phone) systems.
IP phones, sometimes called VOIP telephones, are designed for SIP phones or softphones VOIP, and are connected to data networks (or broadband routers in small businesses) rather than phone networks.
Internet protocol telephony (IP telephony) networks are used to create, provide, and access voice, data, or other types of telephone communication. IP telephony is an IP-based network that provides traditional telephonic communication over the Internet - through the Internet Service The provider (ISP) or directly from the Telecommunication service provider. IP Telephony also supports video communication between two or more users.
In simple words
IP telephony (Internet Protocol Telephony) is a technique that uses packet-switched connections to Internet protocols to transmit voice, fax, and other types of information in traditionally dedicated circuits of public switched telephone networks (PSTNs). Carried out on switched connections. The calls travel as packets of data over the share lines in a reliable flow to the user.
Components of IP Telephony
The IP telephony system is composed of these basic elements:
· End device
These may be IP phones, traditional telephones / or audio-equipped personal computers.
· Gateway
Traditional telephones handle signal translation between devices and IP network devices.
· Gatekeeper / Proxies
Gatekeeper/proxies manage central calls such as user location, authentication, bandwidth management, address translation, etc.
Benefits of IP Telephony
· Low cost of voice network
· Reduce device administration costs
· Centralized network control and management
· Enhancing customer satisfaction through the use of distributed call center applications
· Enhancing communication capabilities and productivity for remote and mobile employees
How IP Telephony Works
IP telephony uses the “Internet Protocol” to communicate over the Internet via digital means. By using this technology instead of traditional phone systems, business owners can leverage hardware and applications with an Internet connection to communicate more effectively.
By taking advantage of IP telephony, the user can connect voice, data, video and multimedia technologies together that are digitally based.
