Voice and video calls through computer networks has become popular throughout the world since the beginning of the XXI century and is now widely used by private users and the corporate sector. The use of IP-telephony systems allows telecom operators to significantly reduce the cost of calls (especially international), and integrate telephony services with the Internet, to provide intelligent services.
VoIP technology realizes the problem and solutions that are using technology to implement PSTN will be more difficult or more expensive. Ability to transmit more than one telephone call within the high-speed telephone connection. Therefore, VoIP technology is used as a simple way to add extra phone line at home or office. Secure calls, with a standardized protocol (such as SRTP). Most of the difficulties to enable secure telephone connections to the traditional telephone lines, such as the digitization of the signal, digital signal transmission, have been solved in the framework of the technology VoIP. It is only necessary to produce a signal encryption and authentication for an existing data stream. Location independence. One need only an Internet connection to connect to your ISP VoIP. For example, call center operators with VoIP-phones can work from any office where there is available an effective fast and stable Internet connection. Available integration with other services via the Internet, including video calls, messaging and data during the conversation, audio conferencing, managing address book and receive information about available is to call other subscribers. Additional phone features - such as routing calls, pop, alternative GSM-roaming and implementation of IVR - easier and cheaper to implement and integrate. The fact that a call is in the same data network as the PC user opens the door to many new opportunities. Portability of telephone numbers (English Mobile number portability, MNP and LNP, Eng. Local Number Portability) - a service that allows its users to keep an existing phone number from one mobile operator to another. Ability to transfer phone numbers depends on the laws of the country. Challenges in IP-telephony system is considered the least cost call routing (LCR, Least Cost Routing system), which is based on the fact that checks the destination of each telephone call as soon as it is made within the network that gives the consumer the lowest price. Therefore, VoIP-solutions are also needed to manage the compatibility of mobile numbers of MNP when routing a voice call. In countries without a central database, such as the UK, it is sometimes necessary to send a request to the GSM-network on which network (which operator) owns the cell phone. Because VoIP is beginning to gain momentum in the market companies through the use of system features a minimal cost call routing, you must provide a certain level of reliability in the management of calls.
