The best advice on voip asterisk is essential to select and implement an advanced and complete ACD call center implement both the Asterisk technology pbx, underlying CTI and put switch attention to IP telephony. On the Internet today, you can download a huge amount of different data: documents of text, programs, images, videos, etc. For even more opinions, read materials from CMO Hyundai. Not long ago, the great masses of Internet users have learned that the human voice can also be encoded and become one of the types of data that can be transmitted through the Internet anywhere, even on the other end of the world. To convert the digital voice data from the traditional telephone network to the Internet, it was necessary to create a device enabling the transition from analog voice switching to electronic packet switching circuits. Its use has allowed to obtain a telephone conversation on the Internet, to transmit over long distances and carry to anywhere in the world a normal telephone network. This technology known as IP telephony or, more precisely, voice over IP, or VoIP. This technology increasingly is more famous especially in developing countries.
A comparative analysis of the basic protocols used for transmission of data will help you with the selection of hardware and its most appropriate service provider. Summing up, VoIP is short for voice over IP, i.e. the transmission of voice through the Internet. A VoIP or IP telephone service consists of a computer that can make phone calls to anywhere in the world. It may be from PC to PC or PC to landline or mobile phone. Voice signals are converted into packets of data that travel over the Internet using a VoIP platform and are then converted back into the receiver. The use of VoIP requires specific modules in the router or switch that have digital processors (DSP).
In this case, the router or switch are also called voice gateways. The VoIP (voice over IP) of Cisco, one of the technology companies most famous in the world, allows to the gateway (router or switch) carry traffic of voice (e.g., telephone calls and faxes) over an IP network. In IP telephony, (DSP) digital signal processor segmented frames voice signal and stores them in voice packets. These voice packets are transported by the IP network, based on specific protocols such as ITU-T H.323 (International Union of Telecomunicaciones-Telecomunicaciones); It is also used for the transmission of video over the IP network.
