Basics of IP Telephony

Today, there are numerous people that make calls over the Internet, without even noticing. Technology experts refer to this technology as “Voice over Internet Protocol,” or in short VoIP. Here, the calls are input digitally, shredded and transmitted in data packets over the network. When it is received at the called party, the data packets are reassembled in the correct state and output as sound. It really doesn’t make any difference whether the data packets are transmitted via the mobile or landline. The faster the Internet access is, however, the better phone calls can be made without compromising the quality of voice.

In private sectors, VoIP Hosting services are spread very rapidly. In the business environment, however, voip services were not used because of the fluctuating transfer rates, restrictions in the area of security and availability. The advanced IP telephony with the Internet telephony has little in common thanks to the advanced network technology and the growth of the broadband Internet. IP telephony offers an important advantage Cost for both the end users and the network operators. The users can make cheaper phone calls, especially international calls using the IP Telephony.

How does IP Telephony Work?

The IP telephony, the language (voice) is bifurcated into data packets that are sent through the network (local or Internet). Unlike the digital fixed-line telephony (ISDN), in which the voice is transported continuously on a dedicated line with a fixed amount of bandwidth, which creates a danger of poor voice quality when data packets are received with a long delay at the receiver.

Here, IP telephony transmits the voice data packets along with the other data packets (eg: email, databases, etc.). In order to prevent poor voice quality, voice transmissions are automatically compressed when less bandwidth is available. Therefore, the data packets are sent faster and smaller offering greater voice quality.

The VoIP Dedicated Hosting servers are ideal for making cheap local and international phone calls and minimizing hardware costs. It offers various features such as Call Monitoring, Call Recording, Call Routing, Call Transfer, Call Waiting, Remote Call Pickup, Three-way Calling, Voicemail to email, Computer-Telephony Integration and a Web Interface to manage your phone calls.
