Voip Telephony Systems

In the last decades, companies all over the world used traditional PBX systems that require distinctive networks for data and audio transmissions. But with the latest revolution in the Voip telephony domain, more and more companies prefer PBX Voip systems which have a huge advantage - they make a connection between all used networks for audio and data transmissions.

Voip, which is the abbreviation for Voice Over Internet Protocol, basically means sending the audio flux by using the networks which are defined by an IP number. Although it was first designed for data transmissions, the Internet Protocol concept started to be used for audio transmissions as well, as a result of the huge success it had as an universal standard for transmission of information. By using Voip service systems, their users are not restricted to only making or receiving phone calls on the IP networks, but also traditional telephone lines can provide even a better quality and more availability.

By using a Voip port, PSTN telephone lines can be transformed in Voip/SIP telephone lines. So, the Voip port allows the user to make and receive phone calls using common telephone networks.

PBX Voip systems offer mobility for all its users, flexibility for the companies that are extending because they are easier to use than the old PBX system and they can also reduce the costs of the telephone network administration.

But how does an IP PBX Voip telephone system work?

A Voip/IP PBX system is formed by one ore more SIP or Voip telephones, an IP PBX server and it optionally includes a Voip Portal. The IP PBX server is similar to a proxy server: The SIP clients - whether they are software telephones or telephones based on hardware - are registered on the IP PBX server and when they want to make a phone call they ask the IP PBX to establish the connection.
