About VoIP Phone Systems

There are tons of companies creating VoIP Phone systems for the business purposes. They are very helpful in lessening the cost of communications to the company, be it for internal and external calling. Installation of VoIP phone systems not only lessens operational costs, but also gives flexibility to the user, making it a top choice in today’s markets.

VoIP phone systems refer to those systems that are connected to the Internet and have telephone voice, fax and/or voice messaging applications. VoIP is connected to the Internet and not the public switched telephone network (PSTN).

The first step involved in the installation of the VoIP system is that the analogue signal is converted into a digital format in which the signal is compressed or translated into an Internet Protocol (IP) packet, all set to be transmitted over the Internet. At the receiving end, this process is reversed. The system uses session control protocols to manage the tear down and set up of calls.

It also involves audio codecs, which encode the speech. This permits it to be transmitted over an IP network as digital audio through an audio stream. Codec stands for “coder-decoder”. It is a hardware used to compress/decompress the digital audio data as per the audio file format or the streaming audio format. The use of codecs varies from one purpose to another and often a range of various codecs are used at a given time. Some implementations rely upon the narrowband and compressed speech, while others are supported by high fidelity stereo codecs.

VoIP phone systems can be tailor fitter to suit businesses of any size and can dramatically cut communication costs as demonstrated by the sizeable amount of people making the switch to VoIP systems.

Traditional phone services are available in VoIP systems too, that permit the phone companies to give you inbound and outbound calling with Direct Inbound Dialing. A lot of companies allow unlimited calls to the US and selected countries in Europe, Asia and Canada for a monthly fee, which turns out to be almost free for any company.
