Loss of Traditional Network PSDN
PSDN call made using circuit switching.
PSDN just means that someone using a special phone call through general counsel.
In a telephone conversation this behavior is only about 50% of the bandwidth used at any given time.
This is because the calls are usually two people, one person listening to one person speaking, which reduces bandwidth.
This is much reduced if there is a pause in conversation as a natural pause between words, people think, and so on, when the breath of a reliable connection, of course, for voice transmissions, but the weakness is that it is not effective in its use of bandwidth.
This relative cost of the phone constantly, until now, but it provides VoIP solutions:
A more effective use of bandwidth.
Benefits VoIP
Voice over IP (VoIP), is a way to convert analog signals while using the phone, a digital format (wide web) and then again when the analog receiver.
VoIP networks, digital voice data is compressed in packets over IP networks.
Using Bandwidth, VoIP networks can carry many times the number of voice calls as a switched circuit network PSDN.
The net result is already clear.
VoIP can cause large amounts of reserves of physical resources required for long-distance voice call. Did he do it by providing more effective use of bandwidth, one of the main weaknesses of the traditional telephone network.
There is, far more than just sending VoIP packets over the Internet.
There are agreed protocols for how computers find each other and how information is exchanged to allow packets to flow between users, there is also an agreed format, (called the payload format), which includes the media contents of the package.
Global VoIP telephony A Total Solution
