The quality of VoIP

Telephone, voice over Internet Protocol (VoIP) protocol is a PBX telephone system based on the Internet instead of Ma Bell.

Communicate with a computer or a computer combination of VoIP phones and analogue telephone connection. Software provides the connection interface. One of the reasons to VoIP use are cheaper than analog system, even for long distance calls.

Definition

VoIP can transmit video and audio sounds.

In the two forms of communication quality whether experience a good or a bad thing is seen or heard. Communication is clear or not. Quality means no error in the audio or video signal. Reception is solid, and there is no delay. In a normal phone call, there is no delay because the connection on the circuit is still intact at the other end as a string. Is VoIP digital packets (sequences of 1 and 0) for the connections represent such as beads one is placed after the other. A good connection means that the packets in order and without delay arrive.

Measurement

(Voice quality can be expressed through a series of numbers from 1 to 5, 1 is the worst, unable to communicate) and 5 at best (perfect - just like the radio).

This is the average of MOS MOS or referred to notice. Part the metric to measure the quality, VoIP and some service agreements give a specific value of MOS.

Factors

Quality and reliability are each VoIP call from essential.

The complaint must be clear and the signal must be reliable. Connectivity bandwidth affects the quality and Zuverlässigkeit.Bandbreite is similar to a pipe: as the pipe theWater more can drain. VoIP rate transfer or speed affect bandwidth. Slow transfers the debacle of the voice can cause problems. At least cable or a DSL connection is the preferred technology.

Effects of time

Weather such as thunderstorms, heavy rain, electrical impulses or strong gusts can affect the quality due to static interference cause.

Usually, the error is not very striking example. If you download files or surf the Internet, but if you hear the voice, it can be very disturbing. Turn off and then reinstalling the power of VoIP devices can delete static connection.

Telephone frequencies

It is not uncommon for IP phone frequency interference with other VoIP devices cause.

This is because IP packets in the media. Enter the frequency as you move can exit to a target, and the media, especially if the connection is wireless. Change the phone with a lower frequency (e.g. 2.4 GHz) can solve the problem.
