Background

The hosted VoIP service is gaining popularity like other cloud-based infrastructure services. SMBs prefer hosted VoIP solution to cut down costs and operational overhead. In addition many providers offer attractive build-in features on top of the standard service.  As opposed to other IT services, VoIP is more delicate and if not handled correctly it will cause degradation in audio quality. From time to time we are being contacted by companies that are using hosted VoIP services and suffer from poor audio quality. Usually they complain about issues of echo & noise.

Echo

Echo is one of the most disturbing artifacts in telephony. Once it appears during a call, it is so annoying that is unlikely that the call could last much longer. There are many reasons for the appearance of echo but one of the factors that amplify the echo is the long delay. For more details, read the following post on echo in VoIP . Cloud based solutions are usually increasing the delay and therefore increasing the likelihood of suffering from echo.

Noise (both static noise and ambient noise)

The problem of noise is usually due to the equipment that is being used. Sometimes the phones or ATAs generate a static noise and/or does not cancel the ambient noise.  The problem can even be caused by the network equipment on the cloud. In addition absence of network noise cancellation might contribute to this disturbing phenomenon.
