Ensuring voip quality is a skill not learned without experiencing poor voip quality.  Remember the early days of Skype?  Unintelligle or broken speech.  Sometimes it was good and mostly bad.  It was quite hit and miss.  Why?

VoIP quality is a matter of all the bits of “noughts and ones” being transmitted from the sender and arriving at the receiver in REAL TIME.  Delays of seconds make conversations impossible.  Also as the “0’s and 1’s” are collected in packets and some are sent over different routes to others, they could arrive out of order.  They have to be put into the correct sequence before being converted back into sound.  So if any of them are missing you get disjointed words.  This is what voip quality is about.  So HOW do you ensure voip quality?

A function called QOS (Quality-of-Speech) in available in Layer 3 (and above) routers, switches, bridges and multiplexers that comprise the data transmission infrastructure of businesses and the internet.  This prioritises voice-packets over data-packets giving a higher chance that real-time voice-communications can occur.

However, voip quality is NOT GUARANTEED across large networks, especially the world-wide-web.

As such every business should only consider voip for internal calls.  Those to customers, clients and suppliers are made under the understanding they may not be the best voip quality.
