  • Audio quality will depend on a number of factors that together will determine the quality of your VoIP calls.
  • Available up and downstream bandwidth alone is not an indicator of an internet connection's suitability for use with VoIP. Other considerations e.g. latency, jitter and local network setup must be taken into account.
