In short, yes it does. The quality of a VoIP call is similar, if not better to that you find on a regular landline telephone service. In many cases, we can offer "High Definition" quality on calls.
The biggest factor that affects call quality is your internet connection and the bandwidth you have available. In most cases, VoIP calls are prioritized, so even if your internet connection is busy, your calls should remain clear.
We will discuss your requirements during the sign up process, to advise on bandwidth requirements, but in most cases, a standard UK fibre connection is more than enough.
