Yes, many businesses have experienced savings of up to 50% on their monthly telephone bill, especially companies that make a lot of international calls, or make a lot of calls between their company branches.
If that doesn't sound like your business, then don't worry there are still plenty of ways to save money with Voice over IP.
For instance, a typical VoIP service will allow multiple simultaneous calls over a single VoIP "line", unlike a regular telephone line that only allows one call at a time. So your business may be able to disconnect some of your extra phone lines and therefore save your monthly line rental.

We constantly surpise people we are talking to on the phone when we mention that the call is being made over the internet. To the average user, there is no noticeable difference between a Voice over IP call and normal call.

The biggest threat to call quality is a congested internet connection, which could cause break ups or drop-outs in the call. To prevent this from happening, the Quadro PBX has a built in internet router, so it can act as the gateway to the internet for your computers and phones. In place as the internet gateway for your network, the Quadro prioritises your phone calls over other traffic like emails and web browsing. Giving priority to phone calls ensures that a congested internet connection does not cause drop outs.
