I do not use VOIP. I have found that many people who use VOIP from their home, experience call quality issues. In some cases, the calls will drop but mostly the issues seem to be calls breaking up and the person on the other end of the line having issues understanding what is being said. These issues are most likely due to the internet service available at the house. For VOIP to be reliable, you must have very good internet service and one where voice traffic can be prioritized over things like gaming and streaming.
