There are a few sites listing customer reviews which can be used as a reference. However, please bear in mind that these reviews can be tainted and since the quality of VoIP service is affected by other factors (e.g. quality of broadband connection), it is not uncommon to find both good and bad reviews for the same company. If in doubt, you can always call the VoIP companies to express your concern and ask for clarification.
