I have been a customer of Black Diamond VoIP Consulting Inc. for several years now and I must say that their services are average. The call quality is not always consistent and there have been a few instances where there were connection issues. However, their customer support is always quick to respond and help resolve any issues that arise. Overall, I would consider their services to be satisfactory.
