VelocityTel vs VoiceIP Solutions

I signed up for this service because of the good reviews from voip review. I have a business with 8 phones. I was told that if i had a fast connection then i wouldn't have any problems. I invested $5000 in a new network when we moved offices and we have a 5MBps dedicated connection. It took a few weeks for our phone number to be ported. Customer service was friendly but never fixed problems even though we had many support tickets and they were escalated to top level support. The phones that they recommended were the GXP 2000's and they are of cheap quality. We often have echo's and occasionally get disconnected. We have to reset our phones frequently to avoid problems. The main complaint i have is the quality and reliability of calls. The quality of my cell phone calls is much better than my voip ones. I just tell people to call my cell to avoid being disconnected. Overall we saved money on the service but more than payed for it on our network and time lost. Use a reliable provider or standard service
