After logging into the CharTec VoIP System, I was wowed! The systems ease of configuration is incredible. It is really simple and straight-forward. From building the dial plans, to setting the system up on the network--the install just flows. the HUD (Heads Up Display) is an amazing feature and the unified communication is great! I love that I don't have to download a third-party application like Yahoo! or Communicator for chat. It's built right in to HUD! Fax to e-mail--a can't live without! A favorite for my clients and me is the ability to see who is on the phone without having to look at my phone. This product is a great value add to my business and to my clients. A marvelous VoIP offering!
