I like the way that it is easy to set up a new device, and is easy to configure and keep up with changes. The customer service is average at best. I do not like that it is expensive, and that there are a lot of steps to do simple things. I would recommend that you find a different product. I am able to use my existing telephone system and still be able to use my voice recognition. Colt Cloud Phone Systems is a great tool for us to use. It is very easy to set up and use. The customer support is also very helpful and responsive. There are not many things that I dislike about Colt Cloud Phone Systems. I would recommend Colt to anyone looking for a great VoIP phone system. We have been using Colt Cloud Phone Systems for about a year now and it has been a great tool for us. We have been able to cut down on our phone bill and improve our customer service.
