In fact, we got them to install their own infrastructure for us, so that we could move forward with our project. They provided a wealth of knowledge about their products, their support staff was very helpful, and we have since upgraded to their enterprise version. We chose Switchvox because it had a lot of features that our previous provider did not offer, such as call recording, group calling, etc. It has been great to see our customers' satisfaction ratings go way up after switching over. The cost of running our system is lower than our old one, and we have fewer servers to manage. Switchvox is a superior product to any other available. I would recommend them to anyone looking for an alternative to their current provider.
