CTS supports a wide variety of telecom brands, with many types of equipment available including VoIP systems. Because some of these systems are out of date we are not always able to get the parts to fix some of these legacy phone systems. So if your company is utilizing a phone system that works for you, but you need to replace a component that is no longer functioning, we will do our best to find that part so we can replace it.
