Listen to the future of telecommunications.

From a small 5 person insurance company to a healthcare provider with dozens of employees and departments, the Vertical Wave IP 2500 is a robust and scalable solution for your growing telephone needs. As it becomes more difficult to find parts for older failing PBX systems, or if you have simply outgrown its capabilities, the time to invest in cutting edge telecom technology is now.

As an authorized dealer and installer of Vertical products, we have access to the top levels of support. Let us meet with you, face to face and discuss your needs and where you would like to see your business go.

We don’t just provide the equipment, we also have long-standing relationships with local service providers. This allows us to offer not only the best deals and the best support, but a single phone call solution. We strive to be your single point of contact for all your network and telephone needs.
