Callisto Communications

About Us


Callisto Communications is a marketer specializing in sales and repair of Nortel telecom equipment, headsets, and MCK, Cisco, Adtran, Kentrox, ShoreTel, and Toshiba product lines to name a few. Callisto offers quality products, on-time delivery, and a support staff that delivers outstanding customer service.

We focus on getting the little things right. Parts arrive with all components properly packaged. With a high level of quality control, our defective rates are extremely low. Our warranty is strong. Our proven track record with you reinforces this. This is reinforced in your use of Callisto in high-level, “escalated” customer situations. When it absolutely has to be there, on time and correct, Callisto gets the call. Callisto understands the importance – and more importantly, the cost – of getting it right the first time. Both in hard financial terms, and also in customer down time and customer satisfaction. We specialize in being your silent partner. At Callisto, we have more engineering and technical expertise than most of our competitors combined.
