Teleco has been our service company of choice on both old and new telephone systems in our three offices. They have seasoned technicians with years of experience, that don't flinch at any level of issue. Just recently our phone system of 26 years just died on Friday, Teleco ordered and had the new system, including new handsets, installed and functioning before lunch on Monday! Now that's quick, reliable service when I needed it the most. Our telephones are critical to our company's success, and Teleco has been the answer for over 15 years.
