Customer List


Our primary business is the installation/service/maintenance of multi-line telephone systems, voice mails, VoIP systems, SIP Trunks, and Internet Circuits for professional offices, businesses, institutions, and government agencies.  For new systems we recommend Allworx, but we also have years of experience with many others manufacturers and sell reconditioned Avaya Partner, Vertical/Comdial DX80/120, Nortel 616, CICS & MICs, & Mitel 200SX ML/EL & ICP.  Our core cable installers, telephone & IT network programmers are supplemented by our group of contract cable installers and 2 part-time office persons. We partner with Thor Computing, a Northern Illinois computer consulting & service firm, Rockford IT, who services, installs & maintains computer network and server equipment, Metro Consulting & Telephone Repair & Stride Technology Group in Wisconsin. We also represent and partner with Comcast Business, Charter Business, Voice Carrier, WindStream, Century Link & other carriers.

We provide a vast range of telecommunications equipment both new and reconditioned, including parts, headsets, cords, paging and sound systems, music/info on hold units, cable and wire runs—Category 3 (Voice) and Category 5E (Data) & Category 6 (Data). We install, repair, service, maintain, teach, consult, and program. We sell, rent, and lease. Most of our clients have from 6 to 99 phones and from 3 to 99 lines; but even if you have hundreds or just one phone, we can help you. We'll give you good advice and save you money whenever possible. We will tell you the truth about your telecommunications questions and problems—even if it isn’t exactly what you want to hear.

DCTR physically services the greater Rockford area & the I90 corridor between Rockford, IL and Janesville, WI, however we support and consult with clients and other consulting & installation companies nationwide. Our fees are reasonable and competitive.  We provide quality, efficient service at an affordable price. Our strength is our knowledge about telephone communications, cabling & programming, not just about a particular brand or type of system. We have no sales quotas to meet. We won’t steer you toward a pre-determined solution---we will show you that you have options.
