ACC Telecom Brochure

Recognized for excellence in sales and service, The Harbor City Corporation (t/a ACC Telecom), was founded in 1979 by Barry and Susan Hunt as a business machine and supply communications company.

Becoming increasingly aware of the growing business communications, telecom, voice and data cabling, and business phone system needs in the 1980’s, Mr. & Mrs. Hunt expanded their product line and established their company headquarters in Frederick, Maryland (MD) to serve the Maryland, Virginia (VA) and Washington D.C. areas. ACC Telecom quickly grew to the area’s leader in business phone system installations, service and voice and data cable infrastructures.

In 1991, ACC Telecom relocated its headquarters to Ellicott City, Maryland. ACC Telecom’s fast-growing client base created the need for a more centralized location. In order to better serve the Baltimore, Maryland, Northern Virginia and Washington, DC corridor, Mr.& Mrs. Hunt selected Columbia, Maryland. The Columbia headquarters allows us to efficiently support the needs of our customers in the Baltimore-Washington Metropolitan areas.

In 2002, ACC Telecom provided the first Cloud-Hosted PBX in Maryland.  Using Broadwork/Broadsoft Cloud Licenses (the creators of VoIP Technology), ACC secured contracts with Baltimore City and other local enterprises.  ACC was one of the very first adopters of this brand-new revolutionary technology, however, the technology was before its time and the world was not ready for VoIP at the end user level in 2002.  Five years later, we revisited VoIP technology and began offering our very own ACCloud cloud-based phone system and SIP Trunks.  We now offer a variety of VoIP solutions including, three flavors of cloud-based phone systems (standard, advanced, & enterprise), SIP Trunk solutions, and Voice over IP phone systems that are available for use on-premise or in a virtual server environment.  You’ll be hard-pressed to find another local vendor that knows more about VoIP technology, VoIP installations, and VoIP troubleshooting than ACC.
