Your IT department, your phone company and your cabling crew
Most businesses juggle a phone vendor, an IT shop and an electrician who do not talk to each other. TDS is all three: Long Island IT support, phones and cabling from one team. The technician who installed your phones knows your network, and the helpdesk that answers knows both.
