Future-proof Your Business Communications with ITC’s Landline Replacement Solutions
ITC provides cost-effective, reliable landline replacement plans designed for businesses, property management companies, and associations throughout Chicagoland. As major telecom carriers phase out traditional POTS copper lines (many targeting 2029), we’re at the leading edge with modern alternatives that preserve critical devices, help maintain compliance, and reduce costs. Powered by an all-in-one solution that runs on a dedicated wireless network, we make migration simple—so you can keep using elevators, fire alarms, door entry and security systems while saving money.
