New York's Metropolitan Transportation Authority is expanding its contract with Ribbon Communications to modernize a phone backbone that serves roughly 70,000 employees, Fierce Network reported. Ribbon's G5 Media Gateway will convert analog lines to SIP so they can work with the MTA's existing Ribbon C20 call controller, and NUSO will replace the legacy contact center infrastructure. Each G5 chassis supports up to 768 plain old telephone service (POTS) lines.
Ribbon said the deployment is designed for a seamless transition from legacy TDM PBX environments to SIP while preserving existing analog investments and keeping operations running. No timetable was disclosed. Ribbon also noted that more than 40,000 TDM switches still support over 800 million lines worldwide, a reminder that plenty of organizations still depend on copper and legacy switching.
Most businesses won't need 768 analog ports, but the approach scales down. Copper POTS line replacement is rising on many to-do lists as carriers retire legacy services and prices climb. Fax lines, alarm panels, elevator phones, door entry and gate phones can often move to SIP through analog adapters or gateways, while desk phones move to a hosted VoIP phone system. A phased migration keeps the critical lines working while everyone else gains AI transcription, mobile apps and CRM integration.
