Most stations still use POTS (Plain Old Telephone System) lines to supply their IFB feeds. Television broadcasters need ways to reduce costs and stay within budgets and using POTS lines can burn a lot of cash. We built EarShot IFB to bring the power of VoIP (Voice-over-IP) to IFB technology.

Comrex EarShot IFB is a hardware-based system that delivers live audio feeds to callers. EarShot IFB is designed to provide telephone-based live studio program and IFB audio to field-based remote broadcasts, like TV ENG reports. Up to 30 callers can dial in and listen to the audio feeds this makes it possible to replace up to 30 POTS lines with one simple box.
