These two Avaya voice terminals offer the same unique "look and feel" of the DEFINITY 6400 Series, plus these important extras:
- "Module-ready" means you can add functionality when and where you need it, including an analog fax machine, modem or analog full-duplex speakerphone
- Built-in headset jack eliminates the need for a headset adapter, reducing costs, eliminating desktop clutter and providing a more intuitive interface (requires 3124-HIC Interface Cord)
- Improved speakerphone
- Perfect for telecommuting: Class B certified for use in residential locations with DEFINITY Extenders - Complies with European CIEPR Class B standard
