SoundStation2 Avaya 2490 is the ideal conference phone for Avaya DEFINITY digital PBX environments. Just connect the conference phone directly into a DEFINITY ECS digital wall jack. You don’t need an analog port, analog adapter, or complicated connections to take advantage of Polycom’s legendary voice quality in your conference rooms.

Polycom Acoustic Clarity™ technology delivers exceptional performance and voice quality, making your conference calls clearer and more productive. Industry-leading full duplex technology provides natural, simultaneous two-way conversation without clipping or drop-outs that are common in traditional speakerphones. Users can speak in a normal voice and be heard clearly up to ten feet away – making every call a more productive call. Dynamic Noise Reduction (DNR) actively removes background noise such as projectors and ventilation systems, while 360-degree microphone coverage with intelligent mixing highlights the person speaking, not the distracting ambient sounds, for crystal clear conferencing. It also features technology that resists interference from mobile phones and other wireless devices, delivering clear communications with no distractions.

SoundStation2 Avaya 2490 provides users with advanced features, enabling conference calls that are more flexible and productive than ever before. Add up to two optional Expansion Microphones, ensuring that the microphone pickup reaches to all corners of a medium-sized conference room. The 2.5mm Applications Port allows you to connect the SoundStation2 Avaya 2490 to a mobile phone for conference calls from locations without phone lines, or to a computer for Internet calling. A large backlit display offers easily visible call information and telephone functions. With traditional telephone features like redial, mute, transfer, and hold, you have a conference phone that’s also familiar and easy to use.
