Product Description

SIP-based Wireless Conference Phone Delivers a New Level of Freedom and Flexibility for Audio and Video Conferencing.

The S850i from Aastra, designed specifically for use in conference rooms, boardrooms and executive offices, employs the latest in
secure wireless audio technology. Comprised of several distinct components, the S850i redefines the traditional conference call
experience giving users unprecedented freedom with respect to placement and accessibility of the speaker, microphones and
dial pad. Supporting wideband audio technology, the S850i delivers superior sound quality and performance meeting all of your audio and video conferencing needs.

Key Features and Benefits

Wireless Freedom

No more wires on the conference room table or floor. Simply locate the wireless base unit in a convenient and inconspicuous location where it can be connected to the IP network and then place microphones, speaker and dial pad anywhere they are required in the room.

Superior Audio Quality and Performance

Two tabletop omnidirectional microphones pick up sound from all directions ensuring everyone participating in the conference call can be heard clearly. An optional wearable microphone allows for presenters to move freely about the room and still be easily heard without having to talk loudly.

Integration with Video Conferencing and PC Applications

The S850i is equipped with balanced analog audio input/output connections facilitating easy integration with video conferencing systems such as the Aastra BluStar™ for Conference Room solution. This allows the S850i microphones and speaker to be used for video calls and provides excellent acoustic echo cancellation and noise control for your video calls. PC applications, including BluStar for PC, can also be integrated with the S850i using the same balanced analog audio input/output connections.

S850i Conference Phone Components

> One handset dialer for operation and system configuration
> One wireless speaker
> Two omnidirectional tabletop microphones
> One charger tray for speaker, microphones and handset dialer, supplied with universal AC power adaptor
> One wireless base unit with 7 ft. Ethernet cable

Private Call or Conference Call

Private calls can be conducted using the handset dialer, and the call can easily be switched to conference mode to use the speaker and microphones.

Bluetooth® Connectivity

The S850i is equipped with a Bluetooth interface that supports the Hands Free Profile (HFP) allowing users to make a call using a mobile phone, computer or other device via a Bluetooth connection.

Acoustic echo canceller for speaker and microphone allows for a natural conversation. The wireless microphones are shielded to avoid interference from mobile phones and other electronic devices.

Call Manager Compatibility
