Proprietary - Siemens

Designed for top level management and executives, the open interface design of the Siemens Openstage 80T allows synchronisation with PDAs and mobile phones. This makes it ideal for those who are not always desk-based.
The Siemens Openstage 80T phone is compatible with the HiPath 500, 3000 or 4000 telephone systems and is available for HFA and SIP environments.
This full duplex, hands free telephone with integrated microphone and loudspeaker, can support the addition of the Openstage Key Module 80 for add-on features.
