Siemens Enterprise Communications Product Characteristics Common functionality / Target Platforms Protocol  (Enhanced) CorNet TS Interfaces  U P0E Acoustics  Full Duplex Hands free talking Others  Graphical Displays Target Platforms  Compared to optiset E and optiPoint 500 the OpenStage Phones provide larger displays and show lots of usability / User Interface enhancements. To achieve this the CorNet protocol had to be enhanced. These changes are only part of the new HiPath platform versions (3000 V7 and 4000 V4), meaning the OpenStage T phones are not downward compatible to older HiPath versions.
