Plantronics CS500 series Siemens EHS*

The CS500 series headsets use the Plantronics Electronic Hookswitch for Aastra & Siemens Phones to work with the following Siemens phones:

OpenStage 40

OpenStage 60

OpenStage 80

Optipoint 410 (all models)

Optipoint 420 (all models)

Optipoint 500 (all models)

Optipoint 600 (all models)

The Optipoint phones do NOT have a headset jack and require an “Acoustic Adapter” to connect with these phones. This is not a part that we carry and would need to be ordered through your phone vendor

The OpenStage phone models do not require and adapter.
