Electronic Hook Switch (EHS) Cable works with Siemens phones to enable remote answering functionality, with your wireless headset. 

This means you will be able to answer telephone calls while away from your desk.  You will hear the telephone ring in your wireless headset, then at the touch of a button you can answer the call.

Not all Siemems telephones are engineered to use EHS cables.  Please refer to the PDF on the left to find out which telephones are EHS compatible and how to set-up the CA113 EHS Cable.
