Poly Savi Office Telephone Interface Cable (85R57AA) is an accessory cable for connecting a compatible Poly Savi office headset system with a telephone interface. It is intended for office headset setups where the telephone connection is part of the working arrangement.
HP lists this cable for the Poly Savi 7310 Office, Savi 7320 Office, Savi 7210 Office and Savi 8210-M Office headsets. This gives the cable a defined role in those systems: linking the headset setup with telephone equipment. It is a focused accessory for these Poly Savi office models, rather than a headset itself.
Use the model reference to identify the cable: 85R57AA. The product is called the Poly Savi Office Telephone Interface Cable by HP, which distinguishes its telephone interface function from other Savi accessories. Its practical purpose is to support a telephone-connected office headset configuration with the listed compatible systems.
