Technology Services have tested a wide variety of Corded Headsets in existing use and all types that connect using an RJ9 plug were fully functional.
Most corded headsets have what is referred to as a "quick break" cord. The bottom half of which is pictured to the right with the clear plastic RJ9 connector and the broad flat connection to the cord connecting the headset.
When purchasing your headset you will also need to purchase this separately supplied cable.
Please speak to the supplier about selecting the correct compatible cord. If they are not familiar with Huawei brand phones tell them it has an RJ9 port and Grandstream solutions have proven to be fully compatible.
The recommended combination is Plantronics HW510 EncorePro Corded Headset with a Plantronics Reverse Polaris Cable U10P-S.
