The headset port on Huawei phones is an "RJ9" plug (standard phone handset jack).
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.
If your existing headset does not have an RJ9 connection it may be possible to source only the bottom half of the cord to convert your corded headset to work with your new phone.
The two wireless headsets that are currently recommended for use with the Huawei phones are:
These have been fully tested and are certified by Huawei to work completely with the phones.
You will also need to buy a specific cable with this headset to ensure functionality, the cable is the APD-80.
No "lifter" is required.
These can be purchased through Staples or Eurocom.
For those with other models of existing wireless headsets eg Jabra
Technology Services is working with Huawei and Jabra to develop and obtain a cable that will allow these headsets to work with complete functionality.
There is a cable (14201-33 Link) available that enables most functionality, however the button on the headset allowing calls to be answered directly from the headset does not function, you have to press the Headset button on the phone.
