Are the GN9125 and GN9330e both compatible with the Cisco SPA504?
Both the Jabra 9125 series and 9330e are compatible with Cisco SPA504 telephones. There two things to keep in mind when using wireless headsets with this Cisco telephone.
- Any wireless headset that you will connect to this phone's headset jack requires the 2.5mm connector cable.
- If you plan to roam around the office and be able to pickup/hangup from the headset you will also need the GN1000 lifter.
Below is a video demonstration on how to use the GN1000 remote lifter.
