Plantronics, Sennheiser and Jabra have wireless headsets for a 3com phone.
If you wish to roam around the office while using the wireless headset you'll need to get the remote lifter* accessory.
* For Jabra wireless it is the GN1000
* For Plantronics it is the HL-10 .
Below is a video demonstration of how a remote lifter is used with your 3com telephone.
