Mitel 5330 / 5320 wireless hand / head sets not working

Our company just switched over to FreePBX , and once we switched over the wireless hand sets, and head sets, will not connect anymore.

The wireless handsets are not supported in SIP mode, only MiNet, mitel proprietary mode. Not sure about the headsets.

If they used to work but don’t now, that means there should have been a Mitel Channel Driver installed somewhere.

Thank you I will look into these suggestions, and let you know.
