I have a new installation of 7941 phones on CUCM 6.1. Customer is using some Plantronics Headsets (some existing, some new), but none seem to work unless they are plugged into the Handset port of the phone. They then work if the Headset button is pressed. If Headsets are plugged into the Handset port, the Handset does not work.
As far as I know, I don't have to configure anything on the CUCM to enable Headsets.
Has anyone seen this before, or is there something missing?
What model of Plantronics Headset are you using? We have used many corded models like the H-91, H-101, H-171's. The one part you will need which is required for all "corded" Plantronics Headsets (to go from Headset Jack on 7941 to "Quick Disconnect" on Headset) is a special Cord (shown below);
If these are Cordless Headsets like the CS-55 or CS-70 Series make sure you set the Compatibility wheel on the Base Station to #4
