Hi, I have a system with a user on a M7310 with a Plantronics headset with a quick disconnect cord. The handset will not work unless the headset is fully unplugged from the phone. The quick disconnect does not work. There is a T series phone on the same system and I tried it there, it works 100% fine and the handset works with the headset still connected and working.
Any ideas?
