| 3900's and Headsets I recently just bought the 3904's. I like them. I have seen two different versions of the 3904. One has three spots to plug in a handset, headset and line cord. The other version, has only the handset and line cord connectors. If your 3904 has the three spots, try plugging your headset into the handset spot. Not sure if this will work, or if you already tried. Thought it may be worth a shot. Good luck! I'll ask a vendor that I'm meeting this afternoon on the 3904's. Maybe she will know. If so, I'll post back to you tomorrow. |
