Hi Rob,Using a GN Netcom headset with a 8800-00-20 quick connect lead to the phone. No amplifier beign used but I have tried my GN Netcom - GN8000 MPA-UK amplifier, still no volume.Is Plantronics the only headset useable with the 7941? Also this part...

Hi,I also have one of the 7941G phones.Boot load ID: 7941G_64-02070631Amd64megRel.bin.The headset volume is very low, the volume control on the front does adjust lower to silent but the volume is way to low for normal office use, even a quiet office!...
