Sadly the 7911 Series does not have Speakerphone or "built-in" Headset capabilities. There is a Speaker (for on-hook dialing) but no Micrphone :(
Because the 7911G does not have built-in headset capabilities (no headset amplifier or headset button) like the 794x/796x/797x series, the handset must be off hook to connect the audio stream.
For the 7911 you will need to use the setup with the Plantronics M12- Amplifier Kit and chosen headset. For models like the 7911 the M12 has to plug into the Handset Jack and then the Handset Cord plugs into the M12. If you must use the M12 you may need to adjust the Phone/Compatability setting slide (located under door on Left-Hand side of the M12).
