Thank you for posting and welcome to the Bose Community! I would love to answer any questions you may have on your headphones.
You can mute the NCH700 by pressing and releasing the Voice Assistant button to mute the microphone. You can see all of the information about the headphones inside the user guide here.
If you have any other questions then please do let us know.

Thank you for posting and updating me on this! Sorry to hear that the mute function didn't work correctly.
When using the headphones with a mobile device are you using Google Assistant? Also can you please attempt to use the headphones with another device and attempt to mute the call and see if you still have the same odd experience.
I look forward to hearing back from you with the results of the questions above.
It is interesting that it is giving the same prompt without the phone connected.
Have we tried muting a call on any other devices, like your phone, as Hector suggested, or have we just been using the laptop so far? As it would be useful to know if this was just limited to the laptop or happening with everything.
One thing that would definitely be worth trying is removing Google assistant with the Bose Music app and attempting to mute the call then, as with no connection to google assistant, there would be no reason for it to prompt us about it. If this works we can re-add it back and see if the issue comes back with it.
Is there any more guidance on this? The guide says that the right bottom button is a mute button when on a call, but invokes the voice assistant when not on a call. Apparently the headphones do not treat streaming a video-conference as "being on a call". So is there another way to mute the microphone when on a video-conference from a computer?

Your Bose needs to be in "Headset" mode for it to mute/unmute rather than using voice assistant. Normally it auto switches when joining a call but you may need to select the headset (not headphones) as your device in Skype etc.
