phone callers can't unmute
the *6 seems to not be working for them. I've tried it myself and I am getting the same result.
An update, we think we have identified the issue. Once "Mute Everybody" is enabled those who haven't joined the call yet will enter muted, and *6 will not work. As a workaround, you can wait to use the "mute everyone" function until everyone has joined the call. They should then be able to mute/unmute using *6.
I realize this is not an ideal solution, this has been reported to the team for review, and I will update the thread on progress. Thanks for your report and time.
