During the middle of a conversation, is it possible to press any
buttons on the phone to increase or decrease the volume.
The above applies to one user who has a slight hearing impairment.
So I don’t want to do this on system wide basis.
But I would like to do this on any phone, as needed.
i would think this would be more a feature of the phone rather than asterisk…i understand what you are asking, but i highly doubt asterisk can do it (unless it’s a meetme room) and i’m not even sure it’s appropriate.
if you use headsets, there are some specifically designed for those individuals that are hard-of-hearing - perhaps one of those might work well?
