A group I'm part of has been using Google Meet for our audio conferencing. I'm quite unhappy with it. There is too much lag and too much noise when someone is moving around (squeaky chair, noisy snack, etc.). Also, sometimes there is an echo of my voice, and sometimes there are gaps in someone's speech.
I would like to dial in on my landline phone. I use a Windows desktop computer but others may use other operating systems.
I would prefer something free but a reasonable price would be okay too.
I've never seen more than 10 people attend on a given day.
