Improving dial-in experience

Hi all,
I wanted to ask for a volunteer to look into improving our collective
dial-in experience on the Tuesday calls. The concerns:
- phone line has limited number of connections, and costs money for Digital
Bazaar. We'd like to avoid this.
- linphone: variety of issues -- possibly just user experience, but not
working for a number of us: dropped connections, inability to use

 This could be resolved by suggestions for, per David's request,
"idiot-proof" sip clients. Can anyone volunteer to look into this? I
personally stopped using Linphone due to dropped connections and haven't
had time to follow up.

Thanks!!
Kim
