The GNSO uses the same teleconference facility. I would guess that
the GNSO e-mails include specific times because the GNSO staff put
them there, not because of the service provider. The GNSO conferences
work relatively well most of the time, and with FAR more people
participating. I suspect that part of the issue is that we have more
people from "unusual" locations which require call-outs (and
seemingly no mechanism to know that they have dropped and need to be
re-called).

I think that we should outlaw the use of Skype and equivalent, and
strongly discourage mobile phones unless absolutely necessary.
