preferred method of setting up dialup

[David Williamson]

Trying to set up a dialup connection, I can create the connection using
the network-admin utility, and can connect and disconnect using that
utility.  But I recall discussion on the list of wvdial or some other
dialer - and wvdial needs additional configuration, evidently.  ppconfig
works too, but then requires, evidently, that I create a dip group.
What's the preferred way to do things in Ubuntu for dialup?

Thanks -
