Maybe. Listening to the call setup might be enlightening. It may be that
some mode isn't set the same when calling or the dial string is different
(missing pauses or having different call setup tones).

Even if you got "No Carrier", that possibly could have been after a successful
connection to the remote modem where the other side dropped the connection
for some reason (e.g. authentication failure).

One unlikely issue is problems with call waiting. On our phone network (which
may not be like yours) if you try to disable call waiting when you don't have
call waiting this will mess up the call.

I don't know. I don't know why you have to mess with kppp in any case.
I just set up the dialup setup using the GUI system config tool for networking.
It uses wvdial and pppd underneath, and is easy to use.
