However, it does not seem to work for line 1 either, therefore it might also
be a limitation by the provider.

By the way, how can I unregister/cancel diverts on the second line?
There does not seem to be a CancelDivert method, and the method DivertCancel
does not accept basic service numbers as arguments (at least, I couldn't
