I'm afraid not.

I have no ideas about caller-ID (it's not supported by the Deutsche
Telekom on analog lines).

Well, perhaps give it a try?

I realized this.  But still, you make getty far more complex by adding
this, and in particular, you're pulling an entire new class of
problems into getty in the end: handling the various idiosyncrasies of
various modems.

As long as the regular getty demands an un-broken modem, one that can
remember its speed for an incoming call, and that properly resets on
each DTR drop, things are simple.  Once you start to talk to modems,
look at mgetty for the result.  mgetty wasn't always that fat, but
much of the code has been added to handle any oddball modem that can
be found on this planet.
