I can definitely leave out the last patch from the series if we know
that there are
still users on CMTP. I searched around for a bit but could not find
any indication
what this is still used for, if anything.

What I found were a couple of references of the driver no longer working
about 10 years ago:

https://wiki.ubuntuusers.de/Archiv/Bluetooth/BlueFritz%21/
https://www.opensuse-forum.de/thread/2776-erledigt-suse-11-2-und-bluefritz/

Is anyone using cmtp for voice or fax services? The use cases from before 2009
that I could find were usually dial-up networking, but that seems pointless now
if the only way to get an ISDN connection is to have it routed over
the internet.

What am I missing?
