Just checked the logs, thanks. So... ModemManager doesn't support Infineon chipsets yet :-/ The call setup fails in the last step:
(ttyACM0): --> 'ATD*99***1#<CR>'
(ttyACM0): <-- '<CR><LF>+CME ERROR: 4<CR><LF>'
It's probably not hard to fix, though. A new plugin to handle the Infineon-specific call setup would be needed.
Beers for anyone willing to sponsor a device of this kind for MM developers; and extra beers if you just write the plugin yourself :-)
