Hi Andreas,
I think it is best if you wold reach out to netdev and/or Arndt Bergmann
yourself.
I think the main problem they are trying to solve is that nboody seems to be
maintaining mISDN anymore. If I remember correctly it was stated that Karsten
Keil is not acive anymore, for example.
If there still are users out there, it should be brought to the attention of
netdev folks.
Regards,
Harald

Hi Harald,
I don't see why mISDN should be removed from Kernel. Beside talking to TDM
based GSM equipment, it can be used to connect ISDN phones and gateways to
make regular phone calls.
I use 'osmo-cc-misdn-endpoint' in conjunction with 'osmo-cc-sip-endpoint'
as
a new gateway application to replace LCR.
(
https://osmocom.org/projects/osmo-cc) And there are other users that have
some kind of gateway setup to interconnect their ISDN equipment to SIP. Some
of them use LCR, a few others use osmo-cc-*-endpoints.
If there is trouble with current kernel API, I would help to fix it. Feel
free to forward my opinion to netdev and Arndt Bergmann.
Best regards,
Andreas
