Correct.

To expand: The documented interface for CAPI 2.0 applications is the shared library libcapi20.so. Originally that library just interfaced to the kernel CAPI subsystem through /dev/capi20. Later it was extended to support different access paths to ISDN devices: - via /dev/capi20 and kernel CAPI as before - over the network and a remote CAPI server running rcapid - over the network to FRITZ!Box router via AVM's CAPI-over-TCP service - last but not least, via the mISDNcapid daemon and mISDN
Of course this cuts off anything that doesn't pass through libcapi20.so, including applications that (against the standard) access /dev/capi20 directly but also the capidrv.ko i4l compatibility shim.
