Thanks.
Bridging -- as indicated in earlier mail -- seems to work.

But I don't get any PH_DATA_IND in bchannel.c.
What to look next? Is the current head (of all mISDN, mISDNuser, lcr)
working elsewhere or is it possible that some feature was introduced
that broke something?

(BTW: I've instrumented bchannel.c in bchannel_receive to open a
logfile, and write to it depending on the actions performed, seems it
never sees PH_DATA_IND or DL_DATA_IND, but we *do* see dtmf.)
