did harald change the bit order on the controller? there is a flag for that. you can patch the hfcmulti.c. maybe harald did that but forgot to put it into the kernel patch. i will also provide patch to openbsc to automatically consider that bit order in conjunction with misdn interface.

I can only talk for my "personal" Windows driver, for me the changed
bit order works. I just wonder why mISDN and the HFC-E1 works different
on Haralds PC than on others.

For a Full Rate Codec (should work too, however OpenBSC has to
modified so that "Full Rate" is used by the phones too) you can
use Toast (http://kbs.cs.tu-berlin.de/~jutta/toast.html).

Best regards,
