You mean the local end release being broken in the

this out? I see your point, that the release command has been sent,
but we never got any ACK or something like that back. But how is it
possible that it works for SAPI=0 and it does not for SAPI=3 ? These
units were used by big organizations to improve the indoor coverage, I
really don't think that the BTS or its firmware is wrong by design.
Maybe OpenBSC destroys SAPI=0 too fast, and there is not enough time
for this:
Check rsl_release_sapis_from and the caller in _lchan_handle_release.
First everything from 1 t X is released and the SACCH deactivated.
Play with that, or attempt to get a trace of a Nokia BTS with a Nokia
BSC and look at there release procedure. E.g. if order or release
requests kinds are different.
