Description

It seems possible that something broke something relatively recently.

I say that because I had a working system up until doing an apt upgrade with osmocom nightly.

With current nightly, all calls fail with this distinctive error in osmo-bsc:

abis_rsl.c:982 lchan(0-0-7-TCH_F-0)[0x55753645df50]{ESTABLISHED}: (type=TCH_F) CONNECTION FAIL (cause=Remote Transcoder Failure [ 28 ])

I connected the DUG/RUS to an older system and the error did not occur.

I tried to a small extent dissecting osmo-bsc but I couldn't find it. Which makes me think whatever broke is maybe not in osmo-bsc
I copied all the osmo- binaries from the working system and still get the error!!

So ..Something in libosmocore/abis? Anyway, I'm exhausted with this and need to take a break, so Sorry it's not a better bug report.

See packet number 582 in the pcap.
