Description
For some reason current version of osmo-bsc keeps getting RLL_REL_IND message after rf channel release when servicing nanoBTS, causing calls to fail a few seconds after connection.

I'ven't looked into the problem if the REL IND is wrong at this time.
But the call release looks good. First the Call is terminated by a CC (Call Control) and afterwards the RR Channel is released.
The call seems to get through (Call Connect) and is terminated by the BSC (frame 1272) (Call Disconnect). Maybe the MSC hang up? The pcap doesn't contain the BSC<>MSC traffic.

- File callfail2.pcap callfail2.pcap added
attached is a pcap file of bsc-msc traffic. Often the call ends with radio interface failure, UE displays "network is busy" message.
