PS1: Disclaimer: I currently have no way to test any CSD functionality or anything else that requires osmo-bts-trx; this patch has been implemented "from theory only". However, the current code is known to be wrong (E2 is always 0), whereas the new code stands at least a chance of being correct. In any case, I would appreciate it if someone can test it. If someone can run a test setup and send me pcap of the RTP output, I can analyze that pcap myself to verify correctness of E-bits.
