osmo_rtp2trau() for FR & EFR: correctly handle the no-data case 3GPP TS 48.060 sections 6.5.2 and 6.5.3 prescribe the behavior of TRAU frame emitters under conditions of not having any speech or SID frame to send. In the case of osmo_rtp2trau() this no-data condition is indicated with a zero rtp_len argument to the function, but this case was not handled correctly: a garbage speech frame (previous buffer content for the D bits in struct osmo_trau_frame) was being generated. The present change implements the rules of TS 48.060 sections 6.5.2 and 6.5.3: standard FR/EFR speech frame with BFI=1 for UL, special idle speech frame pattern for DL.

This repository contains a set of C-language libraries that form the A-bis interface library of Osmocom Open Source Mobile Communications projects such as OpenBSC / OsmoBSC.
Historically, a lot of this code was developed as part of the OpenBSC project, but which are of a more generic nature and thus useful to (at least) other programs that we develop in the sphere of Free Software / Open Source mobile communications.
The libosmo-abis.git repository build multiple libraries:
The official homepage of the project is https://osmocom.org/projects/libosmo-abis
You can clone from the official libosmo-abis.git repository using
git clone https://gitea.osmocom.org/osmocom/libosmo-abis
There is a web interface at https://gitea.osmocom.org/osmocom/libosmo-abis
There is no Doxygen-generated API documentation yet for this library. It would be great to some day have it, comparable to libosmocore.
