Description

The GSM 05.03 implementation present in libosmocoding is using the RTP speech frame format for TCH coding functions. It is implemented in a way of performing 'canonical -> RTP' bit reordering in decoding functions, and 'RTP -> canonical' bit reordering in encoding functions. At the moment, the RTP format bit reordering implementation is not exposed.

This API could be used by some other projects (at least by osmo-gapk), moreover libosmocoding is already being linked against libosmocodec.
