14 is already implemented while the other is in the plans: 14 Both of these libraries are used by themwi-mgw as mandatory dependencies.

16 2a) libgsmfrp is the Rx DTX handler for the original FR codec, a front-end
17 preprocessor that sits in front of libgsm decoder. This preprocessor
18 implements functions specified in GSM 06.11, 06.12 and 06.13, and these
19 functions are required (not optional) for a network-side implementation of
20 GSM FR codec in a TRAU-like component.

22 2b) libgsmefr will be a librified (turned into a library) version of the
23 official reference implementation (from ETSI) of GSM EFR codec.
