One important component of Themyscira Wireless system sw, specifically themwi-mgw, implements speech transcoding between GSM codecs on the inside and G.711 on the outside. This essential function creates a dependency on some specialized libraries that implement the codecs which need to be supported. The following codec libraries are currently required: 1) libgsm, the original GSM 06.10 implementation from 1990s; 2) gsm-codec-lib developed by Mother Mychaela for Themyscira Wireless: https://www.freecalypso.org/hg/gsm-codec-lib/ This gsm-codec-lib collection provides two libraries: libgsmefr and libgsmfrp. Both of these libraries are used by themwi-mgw as mandatory dependencies.
