audio/opencore-amr is no longer used by sox or imagination. The only remaining use is by telephony/pjsua (no maintainer) - do other pjsua users actually use AMR? I have never seen it used.
If we drop opencore-amr from pjsua (pending), we can drop opencore-amr altogether. I originally imported it to have it in SoX, because my android recorded AMR by default back then. Tha't no longer true, and the whole codec is imho outdated by now, beside being encumbered by patents.
