Does FreeSWITCH support WAV files with GSM 6.10 encoded audio? If not, how hard would it be to implement that? I had a look at the source and it seems that libsndfile already has support for it, I just didn't figure out which steps I'd have to go through to add this to FreeSWITCH. P.S.: Yes, I've tried recording raw .gsm files, but I don't know how I can play them without converting. -- Humberto Diógenes
