Hi, To change this, it can only be done by reverting back ticket 658 modification, i.e: changeset 2342 (http://trac.pjsip.org/repos/changeset/2342). I'm not really sure which behaviour is appropriate, however it seems that the ITU recommendation says that the input should be 14-bit. Any feedback/clarification would be great.
