    Inband DTMF regression
    
    The functionality of inband DTMF in chan_sip relied upon
    ast_rtp_instance_dtmf_mode_get/set not working properly to avoid calling
    ast_rtp_instance_dtmf_begin/end on RTP streams with inband DTMF. According to
    documentation, ast_rtp_instance_dtmf_begin/end is meant only for RFC2833 DTMF,
    never inband.  This fixes the regression introduced in revision 328823.
