    RTP bridge away with inband DTMF and feature detection
    
    When deciding whether Asterisk was allowed to bridge the call away from the
    core, chan_sip did not take into account the usage of features on dialed
    channels that require monitoring of DTMF on channels utilizing inband DTMF.
    This would cause Asterisk to allow the call to be locally or remotely bridged, 
    preventing access to the data required to detect activations of such features.
