I understand from the param description that it tells how to behave
AFTER rtp proxy has been marked disabled:

  Once an RTP proxy was found unreachable and marked as disabled, the
  rtpengine module will not attempt to establish communication to that
  RTP proxy for rtpengine_disable_tout seconds.

The problem that I have experienced is that it takes long time (2
minutes or so) before rtpengine modules disables a non-responding
rtp proxy.

Also, no matter what the module does, it must not make the whole sip
proxy non-responsive for any number of seconds.
