I would hazard that it is the port number of '0' that is causing the
problem. It should not be necessary, but have you tried

  Dial(SIP/4009 at 10.0.0.22:5060)

To see if it helps. If so, it is probably symptomatic of a config
error elsewhere. I seem to remember seeing reference to a similar
problem on the list a couple of months back, but did not find it with
a cursory search.
