  AIX
  
  ****************************************************************
  PROBLEM SUMMARY:
  Potential AIX crash when reading last RTP packet of a call
  once the call has actually been terminated. The vnaio driver
  will attempt to do a read on a blocking socket in an
  interrupt handler which is not allowed.
  

Problem conclusion

• Changed code to ensure bound but unconnected sockets are still
  setup as non blocking.
