docs: This method creates a NOTIFY message using the given parameters and sends it to the subscriber.
  The request will be resent if challenged. Use this method only if you have previously called
  processSubscribe(). Use this method if you don't care about checking the response to the sent
  NOTIFY, otherwise use sendStatefulNotify().
  
  @param subscriptionState - String to use as the subscription state.
  @param termReason - used only when subscriptionState = TERMINATED.
  @param body - NOTIFY body to put in the message
  @param timeLeft - expiry in seconds to put in the NOTIFY message (used only when
  subscriptionState = ACTIVE or PENDING).
  @param viaProxy If true, send the message to the proxy. In this case a Route header will be
  added. Else send the message as is.
  @return true if successful, false otherwise (call getErrorMessage() for details).
