    SIP Notify via AMI or CLI leaks SIP PVTs
    
    Any SIP notify sent via AMI or CLI leaks a SIP PVT with ref count +2.  Removing
    the additional ref just before the invite and adding an unref following it
    corrects the issue as seen via REF_DEBUG.  The unref existed in a distant
    revision and it appears as though the wrong ref operation was removed.
