      <li>Summary</li>
          <ul style="list-style: none;"><li>As a developer I want the provisioner to return NULL for any unconfigured combo or feature keys in SmartPBX so that we know to remove the parameter in provisioner</li></ul>
      <li>Description</li>
          <ul style="list-style: none;"><li>In SmartPBX setting a device feature key or combo key to &#039;none&#039; should result in a NULL payload for that parameter.  That will cause the provisioner to remove the setting.
  Additionally, Kazoo will NOT store the NULL so it should not be expected to be seen on subsequent get requests.</li></ul>
