In order to display the response on the handset, Cisco phones require
that you have privileges and CTI control over the phones.  The only
un-authenticated things you can display through the phones are through
the services and directories keys.  Unfortunately, they are keeping that
locked up since they want you to use them with their system.  Hopefully
they will change their minds one day.
