You're making the further assumption that the network service
administrator at IBM knows or cares that the Cisco website exists,
rather than making a generic configuration that covers all applications
that read getDefaultIceServers.

Furthermore, you're making the assumption that the Google host (who has
to give the URL to the user who's calling in) knows that the user is
currently on the IBM network.

If all those assumptions are true, other solutions work. But I don't
think they will be true in very many cases.
