enterprise networks are switched, so the connection from the desk goes to a
switch and then right to the VoIP system, so it’s basically non-trivial
to tap a phone line that way. VoWiFi is different, but there are more issues than
security with that. Legacy environment equivalent for wired VoIP.<o:p></o:p></span></font></p>
