If Tony at extension 1234 CFW his phone to the attendant, so he can work uninterupted in his office (like a do-not-disturb function), that is Tony is still in his office but want's the ATT-operator to screen the calls, and only put through VIP-calls. How can this be done? Tony has a analog set, btw.
