We have an IP Office 412 and our receptionist has 4 lines show up on her phone. Occassionally all four lines fill up and she has to park someone to free up a line so she can place a call. I understood that the fourth line you could use to only make outgoing calls, not receive any for this purpose. Is this something you have to setup? Can I disable incoming calls on the 4th or even 5th line?
