OK, this is making more sense, Thanks for the drawing, so in our case we have CenturyLink as the provider in the security office, what is the interface there ,or would there be a direct line to the gate keypad? If so I would assume that that keypad would have its number, correct?
Are you actually saying that you don't understand that the gate controller and call box at the gate are connected to a phone line??
1) Visitor enters the directory code for the resident they want to visit.
2)The call box calls the resident using it's own phone line.
3) Resident answers the call and can converse with the visitor.
3) Resident dials #9 to open the gate.
Geeze! This ain't rocket surgery!
