Actually, B is necessary first to enable voice features on the router before you can configure SIP registration with C or D. You can’t jump straight to registration commands without enabling voice service.

C/D? C sets the global parameters for SIP phone registration, while D configures each phone’s directory number. The question seems to focus on registration, so C is a solid choice here.

It’s B. voice service voip is needed first to enable SIP features; without it, you can’t really start any SIP phone registration commands like voice register global. So it's the proper starting point.

I’m with C here since voice register global is the actual command that kicks off SIP phone registration setup. The others are either too general or about different parts of the config. C

C imo, you need voice register global to start configuring SIP phone registration. But honestly, the explanation I saw didn’t really explain why the others are less relevant. Anyone else got a clearer breakdown?
