Difference between hardphone and softphone registration?

• A. Hardphones are physical endpoints; softphones are applications registering via client software
• B. Softphones are physical endpoints
• C. Hardphones register via client software
• D. Hardphones require more bandwidth

Answer: (A)

Registration is how an endpoint proves its identity to the call-control server so it can receive calls. A hardphone is a physical IP phone; its registration happens as a dedicated device with its own built-in endpoint profile on the call-control system. A softphone is software running on a computer, tablet, or smartphone; it registers as a client application under a user account. Both register with the same call-control platform (often via SIP), but the difference is what’s registering: a physical hardware device versus a software client. Bandwidth isn’t the defining factor here; the key is the endpoint type and how it authenticates to the server.
