Avaya J100 series IP phones (e.g., J169, J179) use SIP and require an HTTP/HTTPS server to download firmware and configuration files during registration (Option C). This can be hosted on the IP Office system or an external server. Options A and B are control units that support the phones but aren’t the specific requirement. Option D (Voicemail Pro) is unrelated to phone registration.References: Avaya IP Office J100 Series Configuration Guide.
