VOIP SOC SYSTEM REQUIREMENTS MATRIX
Use to review a complete proposed product. This is not a chip purchasing ranking.
For every requirement record: target, responsible block, evidence, owner, result.

Product: handset, analog gateway, ONU or other?
SoC / revision / board / SDK / operating system / lifecycle date:
External memory, radio, analog interface and network components:
CPU, DSP or accelerator responsibilities:
Simultaneous calls / voice format / packet interval:
Echo-processing and encryption requirements:
Concurrent networking and management workload:
Measured memory, thermal and performance conditions:
Power by state: idle, active call(s), radio/display, ringing or charging:
Distinguish chip, board and whole-device measurements; record units and method.
SDK/driver/voice-stack supplier and access conditions:
License obligations / errata / support period / escalation:
Authenticated update process / key owner / configuration persistence:
Interrupted-update recovery / test result:
Open issues, evidence required and release owner:

FICTIONAL ACCEPTANCE EXAMPLE
A gateway needs two simultaneous calls plus normal network traffic and remote
management. Record the exact line circuit, memory, voice software and test
conditions. A one-channel idle demonstration leaves the full requirement open.
Ask for evidence under the specified combined workload.

REVIEW RULES
A feature list establishes claimed functions, not whole-product performance.
Secure boot is one requirement; update delivery, key management, vulnerability
response and support ownership need their own evidence. Revisit after platform,
software, lifecycle or external-component changes.
