Remote commissioning requires an on-site technician who can identify devices, operate controls and listen in the room. Together we check microphone pickup, playback levels, loudspeaker output, routing and mute behaviour. For conferencing, the checklist includes far-end listening, echo symptoms and simultaneous speech under representative room conditions.
AEC configuration depends on the signal paths and what the microphones hear in the space. Software changes cannot establish whether a cable is miswired or a loudspeaker is physically obstructed. Microphone placement, room acoustics and background noise may need physical correction. These findings are recorded with the responsible party and follow-up check.
Acceptance criteria and the available measurement or listening checks are agreed beforehand. When hardware, access or a far-end test participant is unavailable, the corresponding check remains open. The handover identifies what was verified and what still requires a site visit or a coordinated test.
