Conferencing audio and video
Review microphone and loudspeaker paths, mute behaviour, echo symptoms, USB device selection and camera or display routing. A local participant and a separate far-end caller may be needed to reproduce the issue and judge the result during a real test call.
DSP, routing and network triage
Inspect available DSP files, channel naming, levels and routing against the room drawings. Check reported device status and network symptoms with customer IT, including relevant Dante, AES67 or AV-over-IP paths. Switch, VLAN and firewall changes require IT approval and a defined change window.
Source-code fixes
Assess control logic, device feedback, startup sequences and reproducible faults in available Crestron, Q-SYS or Biamp Tesira project files. Source availability, tool versions and third-party licences determine what can be edited. A running processor does not by itself establish that editable source is available.
Existing-system assessment
Review the equipment inventory, configuration exports and service history to identify documentation gaps. Where evidence points to cabling, power, damaged hardware or firmware compatibility, record the next physical check or vendor escalation instead of treating every symptom as a programming fault.
