What video conferencing do law firms need?

Law firm video conferencing has to do three things general corporate VC doesn't: protect privileged conversations from third-party transcription bots, hold an explicit recording governance policy that SRA-regulated supervisors can defend, and integrate with the firm's own data loss prevention and retention controls. The hardware choices fall out of those three constraints, not the other way round.

The headline trade-off is native versus BYOD. Native rooms (Microsoft Teams Rooms, Zoom Rooms, Cisco Webex Rooms) deliver one-touch join, in-tenant recording and consistent telemetry, which matter for partner offices and boardrooms where the calling pattern is predictable. BYOD rooms with a single platform-agnostic VC bar handle client meeting rooms and matter rooms where the other side might be on Teams, Zoom, Webex or Google Meet on any given day. Most firms run a mixed estate: native in partner offices and the boardroom, BYOD in client-facing rooms.

The decision that usually surprises buyers from outside legal is AI transcription policy. Third-party transcription tools that join via "ghost participant" (Otter, Fireflies, Read, Granola and similar) take privileged client conversations off the firm's network and into a third-party tenant the firm has no contract with. Most magic circle and silver circle firms now either block these at the network layer or restrict transcription to in-tenant tooling: Microsoft Teams Premium, Cisco Webex AI Assistant or Zoom AI Companion, where the data stays inside the firm's own M365, Webex Control Hub or Zoom tenant and the existing DLP, retention and legal-hold rules apply. We document this position as part of the legal sector AV design phase rather than leaving it to IT to retrofit.

Hybrid hearing rooms and arbitration suites sit in a separate category. They need court-recognised platform compatibility (the Cloud Video Platform for Crown Court, party-appropriate platforms for arbitration), multi-camera coverage of bench, counsel and witness, court-grade audio capture into a Q-SYS or Biamp DSP, and a recording chain that integrates with the case management system. Specifying this against the right video conferencing platform stack is significantly harder than a standard meeting room and benefits from a sector-specialist design phase.

Quick reference: native MTR/Webex/Zoom Rooms in partner offices and boardrooms, platform-agnostic BYOD bar in client and matter rooms, third-party transcription bots blocked or restricted to in-tenant Teams Premium / Webex AI Assistant / Zoom AI Companion, hybrid hearing rooms separately specified for CVP and multi-camera capture.
