Network readiness and priority
Real-time traffic carries latency, jitter and loss targets distinct from everything else. Priority policy has to hold end to end; priority missing at a single hop is as good as no priority at all.
- Latency, jitter and loss targets are written separately
- Priority marking is preserved end to end
- Branch links reserve a capacity margin
- Priority is tuned separately on the wireless side
Meeting room and device design
Room acoustics and microphone placement are the real source of most quality complaints. Devices are selected to room size; a single standard build wastes money in a small room and underperforms in a large one.
- Device selection is tiered by room size
- Acoustic treatment precedes device choice
- Starting a meeting takes one step on entering the room
- Remote and in-room participants get comparable experience
Numbering plan and continuity
Voice is the organization's most visible outward channel, and its outage shows immediately. Numbering plan, routing rules and trunk redundancy are designed together, and emergency call behavior is tested separately.
- The numbering plan is built with growth in mind
- Trunk redundancy and automatic rerouting are defined
- Emergency call behavior is tested together with location
- Where recording is required, retention is written down
Experience measurement
Quality is managed by measurement rather than by complaint. Call and meeting quality indicators are collected; problem rooms, branches and trunks are listed by name so remediation goes to the right place.
- Measurement surfaces problems before users report them
- Repeated poor experience for one user is counted separately
- Records cover at least one full working week
- Device, network and client data align on one timeline
