FOR THE FIELD / START HERE

Better Evidence. Better Voice Decisions.

Start with the question you need to answer: how much capacity to reserve, what the statistics mean, or what to check during an incident.

01 / CAPACITY

Size the voice path

Understand codec rate, packets, overhead, and capacity in each direction.

5 min read 02 / MEASUREMENTS

Read the call statistics

Put latency, jitter, packet loss, and round-trip timing in context.

5 min read 03 / IN THE FIELD

Find the next useful check

A practical sequence for choppy audio, one-way calls, echo, and failed setup.

6 min read 04 / HARDWARE

Choose an endpoint with context

Understand desk phones, DECT handset systems, and USB/Bluetooth headsets with compatibility checks and clearly labeled paid links.

Keep Three Things Separate

A plan: the calculator estimates traffic from explicit inputs. It does not discover your negotiated codec or available capacity.
An observation: measurements belong to an endpoint, direction, path, and time window. Record those before comparing numbers.
A diagnosis: a repeatable comparison and supporting evidence are stronger than one red counter.

Bring Context to a Review

Record whether the call was internal or external, wired or wireless, and affected one user or many. Note the codec, packet interval, approximate call time and time zone, and what changed between good and bad tests. Keep private identifiers in an approved support system, not public screenshots.

Use the call-metrics reviewer for a first interpretation. It is deliberately not a certification tool and does not calculate a MOS score.
