Get in Touch with CallTypes
CallTypes is a small, independent site, so contact goes straight to the person who runs it — there’s no support queue or ticketing system behind this address.
admin@calltypes.com. We read everything; there’s no guaranteed response time, but a clear subject line and specifics help a reply come faster.
What’s useful to include
- A calculator looks wrong: name the tool (e.g. the Call Quality Score Calculator) and the inputs you used, so the result can be reproduced.
- A formula or method question:tell us which tool and which number you’re unsure about — Erlang C on the wait-time and staffing calculators, or the ITU-T G.107 E-model on the quality-score tool.
- Something’s broken: your browser, device, and the steps that led to it help most.
- A tool idea:tell us the telecom or business-comms problem you’re trying to solve.
Before you write in
Check whether the blog or learnsection already answers your question. And a reminder on scope: every calculator here gives an estimate from the numbers you enter, not professional telecom-engineering, financial, or regulatory advice — for anything that affects a bill, a contract, or a live network, verify against your carrier and your own testing.
