About VoIP Cost Guide
VoIP Cost Guide is an independent educational site about two things: what business VoIP actually costs, and how VoIP systems are diagnosed and fixed when they misbehave.
Our Editorial Team
Guides are written and reviewed by the VoIP Cost Guide Editorial Team, working from published standards and professional VoIP practice. The site's technical direction comes from working VoIP engineering experience — the day-to-day world of SIP trunks, hosted PBX deployments, packet captures and call-quality tickets that this site's troubleshooting pillar is built from. Cost content is prepared from published pricing structures, regulator fee schedules and provider documentation, worked into examples any reader can re-run with their own quotes.
We are a guide, not a vendor. The site sells nothing, installs nothing and takes no referral commissions from the providers, carriers or equipment makers mentioned in its pages. Where a brand name appears, it is because the technology or pricing model requires an example, never because of a commercial relationship.
Our methodology
Standards first. Technical claims trace to the documents that define VoIP: RFC 3261 (SIP), RFC 3550 (RTP), RFC 4028 (session timers), ITU-T G.107 (the E-model behind MOS), ITU-T G.114 (delay guidance) and FCC rules for emergency calling and taxes. Each guide links the sources it relies on.
Models, not invented prices. VoIP pricing changes constantly and varies by contract. Rather than publish vendor prices we cannot verify daily, cost guides teach the pricing model — the line items, fee categories and formulas — and work complete examples with clearly labeled sample rates. Where a figure is a matter of public record (a fee schedule, a published list price), the page names the source and the date it was checked.
Symptom-first troubleshooting. Every fix guide starts from what a user experiences, narrows the fault with captures and measurements, and gives steps in the order a professional would try them — cheapest and most likely first. Each guide also states its limit: the point at which the fault belongs to a carrier or a qualified engineer.
Corrections. VoIP changes — codecs evolve, fee schedules update, providers reprice. Pages carry a last-updated stamp, and readers can flag errors through the contact page. Material corrections are made in the page and reflected in its date.
How guides are researched and updated
Every guide begins from a question readers actually ask — a symptom they are hearing, a line on a quote they cannot decode — and is researched against primary sources before a word of advice is written: the RFCs and ITU-T recommendations that define the protocols, FCC publications for fees and emergency-calling rules, and providers' published documentation for pricing structures. Drafts are checked for internal consistency (our budget series uses one set of labeled sample rates throughout, so examples can be compared across pages) and for the discipline described above: models over invented prices, measurements over folklore. Published guides are revisited when the underlying material changes — a fee schedule update, a standards revision, a reader's well-sourced correction — and the last-updated date on each page moves only when the page's content genuinely changes.
Funding and independence
The site is funded by its publisher and, in time, by advertising clearly separated from editorial content. No provider can pay to be covered, ranked, quoted or linked; no guide is sponsored; and the worked examples deliberately use sample rates instead of any vendor's live prices so that no company's current promotion can bend the arithmetic. If that funding model ever changes in a way that touches editorial content, the change will be disclosed on this page first.
What this site is not
It is not a substitute for a qualified engineer working on your system, and nothing here is advice about your specific installation — especially where emergency calling is concerned. Treat the guides as the knowledge base that helps you diagnose common problems, budget honestly, and have precise conversations with providers. The full legal framing is in our disclaimer and terms.
