Connect your switch or SMSC to 6X Route Inspector and audit a route you're buying from any vendor — real FAS detection, CLI verification, and a shareable 0-100 route score. 6X never needs to know who your vendor is.
Point your switch (voice) or SMSC (SMS) at 6X — your real traffic and vendor relationships never change.
6X originates a real call or message through your switch, out via the vendor route you want audited — one-off, batched across several destinations, or on a recurring schedule.
FAS, CLI, and delivery signals combine into a 0-100 score with a shareable report — proof either way.

Detect FAS, CLI stripping, or a route that doesn't match what your vendor's rate card promised — with real evidence, not a guess.
A route that scores well is a real, independently-verified signal you can show your own customers — not just your word for it.
Every test produces a shareable report link — or a one-click PDF, when an email attachment works better than a link for raising a real problem.
Check any route for False Answer Supervision in seconds using a number regulators reserve for fictional use — no destination DID to buy, works instantly for any country.
Real call origination with FAS/CLI/PDD detection, and real SMS delivery-receipt verification — not simulated results.
6X never needs to know who you're buying from — you route the test through whichever vendor you're auditing yourself.
A real report link for every test — usable as evidence with your vendor, or as marketing proof to your own customers.
A real 30-day free trial, instant access, no approval wait — see a real score before you commit to anything.
The FAS Probe mode dials a number regulators reserve for fictional use — check for False Answer Supervision on any route instantly, no destination DID to buy or manage.
Schedule a route to retest itself daily or weekly, with an automatic alert the moment a previously-healthy route degrades — not just a one-off snapshot.
Every completed test and every monitoring alert fires a real-time webhook — build automated route health checks into your own systems, not a dashboard you have to remember to check.
Every report includes a plain-English summary of what happened and why — useful for a non-technical stakeholder reading a vendor dispute, not just raw signaling data.
Every voice test captures a real MOS score from the actual received audio — not just "did it connect," but how it sounded, tag the vendor you're testing so results build a real quality track record over time.
Paste in what your vendor's invoice claimed — for voice or SMS — and Route Inspector compares it against what it independently measured. Catches over-billing, calls billed despite never connecting, and messages billed despite never delivering. Paste in several invoice lines at once for a bulk comparison.
Flat, transparent billing — unlimited tests, no per-test metering, no long-term contract.
30 days, full access to voice and SMS testing, no credit card required.

No. You connect your own switch (or SMSC) to 6X purely for testing — your real traffic keeps flowing through whichever vendor you already use. 6X never needs to know who that vendor is.
FAS (False Answer Supervision), CLI integrity (whether your caller ID survives a route unaltered), real SIP response codes, post-dial delay, and real MOS voice-quality scoring for voice, plus delivery receipts for SMS — combined into one 0-100 route score.
Yes — every new account gets an instant free trial, no credit card required, no approval wait.
Yes — every test produces a shareable report link, usable as evidence in a dispute with your vendor, or to show your own customers a route checked out clean.
No — the FAS Probe test mode dials a number a national regulator officially reserves for fictional/non-working use, so you can check for False Answer Supervision on any route instantly, with no destination DID to buy or manage. CLI verification still needs a real receiving destination, since that genuinely requires observing what arrives on the other end.
Yes — schedule a route to retest itself daily or weekly. If a previously-healthy route degrades, you get an automatic alert (webhook and email) instead of finding out from a customer complaint.
Yes — every report has a one-click PDF download alongside the live share link, ready to attach directly to an email when a link isn't the right format for a vendor dispute.
Yes — paste in what your vendor's own invoice or CDR claimed for a completed call, and Route Inspector compares it against what it independently measured. This catches real over-billing, and the classic case of being billed for a call that never actually connected.
