Night highway from a truck cab — the road RubyVox answers calls for

Voice gateway

RubyVox answers the phone so dispatch doesn't have to.

Check calls, facility details, detention intake and pay questions — handled around the clock, with every money move still gated by policy.

Authentication and call state

Signatures are verified before any context is loaded; timestamps outside a five-minute window and replayed event IDs are rejected.

signed_message = telnyx_timestamp + ":" + raw_request_body
valid = Ed25519.Verify(
  Telnyx-Signature-Ed25519, signed_message, TELNYX_PUBLIC_KEY)

Action allowlist

What the agent may request, what commits automatically, and what escalates to a human.

Action	Auto-allow when	Escalate when
Provide shipment status	Caller authenticated; customer-safe facts only	Low location confidence or active incident
Record carrier availability	Approved contact with a valid carrier profile	Identity mismatch
Record tender acceptance	Insurance, authority, equipment, rate and contact all match	Any exception
Record ETA	Driver or carrier link verified	Material GPS/ELD conflict
Confirm appointment	Facility record and contact match	New cost or rejection outside policy
Create recovery request	Active incident and evidence threshold met	Tier 0 cargo, safety or custody issue
Activate vendor	Pre-approved vendor, playbook and budget threshold	Over budget or non-approved vendor

Never permitted

Changing banking details, releasing payment, overriding a fraud hold, promising coverage or payout, or authorising air charter. These route to finance, compliance and legal workflows only.

Incident mode and resilience targets

Severity runs 1 (single delay) to 5 (multi-region catastrophe). Campaigns stop the moment capacity is secured and never negotiate beyond ceilings.
