Why we don't resell carrier minutes — and why you shouldn't pay anyone who does

Aircall and JustCall mark up Twilio rates 3–5×. We pass Telnyx and DIDLogic rates through verbatim. Here's the math, the architecture, and the hidden cost you're paying.

Why we don't resell carrier minutes — and why you shouldn't pay anyone who does

The markup problem

Aircall, JustCall, and most "modern" calling tools resell Twilio (or a carrier like it) under their own brand. You pay a per-seat fee plus a per-minute rate — and that per-minute rate is typically 3–5× what they hand Twilio. The gap is their margin, dressed up as your bill.

Run the numbers on a 50-agent outbound team doing 200 dials/day at a 90-second average:

  • 50 agents × 200 dials × 90s = 250,000 minutes/month
  • At Twilio's actual rate (~₹0.85/min for India outbound): ₹212,500/month
  • At Aircall's resale rate (~₹3.50/min for the same): ₹875,000/month
  • Markup tax: ₹662,500/month — ₹79.5L/year

Add the per-seat fee (~₹2,400/seat/month × 50 seats = ₹14.4L/year) and you're at ~₹94L/year for 50 seats — ~₹79L of it pure markup you'd never pay the carrier directly.

The "bring your own carrier" alternative

The Autocloz model is the opposite: you sign up directly with whatever carrier you want. They bill you. We never touch a rupee of your call spend — we charge one flat platform fee per workspace.

Same 50-agent team, run our way:

  • Telnyx India outbound at ₹0.85/min × 250K min = ₹212,500/month
  • Autocloz Business tier: ~₹40,000/month
  • Total: ₹252,500/month — vs. ₹781,000/month with Aircall (~3× cheaper)

And it compounds. The platform fee stays flat no matter how much you dial, while carrier rates *drop* as your volume climbs — Telnyx and DIDLogic both cut volume discounts that land in your account, not ours.

"But isn't BYO complex?"

The resale pitch leans on one claim: BYO is operationally hard — set up the carrier account, configure SIP, manage DIDs, and so on. That was true back when Twilio's API was raw. It stopped being true.

Telnyx onboarding today: paste an API key and a connection ID into Autocloz Voice Settings. Done. DIDLogic is the same; FreJun is per-agent OAuth. We handle the dial endpoint, recording, webhook signature, and IVR runtime — every layer that used to justify a wrapping vendor.

The hidden cost: your data lives somewhere

Pay Aircall and your recordings sit in Aircall's S3, your CDR in Aircall's database, your IVR config in Aircall's UI. Churn, and you walk out with a CSV export — and every recording URL breaks behind you.

BYO Telnyx and your recordings live in your Telnyx account, your CDR in your Autocloz workspace's Postgres. Cancel Autocloz tomorrow and your data still sits in two places you control.

The gotcha: your compliance is yours

Here's the flip side, and it's real: BYO carrier means the compliance burden — TCPA, India DLT, STIR/SHAKEN — is yours, not the vendor's. Autocloz enforces it at the dial gate (DNC pre-flight, country quiet hours, DLT registration check), but filing the registration with TRAI or the FCC is on you. Most teams finish it in a week with their lawyer; some pay a consultancy a one-time ~₹50K.

Call it what it is: a real cost. It's still ~25× cheaper than paying the markup tax forever.
