The problem·03 issues

Voice infrastructure shouldn't be this opaque.

The hidden tax of legacy voice — and why building on top of it bleeds margin every day.

No. 01Peak-hour shock

Premium-route sticker shock

You priced a US-domestic call at $0.0085. The invoice landed at $0.014 because traffic took a route nobody told you about. Your CFO wants a model. The model assumes one rate.

$0.0055
hidden per minute on Twilio
No. 02Verb gaps

Verbs you can't reach

Production wants per-participant broadcast. The SDK exposes mute and nothing else. Now you're patching TwiML strings in your handler. The carrier itself supports the verb — but you can't.

12 verbs
missing through Twilio's surface
No. 03Quiet drift

Reconciliation drift

Carrier CDR says 1.84 minutes. Your invoice says 1.92. Multiply by ten thousand calls and the gap funds someone's quarter — not yours. You want to SELECT * from that drift. You can't.

Migration

Migrating from Twilio? Change two imports.

Same surface for the things that matter — dial, hangup, gather, record. We expose call control directly via REST, not XML markup.

Twilio
before.ts
import twilio from 'twilio'

const client = twilio(SID, TOKEN)

await client.calls.create({
  from: '+15125550100',
  to:   '+15558675309',
  url:  'https://example.com/twiml.xml',
})
voepy
after.ts
import { voepy } from '@voepy/sdk'

const client = new voepy({ apiKey: KEY })

await client.calls.dial({
  from: '+15125550100',
  to:   '+15558675309',
  record: 'on-demand',
})

Stuck on XML markup? An adapter shim lets you point your existing <Response> URL at us and migrate piece-by-piece. Otherwise, prefer call control: it's faster to debug, and the latency tail is half.

Pattern

Build a call center in 50 lines.

No SIP refer dance, no custom bridge orchestration. Conferences are the bridge. Recording starts on the conference, not the leg.

    await client.calls.answer(payload.call_control_id)

    const conf = await client.conferences.create({
      call_control_id: payload.call_control_id,
      name:            `call-${payload.call_session_id}`,
    })

    // dial leg B → connect an agent
    await client.conferences.dialIn(conf.id, {
      to:   pickAgent(payload.from),
      from: payload.to,
    })

    await client.conferences.recordStart(conf.id, { format: 'mp3' })
    await client.conferences.transcriptionStart(conf.id)
  }

  res.sendStatus(200)
})

Either party hangs up → conference ends, recording saved, transcription processed, webhook delivered. Carrier-side SIP retry dedup is built in — your handler stays idempotent.

Frequently asked

Questions worth answering plainly. If yours isn't here, the engineer who'd fix it is one email away.

Do I have to rip out Twilio in one weekend?
No. Most teams move one route at a time — outbound first, then inbound, then conferences. The verb surface matches 1:1, so you can A/B traffic between providers in your own router for as long as you want. We've had teams run dual-write for a quarter before fully cutting over.
What's actually in the sandbox?
$5 of test balance, a real US number, and the full production surface — every verb, every webhook, every response shape. The only difference is traffic terminates on a synthetic carrier so you don't pay per-minute while you're wiring things up. No card, expires in 14 days, renewable.
Is the pricing genuinely 30–60% lower?
Yes, and it's line-itemed. US-domestic outbound is $0.0085/min vs Twilio's $0.0140. Conferences, recording, transcription, and AMD are all priced separately at carrier-pass-through plus a flat 40% markup we publish in the rate card. No premium routes, no MIN_USD, no per-region surprises.
How do you handle SIP REFER and inbound retry dedup?
SIP REFER is exposed as calls.refer with the full RFC 3515 envelope. Inbound retry dedup is built into the edge — duplicate INVITEs within a 30-second window collapse to a single webhook delivery, keyed on Call-ID + CSeq. You don't write that code. We did.
Where can I terminate calls?
US, Canada, EU-27, UK, Australia, Singapore, Japan, Brazil, and Mexico in MVP. Pakistan and India dial-in are on a waitlist — message us if that's a blocker for you. Outbound termination covers the same regions plus another 60 ITU country codes via two upstream carriers with automatic failover.
How do you reconcile carrier CDRs against your invoice?
Nightly. Every call your account billed against gets matched to its carrier CDR by call-ID, duration, and source IP. Drift over 1% pages on-call automatically. The reconciliation log is queryable by your finance team — not buried behind a support ticket.
Is there a self-hosted option?
Not in MVP. The economics of running carrier interconnects on someone else's hardware don't pencil out for the team sizes we currently serve. If you're a regulated workload that genuinely needs an air-gap, talk to us directly — we've done one private deployment, and the rules for the second one are still being drawn.
