Twilio

Twilio is the most-used channel in Insighto for both voice and SMS. You connect it once at the workspace level; from then on, any phone or SMS widget you create can use it. Picking Twilio gets you the best US coverage, the smoothest A2P 10DLC path for compliant text messaging, and reliable voice quality across most regions.

When to pick Twilio​

  • US-heavy traffic — best deliverability, easiest 10DLC compliance, broadest carrier reach.
  • Voice + SMS in one place — you only manage one carrier instead of stitching two.
  • You want the fastest path to "going live" — Twilio's onboarding and number provisioning is the most mature of the three.

If you're price-sensitive on international voice, look at Plivo. If you need carrier-grade quality at high call volume, look at Telnyx.

How it works​

Add your credentials​

  1. In Twilio Console, copy the Account SID and Auth Token from the dashboard home.
  2. In Insighto, open Settings → Channels → Twilio.
  3. Paste both and click Save.

A green check means Twilio accepted the credentials and the numbers on your account are now visible to Insighto.

What Insighto wires up​

When you attach a Twilio number to a phone widget, Insighto sets the number's Voice → A call comes in webhook to:

https://api.insighto.ai/api/v1/call/initiate_call/{widget_id}

You don't paste this URL anywhere — Insighto sets it on the Twilio number for you. You can verify by looking at the number's configuration page in Twilio Console.

For SMS widgets, Insighto sets the Messaging → A message comes in webhook the same way.

A2P 10DLC​

If you're sending SMS to US numbers, you must register your brand and at least one campaign with US carriers (10-digit long codes — "10DLC"). This is done in Twilio's console, not Insighto:

  • Brand registration — your business identity. One-time per Twilio account.
  • Campaign registration — what you're going to text people about. One per use case (support, marketing, 2FA, etc.).

Allow 1–2 weeks for full approval. Unregistered traffic is heavily throttled or blocked by US carriers.
