A call comes in on a business phone number
Before a manager takes the call from a separate phone app, with nothing recorded on the client's card.
After the number is tied straight into the CRM, so the call lands on the right record by itself.

Calls, texts and messages built into your own systems — instead of a separate phone app nobody checks
Twilio is a US communications platform where every channel — calls, texts, messaging apps — has its own connection module. We build exactly the piece your business needs: a call that lands on a client's card, a text that goes out on its own, or a phone number tied straight into your website — instead of your team learning and paying for a separate calling app.
What we connect
- Each communication channel — calls, texts, messaging apps — connects through its own separate module, so we build only the piece your business actually uses.
- A phone number can be tied straight to your site or CRM, so an incoming call or text lands where your team already works.
- Access to your account is controlled through separate access keys with different levels — full, standard or narrowly limited to one task — and any of them can be switched off in a moment.
- If your team uses an app built on Twilio — a calling widget, a chat button — a separate short-lived access code lets that app work safely without exposing your main account keys.
- The moment a call or message happens, Twilio can notify your other systems right away, instead of them checking back in on their own.
- For anything a ready-made piece doesn't cover — a custom call flow, a specific messaging scenario — we build it ourselves on Twilio's open interface.
Automation scenarios
A client needs a text reminder
Before someone writes and sends the reminder by hand, if they remember.
After the text goes out on its own the moment an order status changes, without anyone typing it.
The team builds its own calling widget
Before giving the widget the same keys as the main account looks risky if the widget itself ever gets compromised.
After a separate short-lived access code lets the widget work safely without ever exposing the main account keys.
A call ends and needs to reach other systems
Before other systems have no idea anything happened until someone checks manually.
After Twilio notifies them the moment the call ends, so records update on their own.
How it works technically

Behind Twilio's REST-style interfaces sits a software layer that connects and optimizes communications networks around the world.

Limits
There's no single overall number for how many requests a connection can send — Twilio sets that ceiling separately for each product and channel in its own part of the documentation, not as one general rule for the whole account.

Questions
Does Twilio replace our CRM?
No — Twilio is the communications layer. We connect it to whichever CRM or system you already use, so calls and messages land there automatically.
Is it safe to give an app access to our account?
Access is controlled through separate keys with different levels, from full to narrowly limited to one task, and each of them can be switched off in a moment.
How does Twilio tell our other systems that a call happened?
The moment a call or text happens, Twilio notifies other systems right away, instead of them constantly checking whether anything is new.
Can you build something very specific for us, beyond the ready-made pieces?
Yes — for anything a ready module doesn't cover, we build it ourselves on Twilio's open interface for the exact task.
Tell us what needs to be connected
Describe the task in text or a voice message. We look at your setup and reply with a plan.
