Connect Twilio with Topcalls AI voice agents

The short answer

Twilio is a cloud communications platform for SMS, voice, and messaging. Connected to Topcalls, an AI voice agent can send an SMS follow-up the moment a call wraps, look up a phone number to verify it before dialing, and start a fresh outbound campaign when a new Twilio recording finishes on the account.

What you can automate with Twilio

SMS the meeting link after the call

The moment a Topcalls voice agent books a meeting on the phone, Send SMS fires a text with the calendar link, meeting time, and location. The buyer sees the confirmation on their lock screen before they even open their laptop, cutting no-shows on scheduled calls significantly.

Verify the number with a Phone Number Lookup

Before dialing a fresh lead list, Topcalls runs Phone Number Lookup on every entry. The result marks bad numbers, wrong carriers, and mobile versus landline. Topcalls then skips invalid rows, saving budget at $0.35 per minute against numbers that would never have connected in the first place.

Trigger a call when a Twilio recording finishes

The New Recording trigger fires when a Twilio call recording becomes available. Topcalls consumes the recording, transcribes it in 36+ supported languages, and can launch a fresh outbound call to the same number for a targeted follow-up conversation with the right AI voice agent script.

React to inbound SMS with a voice call

The New Incoming SMS trigger fires when a customer texts a Twilio number with something like `call me now`. Topcalls parses the message, dials the same phone number under sub-500ms response latency once picked up, and opens with a script tuned to the SMS content.

Pull the transcription of a completed call

When Twilio finishes transcribing an inbound call, the New Transcription trigger sends the text to Topcalls. The AI voice agent uses the transcript to prepare a personalized outbound call the next day, referencing what the caller said in the original recording without asking them to repeat.

Frequently asked questions

Can Topcalls send an SMS after a call ends?

Yes. Topcalls uses Twilio's Send SMS action to fire a text the moment a voice call closes. The AI voice agent picks the template that matches the call outcome and personalizes the message with the meeting time, calendar link, or a promised document.

Does Topcalls verify phone numbers before dialing?

Yes. Topcalls calls Twilio's Phone Number Lookup on every fresh number to check carrier, line type, and validity. Invalid rows get skipped before dialing, so budget stays on numbers that can actually connect at $0.35 per minute, and the voice agent does not waste time on dead lines.

Can inbound SMS start a Topcalls outbound call?

Yes. The New Incoming SMS trigger fires when a customer texts a Twilio number. Topcalls parses the message body, checks intent, and places an outbound call to the same phone number within a few seconds using the voice profile you configured for that campaign.

Does Topcalls integrate with Twilio call recordings?

Yes. New Recording and New Transcription triggers surface Twilio audio and text to Topcalls the moment they are ready. Topcalls can reprocess the recording, feed the transcript into an AI voice agent briefing, or launch a follow-up outbound call using the same phone number.
