AI Inbound Call Agent for Twilio
Defined call types handled end to end on your Twilio number, with each call's record and recording kept in Twilio.
Your Twilio number already carries order checks, dispatch requests and general questions, and your team cannot take them all. This agent answers that number and works each call type through to an outcome. Recordings stay in your Twilio account, follow-up texts go from the same number, and outcomes are written back on a mapping you approve. You keep the account, the number and the data.
- Handles up to five call types end to end on Twilio
- Keeps every recording and call record in your own Twilio account
- Sends follow-up texts from the same Twilio number

What it is
AI Inbound Call Agent for Twilio runs the inbound call types you define, such as order checks or dispatch requests, on a number in your Twilio account. It takes each call through to an outcome, reads and updates Twilio voice calls, numbers, recordings and SMS on an agreed mapping, and connects one more system.
Why businesses buy it
When a Twilio line is answered by busy staff, routine calls queue up and the ones that matter wait. Many voice bots also store recordings in their own system, so your call history ends up split. This edition answers on your Twilio number, finishes each defined call type and writes the result back where your developers and managers already look. The Scope Card names the Twilio objects, the five flows and the one extra system before you buy, so there is no open-ended developer project to manage.
Problems this solves
Order-status calls on your Twilio line keep staff from other work
The agent runs your defined call types, such as order checks, on a number in your Twilio account. It looks up answers in the one other system you connect and takes each call to an outcome.
Twilio recordings pile up with no note of what each call achieved
Each call is taken to a clear outcome and written back to Twilio on the agreed mapping. Recordings sit with their call, so you can see what happened without replaying everything.
Building call logic on Twilio yourself takes developer time you lack
Up to five call flows are configured for you on your existing Twilio account. The field mapping is documented, so your team can see exactly how the agent uses Twilio.
Sharing Twilio credentials with outside developers feels unsafe
Access is set up through keys you control, and no keys are sent by email. Testing runs on sandbox or test records, and the results are written up in a test report.
A good fit if
Your inbound line carries several kinds of call, for example order checks, dispatch requests and general questions, and the number already sits in Twilio.
You want every call's recording and record to stay in your own Twilio account rather than in a vendor's storage.
Some calls should finish with a short text to the caller, and that text should come from the same Twilio number.
Someone on your side holds Twilio admin rights and can give 30 minutes to a setup call.
Not the right fit if
Your calls are mostly front-desk work: opening hours, bookings and transfers. See AI Voice Receptionist for Twilio, which is shaped around a reception script.
Your phones run on another platform. See AI Inbound Call Agent for Vonage, or AI Inbound Call Agent for RingCentral.
You do not need anything written back into Twilio itself. The core AI Inbound Call Agent, connects to your telephony account without a Twilio field mapping.
You want ongoing two-way text conversations on the number, not one follow-up text. Add the SMS Channel Add-on, with this build.
How it works
- Setup starts with your Twilio admin. On a 30-minute call we confirm which Twilio number the agent answers and agree the field mapping, using the account SID and API key you supply.
- Each caller is matched to one of up to five flows. Someone asking about an order goes down a different path from someone booking a dispatch, and each path asks only what it needs.
- The flow runs to an outcome. The agent checks the one other system you connected, such as your CRM, answers from up to 50 documents or an FAQ set, and completes the step that flow allows.
- Anything outside those flows goes to a person. Live transfer sends the caller to the number set for that call type, and low confidence triggers the same handoff.
- Twilio keeps the record. The call, its recording and any text sent from your number are written back through the documented mapping, so your Twilio account holds the full history.
What you provide within 72 hours
Your portal lists these the moment you order. Delivery starts the working day after everything is in and your access is checked.
- Your Twilio account SID and an API key for the account that holds the number.
- Thirty minutes of your Twilio admin's time for the setup call.
- The number the agent should answer, or the one you will port or forward into Twilio.
- A short description of each call type, with the scripts, FAQs and business hours behind it.
- A transfer number for each call type.
- Calendar or CRM access for the one additional system.
- Your preferred voice, your call-recording disclosure wording, and the one person who approves decisions.
- An API key for your own AI model account (for example OpenAI or Google Gemini), created for this build with a spending limit.

Expected benefits and how to measure them
- Can handle defined inbound calls on Twilio without extra headcount.
- Helps every Twilio call end with a recorded outcome.
- Makes the Twilio setup easier to hand over to your own team.
- Calls taken to a recorded outcome
- Count calls with an outcome in Twilio each month. Compare call types to spot flows that need refining.
- Staff time on order-status calls
- Staff tally these calls for two weeks before launch. Compare with the agent's call log after.
- Calls transferred to staff
- Use Twilio call logs. Track the monthly trend after launch.
Before you start: Export four weeks of Twilio call logs and tag a sample by call reason. Note how long staff spend on order checks each week.
These are things to track, not promised results. Outcomes depend on your data, your team and your market.
Running costs
The build is paid once. Twilio bills you directly for minutes, texts and number rental. All in, the voice platform, AI model and telephony come to roughly $0.13 to $0.31 per call minute, plus that rental. A dispatch flow with several questions uses more minutes than a quick order check, so your mix of call types shapes the bill.
AI usage during the build and testing is billed to your own accounts as well. Twilio plan upgrades are not part of this build.
Ask about running costsCustom requirements
A sixth call flow, a second Twilio number, or custom Twilio objects outside the agreed mapping need a written Change Quote. Add a note at checkout and the quote arrives.
Request a custom versionKeep it running
After the 30 days of support, optional monthly maintenance keeps the line answering well: monitoring, fixes, model and Twilio updates and a monthly health report. Change hours handle small changes like new opening hours or a reworded call flow. Larger changes get a Change Quote. Cancel any month.
$320/mo (5% of the build price a month, includes 3 change hours)
Optional. Starts after the post-launch support period. Cancel any month.
How maintenance worksHow this compares
| Do it yourself with a SaaS tool | Hire a custom agency | Upmark Labs | |
|---|---|---|---|
| Price | A hosted voice bot on Twilio adds a platform fee on top of your minutes | A Twilio developer usually bills by the hour | Ours is one fixed price, shown on this page before you buy |
| Where records live | Often in the bot vendor's own dashboard | Depends on what was built | Ours writes calls, recordings and texts back to your Twilio account |
| Call types | Usually one script per number | Agreed as the project goes | Ours covers up to five flows with live transfer |
| Delivery | Sign-up is quick, building the flows is on you | Set per project | Ours has a fixed delivery time shown before you buy, with faster options |
Questions about this product
Which Twilio records does the inbound call agent read and write?
Voice calls, phone numbers, recordings and SMS. It picks up the call as it arrives on your Twilio number, and when the flow ends it writes back the outcome fields agreed in the mapping, keeps the recording in Twilio and logs any text it sent. Custom Twilio objects beyond the documented mapping are outside this build.
Can AI Inbound Call Agent for Twilio text the caller after the call?
Yes, where a flow calls for it. A single follow-up text, such as confirming what was agreed on the call, can go from the same Twilio number because SMS is part of the mapping. A back-and-forth text conversation is a separate channel, sold as the SMS Channel Add-on for $1,500 alongside this build.
How does the Twilio inbound edition differ from AI Voice Receptionist for Twilio?
The receptionist is shaped around front-desk work: routine questions, bookings and transfers. This edition is for call types you want handled end to end, such as order checks or dispatch requests, each with its own questions, lookups and recorded outcome.
What Twilio credentials does the inbound call agent need?
Your Twilio account SID and an API key, plus a Twilio admin for a 30-minute setup call. Nothing is requested by email. The connection is scoped to the number this agent answers, and testing runs on sandbox or test records before the agent takes a single live call.
How long does the Twilio inbound build take, and what does faster delivery cost?
Both are in the delivery panel on this page, with the standard timeline and each faster option priced up front. The clock starts the working day after your Twilio account SID, API key, call scripts and transfer numbers are confirmed, so a complete intake protects the date. Fifty test calls and two change rounds sit inside every speed option.
Are Twilio usage charges billed through Upmark?
No. Twilio bills you directly for minutes, texts and number rental in your own account. All in, including the voice platform and AI model, expect roughly $0.13 to $0.31 per call minute plus rental. We take no cut of call volume, and monthly maintenance is optional.
Can several Twilio numbers feed the same inbound agent?
The build answers one number. You can forward other numbers into that one with no change to the build, and the flows treat those calls the same way. If a second number needs its own greeting, flows or records kept apart, that is a Change Quote, priced before any work starts.
