Calls inside your app
Outbound and inbound calls, click-to-call from a customer record, call status and recordings, built on the Twilio Voice API.
Call tracking
Every call attached to a lead, customer or deal with its outcome, and a dedicated number per campaign when you need to know which source rang.
Call queues for teams
Each lead reserved to one agent, released when an agent goes idle, and live updates on every screen, so two people never dial the same prospect.
SMS and WhatsApp
Confirmations, reminders and two-way messages through the same webhook pipeline, with inbound replies forwarded to your team.
Phone verification
One-time codes for signup and login, tested end to end in development without sending a real SMS.
Cost and compliance
Spend alerts, retry caps, recording consent and retention rules set in code, with EU data handling under GDPR.
Common questions
How much does it cost to run a call tracking system with the Twilio Voice API?
There are two separate costs. Twilio bills you directly for usage: phone numbers per month, calls per minute and messages per message, with rates that vary by country, number type and volume, so check Twilio's pricing page for the countries you call. Building the system is a one-time cost: we quote it as one fixed price after a scoping call, and a first version of calling with call tracking in an existing product is typically two to three weeks of work. We add spend alerts and retry caps so the usage bill stays predictable.
How much does a Twilio integration cost to build?
One fixed price, quoted after a free scoping call, never by the hour. A solid first version of calling in a SaaS product (outbound and inbound calls, status tracking, call history on the customer record and a mock for testing) is typically two to three weeks on top of an existing backend. A full agent queue with reservations and live screens adds a few more weeks. Book a free 30-minute call and you get the price and date in writing within 48 hours.
Have you built Twilio integrations before?
Yes. For Circle Hospitality, a hospitality staffing agency, we built the Twilio layer their team uses to call and message staff about shifts: one webhook endpoint for voice calls, call status, inbound SMS and WhatsApp, phone verification, and follow-up by email, push and WhatsApp when a call goes unanswered. The details are in our Twilio Voice API write-up.
Can you add phone calls to our existing SaaS?
Yes, that is the usual job. We work inside your codebase and connect calls and messages to the records you already have, so nothing lives in a separate tool your team has to check. We build on Laravel most of the time, as in the Laravel development work we do, and the code is yours on handoff.
Can you build a call center or sales dialer on Twilio?
Yes. For most SaaS products we build a focused call queue inside your own app: each lead reserved to one agent, reservations released when an agent goes idle, outcomes that schedule the next call, and live updates on every agent's screen. Twilio also offers TaskRouter and Flex for full contact centers. We tell you on the scoping call whether you need them; for most products a queue in your own app is simpler and cheaper.
Can an AI agent answer the calls instead of a person?
Yes. That is our voice AI agents service: an agent that answers the line, books appointments, qualifies leads or answers support questions, and hands the call to a person when it needs one, with everything logged to your CRM.
Is Twilio call recording GDPR compliant?
It can be, if it is designed that way. Consent rules for recording differ by country, and in the EU a recording is personal data. We decide with you who can hear recordings, how long they are kept and where they are stored, then enforce the retention in code rather than in a policy document. We are an EU company in Estonia and work under EU contracts.
