Twilio SMS & Voice Infrastructure

Twilio is the programmable telephony layer behind modern business communication — the phone numbers, SMS pipes and voice infrastructure that AI receptionists, missed-call text-back, and appointment reminders run on. We handle the setup, compliance registration, and integration so it just works.

What Is Twilio?

Twilio provides programmable phone numbers, SMS/MMS messaging, voice calling and verification APIs. It's rarely the product you see — it's the infrastructure underneath: when your AI agent answers a call, when a missed caller gets an instant text, when a customer receives an appointment reminder, Twilio is usually carrying it.

How We Use Twilio

01

Phone number provisioning and porting for AI voice agents (Vapi, Retell) without losing your existing business number

02

A2P 10DLC brand and campaign registration

the compliance step that keeps US business SMS from being carrier-filtered

03

Missed-call text-back systems that recover callers who would otherwise dial a competitor

04

Automated appointment reminders and confirmations that cut no-shows 40–60%

05

SMS follow-up sequences wired through n8n and your CRM

06

Call tracking, recording, and routing for multi-location businesses

Why Hire Us Instead of DIY?

Twilio is developer infrastructure — raw APIs, not an app. The expensive mistakes are compliance ones: unregistered A2P traffic gets silently filtered by carriers (your texts simply don't arrive), and misconfigured webhooks drop calls. We've registered dozens of brands, know what the carriers reject, and wire Twilio into your CRM and AI stack correctly the first time.

Investment

Twilio setup + A2P 10DLC registration from $750. Full missed-call text-back system from $1,500. Bundled free inside our AI voice agent implementations ($2,500 setup + $297/mo).

Häufig gestellte Fragen

What does Twilio itself cost?
Usage-based and cheap at SMB volume: ~$1.15/month per phone number, ~$0.008 per SMS, ~$0.014/minute for calls. A typical service business spends $20–$80/month on Twilio usage — the value is in what's built on top.
What is A2P 10DLC and do I really need it?
US carriers require businesses sending application-to-person SMS to register their brand and campaigns. Unregistered traffic is increasingly filtered — messages silently fail. Registration takes 1–2 weeks and is included in every SMS system we build.
Can I keep my existing business number?
Yes — we port numbers into Twilio (or host SMS on your existing number while calls stay put, via hosted SMS). Porting takes 1–3 weeks; we manage the whole process with zero downtime windows planned around your hours.
Twilio vs. the phone system in GoHighLevel?
GHL's phone system runs on Twilio under the hood (LC Phone). For GHL-centric businesses we configure it natively there; for custom AI stacks we use Twilio directly for full control. Same infrastructure either way — we pick the right wrapper.
Is this HIPAA-compliant for medical practices?
Twilio offers HIPAA-eligible services under a BAA. For healthcare clients we architect within Twilio's eligible products and pair them with compliant AI platforms — discussed case-by-case in your build.
