Why Choose Us

Why Choose an Official Retell AI Solution Partner

Retell gives you a powerful voice platform. As an official Retell AI partner, EnactOn adds the integrations, testing, and tuning that turn it into measurable savings for your business. We have run Retell at scale for CrossEven, across 10+ brands.

Approved by Retell

Retell has approved EnactOn into its Solution Partner program, giving our team partner resources and support, so complex builds move faster and stall less.

Outcomes You Can Measure

Progress is tracked in calls resolved, bookings made, and hours saved, so every phase earns its budget before the next one starts.

Usage Costs Forecast Early

Each quote projects Retell usage and telephony costs at your call volume, so the payback is clear before you commit.

One Team, Full Ownership

Agent design, integrations, testing, and support all sit with EnactOn's 80+ in-house engineers and a single accountable lead.

Intent-Driven Engineering

How We Deploy Retell With Intent-Driven Engineering

EnactOn’s Retell AI integration combines Intent-Driven Engineering, AI-assisted speed, and strict human oversight. Senior architects define the specification first, engineers govern every implementation decision, and each release passes four quality gates before reaching production.

Define the Intent First

Before configuration, we agree on the calls each agent covers, the actions it can take, the topics it avoids, and the moments it escalates to staff.

Accelerate Development with AI

AI drafts prompts, test calls, and function code quickly, so engineers focus on integrations, latency, and edge cases that shape caller experience.

Keep AI-Generated Code Governed

Raw AI-generated code never enters production. Every output is reviewed, refined, and validated by EnactOn's engineering team.

Pass Four Quality Gates

Releases are checked for function, security, performance, and safe deployment, and scripted test calls score accuracy and task completion.

Apply 13 Years of Experience

Experience connecting CRMs, booking tools, and healthcare systems since 2013 keeps integrations reliable from the first live call onward.

Compliance on Every Call

Consent, recording rules, and PHI handling follow our [HIPAA compliant software development](/solutions/hipaa-compliant-software-development/) standard, with Retell's BAA signed before PHI flows.

By The Numbers

Secure, high-speed products built for business growth

Our software is engineered for speed, security and scalability — delivering dependable performance for businesses of every size.

Development Process
01
STEP 1

Map Calls and Goals

We review call volumes, recordings, and outcomes to choose the call types that save the most time and money once a Retell agent handles them.

02
STEP 2

Design Flows and Integrations

We script conversations, define handoff rules and guardrails, and confirm connections to your telephony, CRM, calendar, or EHR before building.

03
STEP 3

Build and Test on Real Calls

Agents are built on Retell and run through hundreds of test calls covering accents, noise, and interruptions, with results shared every week.

04
STEP 4

Launch and Improve Weekly

The agent starts on a portion of live traffic, coverage widens as results hold, and outcomes flow into your wider AI integration stack.
