Overview
What you get with this package.
Every missed call is a missed customer. Every queue minute is a frustrated one. Every after-hours call goes to voicemail and most callers never call back. Codefree builds AI voice agents that handle the volume — answering customer questions, booking appointments, qualifying leads, running outbound campaigns — at any hour, in any language, without dropping quality call to call. Built on Twilio for telephony, ElevenLabs for natural voice synthesis, OpenAI Whisper for transcription, and OpenAI GPT-4 or Anthropic Claude for reasoning, with LangChain tool integration into your CRM (Salesforce, HubSpot, Zoho, Pipedrive). When something needs a human, the agent escalates cleanly with full conversation-context handoff. AI-native delivery on Claude Code and Cursor compresses the traditional 3 to 4 month voice AI timeline to 4 to 8 weeks. Three paths depending on your problem: Inbound Voice Agent for support triage and appointment booking, Outbound Campaigns for lead qualification and surveys with TCPA and DNC compliance built in, Voice in Your App for hands-free SDK integration into your mobile or web product. Pick the path that fits — Codefree will tell you straight on the kickoff call if the wrong one is selected.

Who This Is For
Is this the right fit for you?
This package is designed for specific types of people facing specific challenges. See if your situation matches.
Contact Center Director
Call volume is crushing your team and hold times are destroying customer satisfaction.
Your Challenges
•Long hold times driving customers to competitors and dragging down CSAT scores
•Hiring and training agents cannot keep pace with month-over-month call volume growth
•After-hours calls go unanswered or cost premium overtime rates that eat margin
•Same 20 questions account for 60 percent or more of tier-1 volume every week
What You Want
•Handle unlimited simultaneous calls without hold times, queues, or degraded quality
•Provide 24/7 coverage without staffing complexity, night shifts, or overtime costs
•Maintain consistent quality across all interactions regardless of caller volume or time of day
Your Outcome
Deploy voice AI that handles thousands of calls simultaneously — no hold times, 24/7 coverage, consistent quality on every call, and clean human escalation only when the AI genuinely cannot help.
Need Something Different?
Complex consultative sales calls where the relationship matters more than the volume. Industries where customers expect human-only interaction such as private banking, luxury concierge, or crisis counselling. Small-volume operations (under 100 calls per month) where the build cost will not recoup within 18 months.
1.Defined call flows or scripts for the scenarios to be automated (or a willingness to co-map them during the Discovery workshop)
2.CRM access with API scope for integration (Salesforce, HubSpot, Zoho, Pipedrive, Freshworks, or documented custom CRM)
3.List of common customer questions, answers, and edge cases the AI should handle
4.Telephony provider account (Codefree helps set up Twilio if you do not have one)
Process
How we work together.
Week 1
Discovery, call flow mapping, and persona design
Codefree runs 2 discovery workshops with your team to map call scenarios, define caller personas, gather training content (FAQ, product docs, policy pages), and produce a written architecture plan you sign off on before build starts.
Week 2-3
AI-native voice agent build and telephony integration
Codefree builds the voice agent on Twilio with ElevenLabs voice synthesis and OpenAI Whisper transcription. Call flows programmed, GPT-4 or Anthropic Claude reasoning wired via LangChain, telephony provider account configured. Daily Loom demos show progress.
Week 4-5
CRM integration, analytics, and escalation configuration
Connect the agent to your CRM (Salesforce, HubSpot, Zoho, Pipedrive, or Freshworks) for automatic call logging and contact attribution. Set up analytics dashboards, configure human escalation rules with full-context handoff, and wire compliance controls (consent, DNC, recording retention).
Week 6-8
Testing, 2-week soft launch, and production rollout
Extensive call testing across scenarios, accents, and edge cases. 2-week soft launch with calls split between human and AI while Codefree monitors CSAT and tunes. Once CSAT holds, full rollout. Hand over GitHub repository and 45-day post-launch bug-fix support kicks in from go-live.

FAQ
Common questions.
How natural does the AI voice actually sound?+
Codefree uses ElevenLabs voice synthesis, which is state-of-the-art in 2026 and sounds remarkably human. Most callers cannot tell it is AI — the voice handles natural pauses, intonation, and emotion. Per-language voice tuning is done during the build so English calls sound English-native and Hindi calls sound Hindi-native.
What happens when the AI cannot handle a call?+
The AI detects confusion, out-of-scope requests, or explicit human-agent asks and seamlessly transfers to your team with full context of the conversation. Your human agent sees the transcript so far, the caller's contact record from your CRM, and the reason for escalation — no repeat questions, no lost context.
Can the AI handle angry or frustrated customers?+
Yes — Codefree trains for sentiment detection and de-escalation. The AI stays calm, empathetic, and knows when to escalate to humans if sentiment drops below configured thresholds. Anger detection is one of the strongest signals for automatic human handoff in the default configuration.
How do you handle compliance for TCPA, GDPR, and call recording?

24/7 availability with no degradation in quality at 3am versus 3pm — the AI does not get tired
AI-native delivery on Claude Code and Cursor — production voice pipelines shipped in half the traditional timeline
+
Codefree implements the technical controls — consent capture at call start, do-not-call list compliance, region-aware recording, retention policies, and PII redaction. You are still responsible for the policy decisions (what to record, how long to keep it, which jurisdictions to include). Legal sign-off on your specific use case is yours to obtain.
What is the real per-call cost once the system is running in production?+
Voice infrastructure costs approximately 0.05 to 0.30 USD per minute depending on language, voice quality tier, and provider (Twilio for telephony, ElevenLabs for voice synthesis, OpenAI Whisper for transcription). You are billed by each provider directly, not through Codefree. A 1,000-call month at 2 minutes average runs approximately 200 to 600 USD in total infrastructure costs. Codefree gives you exact per-call projections during scoping.
What happens if customers hate the AI voice during launch?+
Codefree runs a 2-week soft launch where calls split between human and AI, monitor CSAT, and tune. If satisfaction drops more than 10 percent versus baseline, Codefree re-scopes the deployment (smaller use case, more aggressive human escalation, or a different voice). We do not ship something that hurts your CSAT.
Who is responsible if the AI says something wrong on a call?+
Output is constrained by guardrails Codefree installs — the agent can only say what is in its scoped knowledge base and cannot go off-script into hallucinated advice. Codefree tests extensively for edge cases. Ultimately, the AI operates under your business, so the liability model is the same as a human agent. Every call includes recording and full transcript so any incident is auditable.
What is the uptime guarantee for the voice AI system?+
Codefree deploys with redundancy across regions and providers — typical uptime is 99.9 percent or higher. There is no penalty SLA included by default (that is enterprise contract territory), but Codefree monitors and responds to production incidents within 1 hour during business hours.
What is included in the 1,000 call minutes, and what happens after I use them?+
Every package includes 1,000 call minutes to get you started — enough to test, tune, and validate the system under real load during the 2-week soft launch. After that, you pay only for what you use through your telephony provider (typically 0.01 to 0.05 USD per minute on Twilio depending on volume and region). Codefree helps you set up the provider account during the build and forecasts costs based on your expected call volume.
How long does it take from kickoff to launch, and what is the process?+
Timeline is 4 to 8 weeks depending on complexity and how quickly you provide call flows and CRM access. Codefree starts with discovery to map your call scenarios, then builds and trains the voice agent, integrates with your CRM and telephony stack, and finishes with extensive testing before the 2-week soft launch. You have weekly video calls and Slack access throughout the build.
Can I switch between Inbound, Outbound, and Voice-in-App paths after starting?+
Each path is scoped and priced separately because the call flows, integrations, and compliance requirements differ significantly. If you want to add a second path mid-project or after launch, Codefree treats it as a new engagement with its own timeline and pricing. Most clients start with one path, validate it, then expand once they see results.
Which CRM systems do you integrate with, and what if we built our own?+
Codefree integrates with standard CRMs like Salesforce, HubSpot, Zoho, Pipedrive, and Freshworks out of the box. If you have a custom-built CRM, Codefree can integrate via REST or GraphQL API as long as you provide documentation and access — but custom CRM development itself is not included and may extend the timeline by 1 to 2 weeks.
Do I need a telephony provider account before we start, or can Codefree set that up?+
You do not need one before kickoff — Codefree helps you set up a Twilio account (or another provider if you have a preference) during the project. You own the account and pay telephony costs directly to the provider, which keeps your per-minute rates low and gives you full control and visibility.
How many revisions do I get, and what counts as a revision?+
You get 3 rounds of revisions during the build phase — changes to call flows, voice tone, escalation logic, or CRM mapping based on testing feedback. Revisions refine what Codefree scoped, not entirely new call scenarios or integrations. If you need more than 3 rounds, we quote additional revision cycles separately.
What if our call volume is unpredictable or seasonal — can the system scale?+
Yes — that is the core advantage of AI voice agents. They handle 10 calls or 10,000 simultaneously without degradation, so you never pay for idle capacity during slow periods. The system auto-scales based on real-time demand, and you only pay for actual call minutes used, making it ideal for seasonal spikes or unpredictable volume.
What does the 45-day post-launch support cover, and what happens after that?+
For 45 days after delivery, Codefree handles bug fixes, call flow tweaks, and minor adjustments via Slack or email at no extra cost. After that window, you can purchase ongoing support separately via the Extended Support Retainer add-on, or handle minor changes yourself if your team has technical capacity. Major feature additions or new call flows are quoted as new work.
