What is MCP and why does it matter?

MCP (Model Context Protocol) is the open standard developed by Anthropic that lets AI agents connect to any business tool. It means our agent can book in your calendar, look up your database, or update your CRM — in real time during the call.

Will callers know they're talking to an AI?

Our agents are transparent when required, but they sound and respond like humans. Most businesses choose to disclose — and customers don't mind when the experience is faster and more helpful.

How long does integration take?

A standard integration with 2-3 MCP servers takes 2-5 business days. We handle the setup.

What happens when the AI can't resolve an issue?

The agent seamlessly transfers the call to a human agent with a full context summary. No caller left behind.

Is my customer data secure?

All calls are encrypted in transit and at rest. We offer SOC2 compliance as standard and HIPAA compliance for healthcare customers.

Do you support languages other than English?

Yes. Our agents support 30+ languages. Spanish, French, Portuguese, German and more out of the box.

Build vs. Buy: AI Voice Infrastructure for Your Business

Large enterprises face a critical question: should they build their own AI voice infrastructure or buy a managed platform like CallToAgent?

The Building Blocks of AI Voice

Building an AI voice agent requires:

ASR (Speech-to-Text): Deepgram or similar.
LLM (Logic): GPT-4 or Anthropic Claude.
TTS (Text-to-Speech): ElevenLabs or similar.
Telephony: Twilio or SIP Trunks.
Integration Layer: The hardest part — connecting it all to your business tools.

The Cost of Building

Most companies underestimate the Development Time (weeks or months) and the Technical Debt of maintaining low-latency websockets and proprietary telephony integrations.

The CallToAgent Advantage

By choosing CallToAgent, you get:

Deployment in Days: Not months.
Pre-built MCP Connectors: No custom API coding.
Optimized Latency: We've already co-located our infrastructure for < 300ms roundtrip.
Predictable Pricing: Flat monthly fee instead of variable token/minute billing.

If your core business isn't telephony infrastructure, buying is the smarter move.
