Elevate Your WordPress Site with AI-Powered Inbound Calls: Connecting DialBunny to Vapi

In the evolving landscape of customer engagement, blending human oversight with AI efficiency is key to scaling operations without sacrificing personalization. For WordPress users relying on the DialBunny plugin to manage calls and texts via Twilio, integrating Vapi which is an advanced voice AI platform that unlocks a new level of automation. This setup routes inbound calls from your Twilio number directly to a Vapi-built AI voice assistant, which can handle greetings, FAQs, lead qualification, and even call transfers, all while keeping your DialBunny dashboard as the central hub for monitoring and fallback. As of September 2025, this integration leverages Twilio’s robust telephony with Vapi’s configurable AI agents, empowering solopreneurs and teams to provide 24/7 responsive service without constant manual intervention.

Vapi excels at creating conversational voice agents that feel natural, supporting over 100 languages and integrating seamlessly with Twilio for inbound routing. By configuring your Twilio phone number to forward calls to Vapi’s endpoints, the AI takes over initial interactions and transcribing speech in real-time, responding via text-to-speech.

Prerequisites: Setting the Foundation

Before diving in, ensure you have the essentials in place:

• Active Twilio Account: With a purchased phone number capable of voice calls (local or toll-free). Note your Account SID, Auth Token, and the phone number’s SID—these are your bridge to both DialBunny and Vapi.
• DialBunny Installed: As a WordPress plugin, it’s already connected to Twilio for dashboard-based call management. If not, install it from the WordPress repository and input your Twilio credentials in DialBunny > Setup.
• Vapi Account: Sign up at vapi.ai (free tier available for testing). Vapi’s dashboard is developer-friendly, offering templates for assistants like customer support or appointment booking.
• WordPress Site: Running on HTTPS for secure WebRTC audio in DialBunny, with admin access.

With these, you’re ready to wire up the AI magic. The process typically takes a quick 2 minutes!

Step 1: Configure Your Vapi Assistant

Start in the Vapi dashboard by creating a new assistant tailored to your needs—say, a support bot that fields inquiries about your products.

1. Log into dashboard.vapi.ai and click Assistants > Create Assistant.
2. Choose a template (e.g., “Customer Support Specialist”) or build from scratch. Customize:
   • Voice: Select from 100+ options, like ElevenLabs for natural tones.
   • Model: Use OpenAI’s GPT-4o for intelligent responses or integrate custom LLMs.
   • Prompts: Define behaviors, e.g., “Greet callers warmly, qualify leads by asking for email, and transfer to human if unresolved.”
   • Tools/Functions: Add capabilities like database lookups (via API calls to your WordPress site) or calendar integrations for bookings.
3. Enable Transcriber (e.g., Deepgram) and Synthesizer for real-time voice processing.
4. Test in Vapi’s simulator—speak queries and refine until it handles edge cases smoothly.
5. Publish and note the Assistant ID (a unique string like asst_123abc).

Pro tip: Incorporate guardrails to prevent hallucinations, such as knowledge cutoffs or fact-checking functions.

Step 2: Import and Route Your Twilio Number to Vapi

After you create a Vapi Assistant all you need to do is connect it to the DialBunny plugin which shouldn’t take anytime at all.

1. Create Vapi SIP URL
2. Copy and paste the SIP URL into the DialBunny plugin

Real-World Applications and Benefits

This DialBunny-Vapi combo is a powerhouse for WordPress-driven businesses. E-commerce sites can automate order status checks, reducing support tickets by 40-60% based on Vapi user benchmarks. Agencies use it for lead qualification while AI gathers details, then transfers hot prospects to a live agent in DialBunny.

Benefits include:

• Cost Savings: Twilio’s $0.0085/minute + Vapi’s usage-based pricing (starts free) beats hiring night-shift staff.
• Scalability: Handle spikes in calls without added headcount; Vapi scales to millions of minutes.
• Insights: AI-generated summaries boost follow-up rates—e.g., tag contacts as “high-intent” in DialBunny.
• Compliance: Built-in recording consents and GDPR tools ensure secure, auditable interactions.
• Easily call a client manually from DialBunny if you need to speak to them yourself.

Potential challenges? Initial prompt tuning takes iteration, and accents may need transcriber tweaks but Vapi’s analytics help optimize.
