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.
To get started, you’ll need an active Twilio account with a purchased phone number that supports voice calls, whether local or toll-free. Make sure you have your Account SID, Auth Token, and the phone number’s SID handy, as these credentials act as the connection point between DialBunny and Vapi. DialBunny should be installed as a WordPress plugin and connected to Twilio for managing calls directly from your dashboard and if it isn’t already, you can install it from the WordPress repository and enter your Twilio credentials under the DialBunny settings page. You’ll also need a Vapi account, which you can create at vapi.ai using their free tier for testing. Vapi’s developer-friendly dashboard includes ready-made templates for common assistants like customer support or appointment booking. Finally, ensure you have a WordPress site running on HTTPS as secure HTTPS is required for WebRTC audio to function properly within DialBunny.
With these, you’re ready to wire up the AI magic. The process typically takes just a quick 2 minutes!
Start in the Vapi dashboard by creating a new assistant tailored to your needs—say, a support bot that fields inquiries about your products.
Log into dashboard.vapi.ai and navigate to Assistants > Create Assistant, where you can either choose a prebuilt template, such as Customer Support Specialist, or build an assistant from scratch. From there, customize the assistant by selecting a voice from over 100 options, including natural-sounding providers like ElevenLabs, and choose a model such as OpenAI’s GPT-4o for intelligent, conversational responses or a custom LLM if preferred. You can then define prompts that shape behavior, for example instructing the assistant to greet callers warmly, qualify leads by asking for an email address, and transfer the call to a human if the issue isn’t resolved. Enhance functionality by adding tools or functions like database lookups through API calls to your WordPress site or calendar integrations for appointment bookings, and enable a transcriber (such as Deepgram) along with a synthesizer for real-time voice processing. Once configured, test the assistant using Vapi’s simulator by speaking sample queries and refining responses until edge cases are handled smoothly.
Pro tip: Incorporate guardrails to prevent hallucinations, such as knowledge cutoffs or fact checking functions.
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.
Simply go to the AI Assistant section in the DialBunny dashboard and enter in the SIP URL into the corresponding Vapi SIP URL input from within the plugin.

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.
Using DialBunny with Twilio and Vapi delivers meaningful cost savings by replacing expensive staffing with low, usage-based fees. Twilio’s calls average around $0.0085 per minute, while Vapi’s pricing starts with a free tier and scales only as usage increases. The setup is highly scalable, allowing you to handle sudden spikes in call volume without adding headcount, as Vapi can scale to millions of minutes seamlessly. You also gain valuable insights through AI-generated call summaries, which improve follow-up effectiveness by letting you tag and prioritize contacts in DialBunny, such as marking leads as “high-intent.” Then when when a conversation requires a personal touch, you can easily place a manual call to a client directly from the DialBunny dashboard.
Connecting DialBunny to Vapi isn’t just an integration; it’s a leap toward intelligent, always-on communication embedded in your WordPress ecosystem. With DialBunny as the glue, inbound calls become proactive conversations that nurture relationships and drive growth. Head to vapi.ai to spin up your first assistant, and watch your DialBunny dashboard light up with smarter interactions.
