6 steps to build an AI phone call assistant without code

Want to build an AI phone call assistant but don't know how to code? No problem! Here's a step-by-step guide to building your very own AI phone call assistant without writing a single line of code:

Step 1: Choose a no-code AI phone assistant platform

First things first, you need to choose a platform that lets you build your AI phone call assistant without coding. Some options include Lindy, Goodcall, and IsOn24. When choosing a platform, consider features like call answering, CRM integration, and analytics. 

For example, Lindy offers a user-friendly visual interface and a wide range of features, including the ability to handle inbound and outbound calls, integrate with popular business tools like Salesforce to take key data from said calls to update your knowledge base and much more. 

Step 2: Define your AI call assistant's purpose

Before you start building your AI call assistant, ask yourself these big questions. What do you want it to do? Do you need it to handle customer support, qualify leads, or schedule appointments? 

Once you know its purpose, you can start identifying common call scenarios and questions the AI should handle. 

For example, if you're building an AI call assistant for customer support, you'll need to determine the most common customer questions and issues. You can then add this info to a knowledge base that the AI model of your choice will query to answer questions accurately.

If you're building an AI call assistant for lead qualification, you'll need to pinpoint the criteria that qualify a lead as a good fit for your business. You can then use this information to instruct the AI to ask the right questions and spot qualified leads.  

Step 3: Customize your AI phone assistant's responses

Many no-code platforms offer pre-built response templates. For example, Lindy offers a Phone Call Assistant template that you can customize in Lindy’s drag-and-drop interface. 

You simply add actions, triggers, and conditions, so your assistant will behave the way you want to and fetch data from relevant files or platforms. The best part? In some modules, you can use natural language to instruct the AI model you choose on how to act. 

You can also set up rules to make sure a human agent steps in when needed. For example, if a caller asks a question the AI can’t answer or if the caller sounds frustrated, the assistant can transfer the call to a live representative. This way difficult issues are handled by a person instead of the AI.

Step 4: Integrate with business tools

Connect your AI call assistant to your calendar, CRM, or helpdesk software. No-code AI automation platforms like Lindy offer integrations with Gmail, Salesforce, Zoom, and all modern business apps and tools. 

For example, you can link your AI call helper with your CRM to automatically log call data and update customer records. With Lindy, this is all done with individual modules you can string together.

Step 5: Test your AI call assistant

Run test calls to check for accuracy and natural-sounding responses. For example, you can ask a colleague to call your AI assistant and ask it a few questions. 

This will help you to identify areas where the AI needs improvement. You can use Lindy’s Make Phone Call action to transcribe the call, then automatically send the notes to an AI agent like ChatGPT to give feedback about how the call went. 

Step 6: Deploy and monitor performance

Activate your AI phone assistant on your business phone line or VoIP system. Monitor call analytics and refine responses based on customer interactions. 

For instance, you can track how often the AI successfully resolves issues, identify recurring customer concerns, and analyze sentiment to fine-tune responses. These insights help you train the AI to handle more difficult interactions and keep customer satisfaction high.
