Quickstart

This guide walks you through connecting a Twilio Elastic SIP trunk, creating your first AI voice agent, and making your first test call.

​

Prerequisites

Before you begin, ensure you have:

• A RevRing account with access to the dashboard
• A Twilio account with Elastic SIP Trunking enabled
• At least one phone number provisioned in Twilio

​

Step 1: Connect Your SIP Trunk

SIP trunks connect your AI agents to the phone network, enabling both inbound and outbound calling.

​

Configure Twilio

1. Log into your Twilio Console
2. Navigate to Elastic SIP Trunking → Credential Lists and create a new Credential List with a username and password
3. Go to Elastic SIP Trunking → Trunks and create or select an existing trunk
4. In Origination, add an Origination SIP URI: sip:sip.revring.ai
5. In Termination, note your Termination SIP URI (e.g., yourtrunk.pstn.twilio.com)
6. In Termination → Authentication → Credential Lists, select your Credential List
7. Assign your phone numbers to the trunk in the Numbers tab

​

Add the Trunk to RevRing

1. Navigate to SIP Trunks in your RevRing dashboard
2. Click Add SIP Trunk
3. Fill in the form:
   • Name: Twilio Elastic (or any descriptive name)
   • Proxy: Your Twilio Termination SIP URI from step 5 above (e.g., yourtrunk.pstn.twilio.com)
   • Username: Enter the username from your Twilio Credential List
   • Password: Enter the password from your Twilio Credential List
   • Phone Numbers: Enter your phone numbers in E.164 format, separated by commas (e.g., +12025551234, +14155552671)
4. Click Add Trunk

​

Step 2: Create Your First Agent

Agents are AI-powered voice assistants that handle phone conversations based on the instructions you provide.

​

Create the Agent

1. Navigate to Agents
2. Click New Agent
3. Enter a Name (e.g., Sales Assistant)
4. Click Create

​

Configure Agent Behavior

After creation, you’ll be taken to the agent detail page with several tabs. Configure the Overview tab:

1. SIP Trunk: Select the trunk you just created
2. Status: Set to Active to enable the agent
3. First Message: Enter an opening greeting (optional)
   Copy

   Hello! Thanks for calling. How can I help you today?
   
4. Prompt: Define how the agent should behave during calls
   Copy

   You are a helpful sales assistant for Acme Corp. Your role is to:
   - Greet callers warmly
   - Answer questions about our products and services
   - Collect contact information if they want a callback
   - Transfer to a human rep if needed
   
   Be professional, friendly, and concise. Keep responses under 30 seconds.
   
5. Click Save

​

Configure Voice Settings

Switch to the Voice tab to customize how your agent sounds:

1. Voice: Select a voice that matches your brand (click play to preview)
2. Click Save Voice

​

Step 3: Test Your Agent

The test panel on the right side of the agent page lets you call your agent directly from the browser — no phone required.

​

Make a Test Call

1. Open your agent and look at the test panel on the right
2. Click the call button (microphone icon) to start a WebRTC call
3. Speak into your computer’s microphone — you’re now talking to your agent
4. Click the button again (X icon) to end the call

The Transcript section updates in real time as the conversation progresses. After the call ends, review the full transcript to check for errors or unexpected behavior.

​

Send an Outbound Test Call

To test outbound calling over the phone network (real SIP calls):

1. Navigate to Send Call
2. Select your Agent, enter a From Number and To Number
3. Click Send Test Call

The call will initiate within seconds. Answer your phone to speak with your agent.

​

Iterate and Improve

Based on your test call:

1. Return to the Overview tab
2. Refine your Prompt to improve agent responses
3. Adjust First Message if needed
4. Make another test call to validate changes
