This guide will help you understand and set up SIP integration. If you need clarification during setup, our support team is available to assist.

What is SIP Integration?

SIP (Session Initiation Protocol) integration allows you to connect your existing phone system to Autocalls.ai. Think of it as building a bridge between your current phone setup and our AI platform. This means you can:

  • Use your existing phone numbers with our AI assistants
  • Keep your current phone system and provider
  • Make and receive calls through your existing setup
  • Maintain full control of your numbers
  • Reduce carrier costs by using local VoIP providers with better rates

How It Works

When you integrate your phone system with Autocalls.ai:

  1. Inbound Calls: Calls to your numbers are routed through your phone system to our AI assistants
  2. Outbound Calls: Our AI assistants can make calls appearing from your numbers
  3. Management: You keep managing your numbers through your current provider
  4. Cost Efficiency: Leverage your VoIP provider’s competitive rates for call termination

Integration Options

You can connect your phone system to Autocalls.ai in two ways:

1. PBX Extension Integration

This is like giving our AI platform an “extension” on your phone system:

  • What it is: Connect a specific extension from your PBX/phone system
  • Perfect for:
    • Testing the integration
    • Routing specific extensions to AI
    • Simple setup with existing phone systems
  • You’ll need:
    • Your extension number (e.g., 1000)
    • Extension username and password
    • Your PBX server address (e.g., pbx.yourcompany.com)

Real-world example:

Your office uses extensions 1001-1010 for staff
You set up extension 1011 for the AI assistant
Calls to 1011 go to the AI
The AI can make calls appearing as extension 1011

2. Direct Number Integration

This connects specific phone numbers to our platform:

  • What it is: Route one or more of your phone numbers to our AI
  • Perfect for:
    • Dedicated AI phone lines
    • Customer service numbers
    • Sales or support lines
  • You’ll need:
    • Your phone number (e.g., +1 555 0123)
    • SIP credentials from your provider
    • Provider’s SIP server address

Real-world example:

You have a support number: +1 555 0123
You connect this number to our AI
All calls to +1 555 0123 are handled by the AI assistant
The AI makes outbound calls showing +1 555 0123

Authentication & Call Flow

Bidirectional Configuration

The SIP integration uses the same credentials for both inbound and outbound calls:

  • Inbound Calls (VoIP → Autocalls.ai):

    Your VoIP system authenticates using username/password
    
    Calls reach our platform
    
    AI assistant answers
    
  • Outbound Calls (Autocalls.ai → VoIP):

    AI initiates call
    
    Our platform authenticates to your VoIP using same username/password
    
    Call reaches destination
    

Credential Synchronization

For the integration to work properly:

  1. The credentials you set in Autocalls.ai dashboard must match exactly with your VoIP configuration
  2. The same username/password combination is used for both directions
  3. Any changes to credentials must be updated in both systems

If you change credentials in your VoIP system, remember to update them in Autocalls.ai dashboard (and vice versa) to maintain the connection.

Setting Up Your Integration

Step 1: Gather Your Information

For PBX Extension:

Extension number: e.g., 1000
Server address: e.g., pbx.company.com
Username: Your extension username
Password: Your extension password

For Direct Number:

Phone number: e.g., +1 555 0123
SIP server: e.g., sip.provider.com
Username: Provided by your phone company
Password: Provided by your phone company

Step 2: Configure in Dashboard

  1. Go to your Autocalls.ai dashboard
  2. Navigate to Phone Numbers
  3. Click “Integrate SIP trunk”
  4. Fill in your details based on your integration type

Step 3: Number Format Configuration

This tells our system how to format phone numbers when making calls. Choose based on your provider’s requirements:

  1. International with +

    Format: +[country][number]
    Example: +1 202 555 0123
    SIP Request: sip:+12025550123@your.pbx.com
    
  2. International without +

    Format: [country][number]
    Example: 1 202 555 0123
    SIP Request: sip:12025550123@your.pbx.com
    
  3. National format

    Format: [local number]
    Example: 0741926265
    SIP Request: sip:0741926265@your.pbx.com
    

Step 4: Verify Setup

After configuration:

  1. Make a test call to your number/extension
  2. Check that the AI assistant answers
  3. Use the test call feature to verify outbound calling

Security Requirements

Your SIP credentials need to be secure:

  • Username: Your extension number or provider-supplied username
  • Password must have:
    • 12 or more characters
    • Numbers
    • Upper and lowercase letters
    • Special characters recommended
