SIP Integration

Connect your existing phone system and numbers to Robocallz.ai

Select the country where your SIP trunk is provisioned.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 Robocallz.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 Robocallz.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 Robocallz.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., [phone])
  • SIP credentials from your provider
  • Provider’s SIP server address

Real-world example:

You have a support number: [phone]
You connect this number to our AI
All calls to [phone] are handled by the AI assistant
The AI makes outbound calls showing [phone]

Authentication & Call Flow

Bidirectional Configuration

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

• Inbound Calls (VoIP → Robocallz.ai):

  Your VoIP system authenticates using username/password
  ↓
  Calls reach our platform
  ↓
  AI assistant answers
  
  

• Outbound Calls (Robocallz.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 Robocallz.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 Robocallz.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., [phone]
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 Robocallz.ai dashboard
2. Navigate to Your Phone Numbers
3. Click “Integrate SIP trunk”

Step 3: Select SIP Trunk Type

At the top of the form, select one of these trunk types:

• SIP Extension - Use this if you already have an existing SIP credential (an extension) provided by your VoIP provider.
• Phone Number (DID) - Use this if you want to integrate a dedicated Direct Inward Dial (DID) number instead of a generic SIP extension.

For PBX Extension:

Extension number: e.g., 1000
Username: Your extension username
Password: Your extension password

For Direct Number:

Phone number: e.g., [phone]
Username: Provided by your phone company
Password: Provided by your phone company

Step 4: Outbound Settings

These settings control how Robocallz.ai sends outbound calls through your SIP provider.

• SIP Address - Enter the address/server of the SIP trunk without the port.
• Outbound Proxy (Fixed IP) - Some SIP providers require calls to originate from a single, whitelisted IP address. Configure this as follows:
  • Toggle ON - If your SIP provider requires a fixed source IP, enable Outbound proxy will come from a fixed IP address. Robocallz.ai will then send all outbound requests through a known static IP. Use this option only if your provider explicitly requires a single source IP.
  • Toggle OFF: - If your provider accepts calls from any IP, leave this option off. In that case, Robocallz.ai will send calls from dynamic IPs.

SIP address: (e.g., pbx.company.com/sip.provider.com)

Step 5: 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 +

   Copy

   Format: +[country][number]
   Example: [phone]
   SIP Request: sip:[e-mail]
   
   

2. International without +

   Format: [country][number]
   Example: 1 202 555 0123
   SIP Request: sip:[e-mail]
   
   

3. National format

   Format: [local number]
   Example: 0741926265
   SIP Request: sip:[e-mail]
   
   

Step 6: Inbound Settings

These settings determine how Autocalls.ai receives and authenticates inbound calls from your SIP provider.

1. Our SIP Address - Autocalls.ai assigns a unique inbound SIP URI 5wed79aeavr.sip.livekit.cloud. Your SIP provider must be configured to send inbound calls to this address by pointing their outbound trunk or routing rule to this URI.
2. IP Address (Whitelist IPs) - If your SIP provider can send calls from a known set of public IP addresses, choose IP Address. Then add each provider IP to the whitelist under Inbound Authentication.
3. Username and Password - If your provider supports SIP auth, choose Username and password. The same credentials you entered under Outbound Settings (username/password) will be used to authenticate inbound calls. Make sure your provider’s PBX is configured to include those credentials.

Step 7: Country Selection

Select the country where your SIP trunk is provisioned.

Step 8: 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

Common Questions

Can I use multiple numbers?

Yes! You can integrate multiple extensions or direct numbers with our platform.

Will I lose control of my numbers?

No, you maintain full control through your current provider. The integration only establishes a connection between your system and our platform.

Can I still use my numbers for regular calls?

Yes, you can set up routing rules in your phone system to decide which calls go to the AI and which go to your regular phone system.

What if I need to change settings later?

You can update your integration settings anytime through the dashboard. All configuration options remain accessible after initial setup.

How does this help with call costs?

By using your own VoIP provider, you can take advantage of their local rates and existing agreements, which are often more competitive than standard carrier rates. This is especially beneficial for international calls.
