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:- Inbound Calls: Calls to your numbers are routed through your phone system to our AI assistants
- Outbound Calls: Our AI assistants can make calls appearing from your numbers
- Management: You keep managing your numbers through your current provider
- 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)
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
Authentication & Call Flow
Bidirectional Configuration
The SIP integration uses the same credentials for both inbound and outbound calls:-
Inbound Calls (VoIP → Autocalls.ai):
-
Outbound Calls (Autocalls.ai → VoIP):
Credential Synchronization
For the integration to work properly:- The credentials you set in Autocalls.ai dashboard must match exactly with your VoIP configuration
- The same username/password combination is used for both directions
- 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.
