The inbound service
Inbound Services are centered on the power of constant availability. This feature transforms your AI agent into a sophisticated, round-the-clock receptionist capable of answering queries, booking appointments, or routing tickets the moment a customer dials your number. It serves as a digital front desk that remains perpetually alert, ensuring your business provides a professional and consistent response to every caller, regardless of the hour.
Technical Connectivity
To bring your AI agents online for incoming calls, you must establish a secure technical link between your telephony provider and the Nabrah platform. This integration ensures that every call is routed with high fidelity and verified security.
The foundation of our inbound service is based on Direct SIP URI Routing. This method allows your existing infrastructure to point calls directly to our platform’s processing engine. To maintain a secure environment and prevent unauthorized access, the integration utilizes Digest Authentication. This challenge-response mechanism ensures that every incoming session is validated before the AI agent answers.
Firewall and Network Configuration
To ensure a high-quality, uninterrupted voice connection between your telephony infrastructure and Nabrah, your network environment must be configured to allow specific traffic. These settings prevent dropped calls and ensure the AI can "hear" and "speak" with minimal latency.
Connectivity Requirements
Please configure your firewall and network routing to support the following parameters:
Component | Protocol | Port Range | Direction |
|---|---|---|---|
SIP Signaling | UDP(Dedault) | 5060 | Bi-Directional |
RTP Media | UDP | 10000-20000 | Bi-Directional |
Creating an Inbound Service
To enable your AI agent to receive incoming calls, you must configure a dedicated inbound service. This process links your telecommunication infrastructure to the Nabrah platform, allowing for seamless call routing and automated handling.
Step 1: Access Inbound Management Navigate to the Inbound Service section via the main sidebar. Once in the dashboard, click the "Create Inbound Service" button to open the configuration window.

Step 2: Configure Service Parameters Fill in the following fields to establish the connection. These details ensure that the platform recognizes incoming traffic and routes it to the correct agent.
Field | Requirement | Description |
Service Name | Mandatory | A unique name for your internal reference (e.g., "Main_Support_Line"). |
Phone Number | Mandatory | The DID (Direct Inward Dialing) number assigned to this service. |
IP Number | Optional | The IP address of your SIP gateway or PBX sending the traffic. |
Username | Optional | The digest authentication username if your SIP URI requires it. |
Password | Optional | The digest authentication password for secure handshake verification. |
Step 3: Linking the Agent Once the fields are populated and saved, your selected agent is officially linked to the inbound service. The agent will now automatically trigger its defined greeting and logic whenever a call is received on the configured DID.
