What Is VoIP?

VoIP is a technology that lets you make voice calls using an internet connection instead of traditional phone lines. It converts your voice into digital signals, allowing you to call anyone with a phone number, whether they’re using a landline, mobile, or another VoIP service. Popular examples include Skype, Zoom, and WhatsApp calls.

Why VoIP?

• Cost Savings: No need for expensive hardware or phone lines.
• Flexibility: Make calls from computers, smartphones, or IP phones.
• Advanced Features: Voicemail-to-email, call recording, and auto-attendants.

How Odoo VoIP Integration Works

Odoo VoIP integration connects your VoIP system directly to Odoo’s ERP platform. This means you can make calls, manage contacts, and track communication history without leaving Odoo. Here’s a step-by-step breakdown of how Odoo VoIP integration works:

5. 5. Use Advanced Features: Set up auto-attendants, call queues, or voicemail based on Odoo data (e.g., route support calls to specific teams).

How Odoo VoIP Integration Works (Step-by-Step)

Let’s break down how Odoo VoIP integration works in a simple way:

Step 1: Install the Odoo VoIP Module

Start by installing the “VoIP” module from the Odoo App store. This is the base for connecting your phone system to Odoo.

Step 2: Choose a VoIP Provider

Odoo works best with providers like Asterisk (open-source PBX system) or cloud-based services like Twilio. You’ll need the following:

• SIP account (Session Initiation Protocol)
• Username and password
• Server IP or domain
• Port details

Tip: If you don’t have an in-house PBX system, Twilio is a user-friendly option to start with.

Step 3: Configure the SIP Settings

Go to the Odoo VoIP settings and input your SIP credentials. Make sure the port and server settings match those of your provider.

Step 4: Enable WebRTC

Odoo uses WebRTC (Web Real-Time Communication) for in-browser calling. Ensure your browser supports it (Google Chrome is recommended).

Step 5: Test Your Connection

After configuring your SIP details, test the connection. Try making a call to a test number or your mobile.

Step 6: Link to CRM or Helpdesk

Once working, you can link your VoIP system with Odoo CRM, Helpdesk, and even the Sales module. Every incoming or outgoing call can be logged against customer records.
