In the evolving landscape of digital communication, businesses are rethinking how they manage voice infrastructure. Traditional PBX systems are costly, inflexible, and difficult to scale. What your business needs is a modern, cloud-native VoIP gateway — one that’s secure, scalable, and simple to manage.
That’s where Opentact steps in. Whether you’re a telecom provider, call center, SaaS platform, or a tech-savvy startup, Opentact transforms your communication stack by giving you full control over VoIP routing, SIP domains, user access, and AI-driven voice automation — all from a single platform.
In this blog, we’ll show you how to set up Opentact as your VoIP gateway and why it’s the smart, scalable alternative to legacy systems.
🌐 What is a VoIP Gateway?
A VoIP gateway is a bridge between traditional telephony (PSTN) and digital voice communication over IP. It enables you to route voice traffic through the internet rather than over expensive landlines.
But not all gateways are created equal. Unlike bulky hardware or clunky open-source setups, Opentact is cloud-native, API-driven, and easy to deploy at scale.
🛠️ Setting Up Opentact as Your VoIP Gateway
Let’s walk through how you can deploy Opentact in your business as a next-gen VoIP solution:

Head to www.opentact.org and create your free account. Once inside the dashboard, you'll gain access to powerful tools to manage voice, SIP, and SMS capabilities — all without writing a single line of code.
✅ Step 2: Create a SIP Domain
Your SIP domain acts as the digital access point for all voice traffic.
Navigate to the SIP Domains section.
Choose a custom subdomain (e.g.,
voice.yourcompany.opentact.org).Define your inbound and outbound routing behavior:
🎯 You can create unlimited SIP domains to manage separate clients, departments, or campaigns.
✅ Step 3: Add SIP Users and Devices
Create SIP user accounts for team members or endpoints:
Assign usernames and passwords
Use these credentials on:
✅ Bonus: Internal calls between SIP users are completely free — saving thousands on communication costs.
