NFON SIP Trunk is a cloud-enabled telephony gateway that helps businesses transition smoothly from legacy PBX setups to modern, IP-based communications. By leveraging VoIP technology and NFON’s carrier network, it connects your existing phone systems—including on-premises PBXs or Microsoft Teams—to the public telephone network and cloud services without needing hardware replacements. Benefits & Features Effortless transition: Maintain your current PBX hardware and phone infrastructure while gaining the flexibility of cloud-based telephony. You decide when and how to introduce additional features. - Scalable and cost-effective: Consolidate voice and data networks to reduce maintenance costs. Easily scale call volume and branch connectivity, and take advantage of competitive telephony tariffs. - Full control via self-service portal: Configure your SIP trunks independently using an intuitive web portal—manage number blocks, routing, and external call blocking all in one place. - Security, high availability & resilience: Protect your communications with features like call-blocking and fraud detection. High availability is built in via load distribution and backup systems across PBXs, ensuring uninterrupted service. - Flexible number routing: Assign phone numbers dynamically from one number block to multiple PBX endpoints—no need to purchase new blocks, lowering cost and complexity. - Seamless integrations: Connect SIP Trunk to modern tools like Microsoft Teams (via Direct Routing or Operator Connect) and contact-center platforms (e.g., Genesys Cloud), enabling unified telephony across systems. Best Practices in the Industry - Preserve existing infrastructure while evolving: By acting as a bridge to IP telephony, businesses avoid unnecessary hardware refreshes and preserve return on prior investments. - Modular, pay-as-you-go model: Subscription-based flexibility aligns spending with actual usage, supporting both conservative budgets and scaling operations. - Built for remote and hybrid workflows: Integration with UC tools and centralized management allows distributed teams to stay connected without friction. - Operational resilience through redundancy: Load balancing across backup PBXs ensures consistent service, even during infrastructure interruptions. - Self-management for speed and efficiency: Empowered via self-service portals, IT teams can quickly adjust routing, settings, and numbers without vendor dependencies.
