Session Border Controller as a Service (SBCaaS)

Create a more agile, resilient and centrally
managed approach to your network.

Centrally manage and secure your voice and video communications.

VoIP and Unified Communications solutions have made your business more connected and efficient. But delivering these solutions traditionally meant investing in purpose-built appliances and proprietary software licenses for each location. Aside from the considerable upfront investment, installing new circuits could take you weeks, followed by days of burdensome configuration.

Our Virtual Network Services (VNS) - Session Border Controller as a Service (SBCaaS) solution gives you a more agile, centrally managed approach to network deployments and management. When combined with Enterprise Orchestration, it lets you deliver communications quickly and flexibly 24x7, and manage seasonal demand surges without investing in new equipment. And it’s all orchestrated by our experts, with over two decades of experience managing customer networks.

What is VNS - SBCaaS?

A Session Border Controller is a policy-based voice and video solution that lets enterprises securely deploy IP-based real-time communications services like VoIP and unified communications. It also acts as a first line of defense against a range of cyber-attacks, including service theft, spoofing and DDoS.


How does VNS - SBCaaS work?

VNS - SBCaaS is like a traffic cop for your SIP sessions, securing and managing activity across your network. The solution connects your voice, video and instant messaging services and securely delivers them across both public and private networks. And since it’s fully managed and hosted, we handle the configuration and management.
