TelcoBridges Expands Session Border Controller Portfolio with General Availability Release of ProSBC 3.1

Feature-Rich, Virtual SBC Software Delivers new Capabilities that Enable a Wide Range of Use-Cases for Service Providers and Enterprises

Montreal, Canada: August 01, 2019 – TelcoBridges, the leading designer and manufacturer of carrier-grade virtual session border controller software and Tmedia VoIP gateways, today announced that it has extended its product portfolio through the general availability release of ProSBC, a feature-rich Virtual Session Border Controller for Service Providers and Enterprises.

ProSBC features a number of significant enhancements over the existing FreeSBC edition, including:
• Encrypted SIP/TLS signaling and SRTP media relay features
• Enhanced high availability features, supporting no loss-of-calls during a fail-over
• Permanent licenses – at additional cost, eliminating annual license key updates
• Support for the Microsoft Azure cloud
• An improved web portal user interface.

Beyond this initial GA release, TelcoBridges is planning additional enhancements for ProSBC as part of an ongoing development roadmap, which has been fueled by customer feedback and market demand.

“Strong uptake of the company’s FreeSBC product over the past 18 months has validated the need for new vSBC business models, and has expanded TelcoBridges’ addressable market significantly within the service provider and enterprise segments,” said GlobalData Analyst John Byrne. “The company’s new ProSBC product enables TelcoBridges to continue to offer vSBC solutions to a growing number of edge use-cases while maintaining a very low cost-of-entry advantage that has attracted customers to the FreeSBC product.”

“ProSBC 3.1 GA offers many new capabilities that enable a wide range of additional use-cases,” said TelcoBridges’ Chief Marketing Officer Alan Percy. “The positive feedback we’ve gotten from the Beta community indicates that ProSBC will fulfill the needs of the wider service provider and enterprise markets.”
