Flexible and scalable virtualized SBCs for hosted UC services


Based in Vienna, Communi5 Technologies GmbH is a leading provider of voice application server products. Its unified communications as a service (UCaaS) platform is designed to enable service providers to offer hosted PBX and unified communications services to business and residential customers. In addition to the most important functions for corporate telephony, the UCaaS solution also includes voice messages, conferences, call centers, IVR, collaboration, cross-platform soft clients and seamless mobile integration.

The Communi5 UCaaS solution offers a wide range of options for customer connectivity. Whether dealing with enterprises with existing on-premises IP-PBX or UC solutions looking for SIP trunk connectivity or smaller organizations who rely on the Communi5 platform to offer a fully hosted UC and telephony service, it was critical that all end customers could connect seamlessly and securely to the platform. To achieve this goal, Communi5 required an access session border controller (SBC) that it could offer to its service provider customers as part of the overall solution.

The access SBC Communi5 was looking for had to meet a number of important requirements. These included:

  • A virtualized, software-only product that could be easily deployed at service provider data centers along with the core Communi5 UCaaS solution which itself is a wholly software-based system
  • Highly flexible SIP interoperability to ensure that customers could easily connect to the Communi5 platform regardless of which legacy on-premises solution they were using
  • Rigid security to protect both service providers’ and end customers’ networks and data
  • Support for advanced voice processing technology to ensure high voice quality


  • Seamless connectivity with customers' on-premises platforms

  • Virtualized solution required to fit in with Communi5's infrastructure

  • Robust security mechanisms to protect customer networks and traffic

“The AudioCodes Mediant VE SBC met all of our requirements for a secure, scalable and flexible connectivity solution.”

Thomas Haydn, Managing Director Communi5


Communi5 and AudioCodes had already enjoyed a long and successful business relationship for several years with Communi5 deploying several AudioCodes products in its solutions. While AudioCodes as a company was a trusted vendor from Communi5’s point of view, any SBC solution still needed to be thoroughly tested to ensure that it met all requirements.

After successfully completing a rigorous testing process, AudioCodes’ virtualized, software-only Mediant VE SBC was verified to be deployed as an access SBC with the Communi5 UCaaS solution.

The Mediant VE SBC is a software-only solution meaning that it can fit in with Communi5’s overall approach with its own solution. In addition to delivering broad interoperability and robust security features, the VE SBC is also an extremely scalable solution enabling service providers to start with a small deployment and expand the SBC’s support for concurrent sessions as their service grows. Furthermore, the SBC supports encryption of voice streams without the need to purchase additional licenses or hardware.

The Mediant VE SBC is deployed in a high availability configuration at Communi5’s service provider customers to ensure that it meets the stringent reliability requirements demanded by telecoms operators.
