Retarus Chooses Sonus Session Border Controllers To Transform Fax Over IP As-A-Service

Sonus Networks, Inc. (Nasdaq: SONS), a global leader in SIP communications, today announced that Retarus, one of the world’s leading providers of professional messaging solutions, has chosen Sonus session border controllers (SBCs) to help them take advantage of the growing demand for Cloud services, providing Retarus with the opportunity to grow their business and deliver new Internet Protocol (IP)-based services in the future, while protecting their legacy investment today.

Fax remains one of the most relied upon communication methods in enterprises. Headquartered in Germany, Retarus handles more than 600 million fax transactions annually on behalf of its 3,500 customers worldwide. The company chose Sonus SBCs to deliver its fax communications over IP, enabling greater flexibility, advanced capabilities and cost savings without putting the company’s reputation for reliability and quality at risk.

Fax over IP (FoIP) has different requirements to voice over IP (VoIP). Specifically, communications by fax are required to be an exact copy and while Session Initiation Protocol (SIP) simplifies communications, there are many variations of SIP running across carrier networks and these variations can cause challenges on delivering a quality FoIP service offering. Sonus SBCs normalize different versions of SIP across carrier networks with the required quality and security to enable Retarus to have the confidence that their business-critical fax communication services will not be compromised.

The solution for Retarus, featuring the Sonus SBC 5200 and the Sonus SBC 9000, provides advanced integrated media services including T.38 fax relay/internetworking, security, session control, bandwidth management and integrated billing/reporting tools. Retarus selected Sonus SBCs following a thorough and exhaustive proof of concept (POC) during which Sonus demonstrated the robust scalability, flexibility and reliability of the SBC 5200.

The SBC 5200 features industry-leading performance and session capacity with up to 64,000 sessions on a single server. Additionally, the SBC 9000 operates in both a hybrid TDM-IP environment, as well as a pure IP environment, enabling Retarus to leverage their existing TDM network infrastructure. These capabilities have enabled Sonus to be the fastest growing SBC portfolio in the industry.
