Siemens Enterprise Communications Turns to Acme Packet Net-Net E-SBCs for Global UC Deployment

Siemens Enterprise Communications is a global leader in end-to-end enterprise unified communications and collaboration (UCC) solutions. The company’s award-winning OpenScape product family delivers comprehensive communication and collaboration functionality for organizations of all sizes.

The company operates major R&D facilities in Germany, USA and Brazil; has a presence in more than 90 countries; and employs 10,000+ employees around the world. They planned to replace their legacy TDM telephony network with a global IP private cloud-based communications infrastructure to improve collaboration, increase workforce productivity and reduce communications expenses and sought a session border control solution to address SIP security, interoperability and reliability concerns.

After a rigorous evaluation process, the company selected and deployed Acme Packet Net-Net Enterprise Session Border Controllers (E-SBCs) to protect and control their private and public IP network borders. Siemens Enterprise Communications now enjoys a more efficient and cost-effective IP communications network that allows employees to leverage all the features and benefits of the OpenScape unified communications product portfolio—anywhere, anytime.

Business Challenge

A word from Siemens Enterprise Communications

  • “By implementing SIP trunking and Acme Packet Net-Net E-SBCs, Siemens Enterprise Communications was able to reduce PSTN access costs by over 60% without sacrificing security or reliability.” - Raik Miercke Global Voice Service Manager, Siemens Enterprise Communications

Like many global enterprises, Siemens Enterprise Communications historically relied on the PST and a legacy TDM-based telephony network for internal and external communications. The company planned to implement a global IP communications network based on a private-cloud to improve collaboration, reduce expenses and showcase its OpenScape solutions and OpenSmart best practices approach.

Siemens Enterprise Communications’ existing IP networking infrastructure was not designed to support SIP-based communications and would have left the company vulnerable to security threats and service quality issues. The company sought a session border control solution to mitigate multi-vendor interoperability and multi-protocol interworking challenges, safeguard user confidentiality and privacy, and ensure service quality and integrity.
