Voice Solutions

Call. Collaborate. Contribute.


Make it easier, more reliable, and more affordable to get everyone in your organization talking.

As more options become available to carry on business – video, Web collaboration, IM, and social media – it’s easy to forget that the human voice remains a vital and critical form of business communication.

Carrier-grade reliability, simplicity, affordability, and the power to scale to hundreds of thousands of users are all core to our enterprise voice offerings. Voice is a mission-critical application, requiring an incredibly robust voice platform, with built-in redundancies and security features to support real-time communication service levels. There can be no compromise here. Third-party testing hardens our products against the latest security threats. Server pairs can be placed in diverse locations to put your mind at ease and simplify disaster recovery planning. And, no matter what your starting point is today, flexible licensing options help you to transition to the lower costs and flexibility of VoIP in a manner that protects your earlier investment.

Can you expect lower costs? Absolutely. In fact, our customers report an average decrease in the total cost of ownership (TCO) after transitioning to a modern voice infrastructure – by as much as 43% compared with traditional systems. And, with a single management system for all key network applications, you can also lower your energy consumption and costs by up to 30%.

The power of the human voice, combined with a compelling case for cost reduction. With Siemens Enterprise Communications, you’ve found the answer.
