BROADSOFT AND SIEMENS DELIVER SIP INTEROPERABILITY

Interoperability between BroadSoft's BroadWorks and Siemens optiPoint 100 advance telephone broadens access choices available to enterprises and furnishes service providers with the means to rapidly deliver new telephony services for expanded market penetration.

The addition of SIP functionality extends the capabilities of Siemens award-winning optiPoint telephone product line, already available with H.323, H.450 and Siemens own HFA (Hicom Feature Access) protocol support. Reliable as well as robust, this family of telephones is modular, feature-rich and easy to upgrade, even from a remote location. The optiPoint IP phones are available globally through Siemens distributors and resellers.

"As service providers evolve their business telephony services to meet customer demands for the more innovative and cost-effective services enabled by IP technology, users will benefit from Siemens telephone and telephony experience, which is far more extensive than other IP telephone manufacturers," said Bob Thompson, vice president of HiPath corporate solutions for Siemens. "By achieving interoperability, BroadSoft and Siemens deliver on the promise of open standards in voice communications."

BroadWorks is the industry's first complete service delivery system that enables service providers to offer a rich set of web-enabled user-friendly enhanced telephony services. BroadWorks' platform cuts across circuit and packet technologies, allowing service providers to roll out packet-based telephony services with incremental investment to their network infrastructure. The BroadWorks services portfolio includes Centrex services such as call waiting, conferencing and voice mail, auto-attendant and follow-me-anywhere services; new services such as instant messaging; and integration with key business tools such as Outlook and Palm OS-based hand-held devices. These services can be customized and managed via BroadWorks' web-based portal, CommPilot™ , which provides an alternative user interface for enhanced services, replacing the flash-hook and star codes of a standard phone.

"BroadSoft's interoperability with Siemens optiPoint 100 advance telephone is good news for business users," said Scott Wharton, vice president of marketing at BroadSoft. "The optiPoint 100 advance telephone is the ideal desktop complement to our BroadWorks system and its media-oriented applications, such as conferencing, voice mail, auto-attendant and other IVR applications, and we are pleased to be working with Siemens to transform the way telephony services are provided and consumed."

The optiPoint 100 advance is available today and can be ordered from the following distributors: Ingram Micro (www.ingrammicro.com), Tech Data (www.techdata.com), Target Distributing (www.targetd.com), and DistributorWorks, LLC (www.distributorworks.com.)
