"With our new agreement, Black Box will continue to expand its installed Siemens customer base throughout the United States and Canada." Black Box will continue to sell and support the complete portfolio of Siemens communications solutions. This includes HiPath Real-Time IP systems - for organizations of all sizes - providing centralized control of features, access, configuration and call-processing functions. The Siemens portfolio also includes HiPath Wireless, secure and mobile management solutions for voice over wireless LAN networks. In addition, HiPath solutions include the DirX(R) family of access and data management systems, the optiPoint family of IP and wireless phones, the ProCenter(R) portfolio of contact center solutions, the Xpressions(R) unified messaging family and the HiPath OpenScape(TM), a presence-enabled and permission-based unified communication portal.
