CALISTA'S DPCP CONNECTS CISCO'S IP-PBX TO DIGITAL PHONES.Calista, San Jose San Jose, city, United States San Jose (sănəzā`, săn hōzā`), city (1990 pop. 782,248), seat of Santa Clara co., W central Calif.; founded 1777, inc. 1850. , Calif., a provider of gateways that link digital PBXs to IP networks, has created a demonstration program that uses Calista's Digital Phone Control Protocol (DPCP DPCP Display Port Content Protection (Philips) DPCP Digital Phone Control Protocol (Calista) ) to connect Cisco's IP-PBX to proprietary digital telephones. Using the DPCP protocol, Calista's voice over IP products, collectively known as PBXoverIP(TM), can connect a Cisco IP-PBX telephone to legacy PBX (Private Branch eXchange) An inhouse telephone switching system that interconnects telephone extensions to each other as well as to the outside telephone network (PSTN). phones from Lucent, Nortel, Mitel, Siemens, Ericsson, NEC (NEC Corporation, Tokyo, www.nec.com, www.necus.com) An electronics conglomerate known in the U.S. for its monitors. In Japan, it had the lion's share of the PC market until the late 1990s (see PC 98). NEC was founded in Tokyo in 1899 as Nippon Electric Company, Ltd. , and Iwatsu. DPCP allows third party developers to build IP-based PBXs that drive proprietary digital phones using a standard protocol. Calista's DPCP protocol is unique in that it can control a wide variety of digital phones while also interoperating with the standards-based Ethernet H.323 protocol. Calista will be previewing this demonstration at Voice on the Net '99, April 14-16, 1999 in Las Vegas Las Vegas (läs vā`gəs), city (1990 pop. 258,295), seat of Clark co., S Nev.; inc. 1911. It is the largest city in Nevada and the center of one of the fastest-growing urban areas in the United States. , Nevada, at Booth #106. Calista is currently working with IP-PBX developers to add legacy phone support to next generation IP-PBXs. Customers who have an installed base of proprietary digital PBXs will be able to migrate to IP-based systems such as the Cisco IP-PBX, while maintaining the investment they have already made in proprietary PBX phones, wiring, and fault tolerant The ability to continue non-stop when a hardware failure occurs. A fault-tolerant system is designed from the ground up for reliability by building multiples of all critical components, such as CPUs, memories, disks and power supplies into the same computer. power systems. "Calista is thrilled to demonstrate DPCP connecting Cisco's IP call-control to Lucent and Nortel phones," said William MacDonald William Macdonald or MacDonald or McDonald may refer to:

Voice over IP Developer's Kit Calista's voice over IP developer's kit is currently available for next generation PBX manufacturers who want to connect digital PBX phones to an H.323 compliant network. Calista's DPCP protocol will allow them to build products that communicate with the current installed base of proprietary digital telephones. Calista will be adding support for additional digital PBXs throughout 1999. The developer's kit includes sample DPCP code, a sample call control server using DPCP, two PBXoverIP Solo units, and a manual. The price for the kit is $4990. The Evolution of the Next Generation PBX Proprietary digital PBXs, widely in use by corporate America, are very stable but have limitations: modest scalability, complicated user interfaces, and proprietary technology. Due to the increased prevalence of the Internet, vendors are looking to combine voice and data traffic on an IP network. Legacy PBXs will be phased out and replaced by next generation PBXs running over an IP network. An IP-based PBX is completely scalable, provides a standard graphical user interface graphical user interface (GUI) Computer display format that allows the user to select commands, call up files, start programs, and do other routine tasks by using a mouse to point to pictorial symbols (icons) or lists of menu choices on the screen as opposed to having to , and is interoperable among vendors. In addition, an IP-based network can reduce long distance costs and add functionality such as remote user access. About Calista Inc. Calista designs and manufactures business quality devices for connecting PBXs to IP networks, voicemail systems, and call-recording systems. Calista's independently developed digital telephone interfaces are the world's first to provide multi-PBX interoperability with a single piece of hardware. Privately held, Calista is based in San Jose California, Boston, Massachusetts, and Chalfont St. Peter, UK. For more information, call 408-558-9700, ext. 226. |
