Pingtel xpressa IP Phone Software Release 2 Offers New Features And Enhanced Voice Quality, Including Global IP Sound Technology.Business/Technology Editors Pingtel(R) today announced Release 2 software for Pingtel xpressa(TM) desk phones and instant xpressa(TM) softphones, the world's first IP phones to exploit the Session Initiation Protocol (protocol) Session Initiation Protocol - (SIP) A very simple text-based application-layer control protocol. It creates, modifies, and terminates sessions with one or more participants. Such sessions include Internet telephony and multimedia conferences. It is described in RFC 2543. (SIP) standard and Java programming environment. The new Pingtel xpressa software offers many new user features, including multi-line operation, support for multiple incoming calls, dialing from Microsoft Outlook For the e-mail and news client bundled with certain versions of Microsoft Windows, see . Microsoft Outlook or Outlook (full name Microsoft Office Outlook , easier phone management and increased security features as well as enhanced audio quality, including SoundWare(TM) from Global IP Sound. Release 2 multi-line operation offers a level of flexibility that is not possible with traditional 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). or Centrex phone service. For example, a single xpressa phone can be connected to multiple IP PBXs (Internet Protocol Private Branch eXchange) A telephone switch that supports voice over IP (VoIP). IP PBXs convert IP phone calls into traditional circuit-switched TDM connections for the PSTN. or IP Centrex A telephone service in which an IP-based PBX is located in the telephone company's facilities. It connects to the customer via the LAN rather than by telephone wires. IP CENTREX offers voice over IP and other IP-based services as well as connectivity to the regular telephone system (PSTN). services, so one phone can offer an internal phone number and line, an external number and line, and a line for low-cost long-distance calling, as well as many other combinations of numbers and lines. Multi-line operation also permits a phone to receive calls for multiple extensions, people or office groups. For example, a phone can offer both a personal line and a shared line, which could be answered by anyone in a particular group. The new software also gives phone users an enhanced ability to handle multiple inbound calls at the same time. The phone will notify users when they receive multiple calls, display the number of incoming calls on the LCD screen, and let users answer or ignore each of the incoming calls. Release 2 software provides new integration between the xpressa phone and Microsoft Outlook. With a new software add-in, Click-to-Dial from Outlook, phone users can easily dial numbers in their Outlook contact list by simply clicking on the xpressa icon in Outlook. The integration with Outlook is another example of the exciting types of desktop computer telephony integration Computer Telephony Integration - Computer Telephone Integration (CTI (Computer Telephone Integration) Combining data with voice systems in order to enhance telephone services. For example, automatic number identification (ANI) allows a caller's records to be retrieved from the database while the call is routed to the appropriate party. ) that are enabled by the phone's ability to create a peer-to-peer relationship between a user's xpressa phone and their computer. "The new xpressa software provides a number of features that I particularly like, such as the multi-line capability that allows me to set up my manager's phone so he can answer my line when I'm not available," said Clifton Jones Clifton Jones (born 1942, Jamaica) is an actor, mostly known for his roles on British television. His most prominent role is probably that of David Kano during the first season of the science fiction series . , a senior software engineer at LongBoard A longboard generally designates a longer board variant in various .
Release 2 uses the latest compression and audio-enhancing techniques to offer superlative voice quality. Among the audio enhancements is new technology licensed from Global IP Sound (www.globalipsound.com). By incorporating the GIPS GIPS - /gips/ or /jips/ [Analogy with MIPS] Giga-Instructions per Second (or possibly "Gillions of Instructions per Second"; see gillion). In 1991, this was used of only a handful of highly parallel machines and one sequential processor built with Josephson devices. SoundWare(TM) solution, which includes GIPS Enhanced G711 and NetEQ(TM), Pingtel xpressa and instant xpressa now have an advanced adaptive jitter A flicker or fluctuation in a transmission signal or display image. The term is used in several ways, but it always refers to some offset of time and space from the norm. For example, in a network transmission, jitter would be a bit arriving either ahead or behind a standard clock cycle buffer control for significant latency savings and an advanced error concealment algorithm to compensate for packet loss problems. "Pingtel xpressa has consistently been a leading innovator in IP phone technology," said Roar Hagen, chief technology officer, Global IP Sound. "Inclusion of our SoundWare solutions establishes Pingtel as a leader in IP phone voice quality too." In addition to solving many of the jitter, latency and packet loss problems that have impeded IP telephony The two-way transmission of voice over a packet-switched IP network, which is part of the TCP/IP protocol suite. The terms "IP telephony" and "voice over IP" (VoIP) are synonymous. , Global IP Sound also assisted Pingtel in building upsampling and downsampling digital signal processing See DSP. Digital Signal Processing - (DSP) Computer manipulation of analog signals (commonly sound or image) which have been converted to digital form (sampled). filters that minimize distortion when converting voice calls from the phone's high internal sampling rate to the legacy telephone network's lower rate. The Pingtel xpressa phone also uses voice activity detection, silence suppression Encoding the start and stop times of silence (lack of voice) in order to eliminate wasted bandwidth when sending voice over a packet-switched system. and comfort noise generation to improve the audio experience. The new software release delivers stellar speakerphone audio quality by incorporating advanced acoustic echo cancellation The elimination of an echo in a two-way voice transmission. Echo is created in the telephone company's central office switch when two-wire lines from the customer are converted to four-wire lines for backbone trunks. software developed by Pingtel. Utilizing sophisticated multi-band cancellation techniques, the Pingtel xpressa phone now provides world-class full-duplex audio, where both sides of a speakerphone conversation can talk simultaneously without one party becoming automatically muted. "Release 2 further advances the state of IP telephony by delivering new productivity-enhancing features and exceptional voice quality," said Jay Batson, chief executive officer and co-founder, Pingtel. "The dramatic improvement in voice quality and many new user benefits is another tribute to our ability to quickly add new technology and features without the traditionally long planning, development and testing cycles." Release 2 also helps increase system security and simplify phone management. The software offers increased security by using the Digest Access Authentication HTTP Digest access authentication is one of the agreed methods a web page can use to negotiate credentials with a web user (using the HTTP protocol). Digest authentication is intended to obsolete unencrypted use of the Basic access authentication, allowing user identity to be Scheme to ensure message integrity, avert replay attacks and prevent passwords from being sent without protection. Service providers and enterprise telecom managers will benefit from a new VersionCheck software update mechanism that provides flexible control over which version of Pingtel software is deployed on the phones they administer. And Release 2 also provides enhanced support for digit map variables that can help modify SIP addresses by correctly handling extra digits, such as the 9 that many users have to dial to get an outside line.
