Computer Software Telephony

The insider's guide to IP-based telephony: development, network deployment, testing, and beyond Now that virtually every leading telecommunications service provider has committed to delivering IP-based telephony services, communications professionals face the enormous challenge of implementation. This hands-on guide brings together today's best-known answers and solutions for delivering Voice Over IP (VoIP) services with the quality customers demand. No other book covers the combined issues of protocol signaling, media transport methodology, reference topological considerations, and voice quality testing in service offerings. Bill Douskalis presents systematic coverage of every aspect of IP-based telephony: Coverage includes: A realistic reference topology for implementing and benchmarking voice quality in IP telephony Detailed explanations of call setup using each major competing technology Signaling, bearer transport, and other key network elements In-depth network and service performance analysis in both "normal" and impaired scenarios State-of-the-art traces and performance measurements taken from actual IP networks No matter what your role in delivering VoIP services, IP Telephony delivers the specifics you need to speed deployment, improve reliability, ensure quality, and simplify troubleshooting. Precise, thorough, and based firmly in the real world, it is simply indispensable. The accompanying CD-ROM contains Hewlett-Packard Internet Advisor software that runs off-line--view live VoIP traffic examples! It also includes sample capture files of the H.323, MGCP, and SIP protocols; the latest IETF Working Group documents for VoIP; and an assortment of whitepapers and application notes that provide a real-world view of IP telephony.

"The solid technology underlying the Series 60 Platform provides mobile software developers with a great opportunity for mobile software innovation. The latest technologies and open standards offered by the Series 60 Platform provide great possibilities to create world-class applications. The user interface and application set provides a host of reusable components that can make an application attractive and easy to use." Jouko Hä yrynen, Vice President, Forum Nokia. Visit the associated websites at: www.symbian.com/books www.digia.com www.wileyeurope.com The Series 60 platform, designed for Symbian OS, supports mobile browsing, multimedia messaging service (MMS) and content downloading, as well as many personal information management (PIM) and telephony applications. The exploding market in Symbian OS smartphones means that understanding the key technologies and unique characteristics of programming for embedded devices will be vital in building the applications and services of the future. "Programming for the Series 60 Platform and Symbian OS, written by software professionals at Digia, provides the reader with a complete overview of the Series 60 Platform and its software, and explains the best development practices with numerous examples covering: software design and tools GUI framework, UI components and UI customization communications and messaging interfaces for MMS, SMS, e-mail, smart messaging, Bluetooth, IrDA, and TCP/IP User Experience and Interaction Design Java MIDP application development This invaluable handbook will help experienced C++ and Java programmers develop their knowledge of the Series 60 Platform and Symbian OSprogramming. It will also provide managers, testers and designers with valuable information on architecture interfaces, tools, user experience, and testing.

Computer software - Computer software (or simply software) is that part of a computer system that consists of encoded information (or computer instructions), as opposed to the physical computer equipment (hardware) which is used to store and process this information. The term is roughly synonymous with computer program but is more generic in scope.

Computer-aided software engineering - Computer-aided software engineering (CASE) is the use of software tools to assist in the development and maintenance of software. Tools used to assist in this way are known as CASE Tools.

3D computer graphics software - 3D computer graphics software is a program or collection of programs used to create 3D computer-generated imagery.

Computer telephony integration - Computer telephony integration (CTI) is technology that allows interactions on a telephone and a computer to be integrated or co-ordinated.
