OpenSIPS is a multifunctional, multipurpose signalling SIP server. SIP (Session Initiation Protocol) is nowadays the most important VoIP protocol and OpenSIPS is the open source leader in VoIP platforms based on SIP. OpenSIPS is used to set up SIP Proxy servers. The purpose of these servers is to receive, examine, and classify SIP requests. The whole telecommunication industry is changing to an IP environment, and telephony as we know it today will completely change in less than ten years. SIP is the protocol leading this disruptive revolution and it is one of the main protocols on next generation networks. While a VoIP provider is not the only kind of SIP infrastructure created using OpenSIPS, it is certainly one of the most difficult to implement.This book will give you a competitive edge by helping you to create a SIP infrastructure capable of handling tens of thousands of subscribers.Starting with an introduction to SIP and OpenSIPS, you will begin by installing and configuring OpenSIPS. You will be introduced to OpenSIPS Scripting language and OpenSIPS Routing concepts, followed by comprehensive coverage of Subscriber Management. Next, you will learn to install, configure, and customize the OpenSIPS control panel and explore dialplans and routing. You will discover how to manage the dialog module, accounting, NATTraversal, and other new SIP services. The final chapters of the book are dedicated to troubleshooting tools, SIP security, and advanced scenarios including TCP/TLS support, load balancing, asynchronous processing, and more.A fictional VoIP provider is used to explain OpenSIPS and by the end of the book, you will have a simple but complete system to run a VoIP provider.

Until recently, writing applications using JavaScript and HTML was difficult, because developers had to make the user interface by themselves; however, this started changing with the introduction of JavaScript libraries such as jQuery, jQuery UI, and KnockoutJS. An extension of jQuery UI, Wijmo adds features and widgets on top of jQuery UI and makes it easier to add user interface widgets to HTML documents.Building UIs with Wijmo gives you a tour of what Wijmo offers at a glance. With code recipes and well-explained examples, you will be able to use Wijmo in no time. The book gives details on options not explained in the documentation and helps you avoid those that don't work. The examples only feature the necessary code, with recommendations and best practices.This book introduces Wijmo, grouping widgets by their common application area or usage. It walks the user through the features of the dialog widget with examples as an introduction to the library. Then, widgets for forms, images, tootips, and other topics are explored.Features only available in the Wijmo dialog widget compared to the jQuery UI widget are thoroughly explained with examples. Common form components such as checkboxes, dropdowns, and inputs have Wijmo counterparts which keep the theme consistent and add functionalities. When Wijmo is used with Knockout, the UI automatically refreshes when the data changes. This book takes it further with WebSockets for two way communication between the server and client. With Building UIs with Wijmo, you will learn all the common web development components in Wijmo. You will get started using Wijmo in no time.

The ArcGIS API for JavaScript enables you to quickly build web and mobile mapping applications that include sophisticated GIS capabilities, yet are easy and intuitive for the user.Aimed at both new and experienced web developers, this practical guide gives you everything you need to get started with the API. After a brief introduction to HTML/CSS/JavaScript, you'll embed maps in a web page, add the tiled, dynamic, and streaming data layers that your users will interact with, and mark up the map with graphics. You will learn how to quickly incorporate a broad range of useful user interface elements and GIS functionality to your application with minimal effort using prebuilt widgets. As the book progresses, you will discover and use the task framework to query layers with spatial and attribute criteria, search for and identify features on the map, geocode addresses, perform network analysis and routing, and add custom geoprocessing operations. Along the way, we cover exciting new features such as the client-side geometry engine, learn how to integrate content from ArcGIS.com, and use your new skills to build mobile web mapping applications.We conclude with a look at version 4 of the ArcGIS API for JavaScript (which is being developed in parallel with version 3.x) and what it means for you as a developer.
