商品描述
OpenSER is a flexible, free open-source VoIP server based on the Session Initiation Protocol (SIP), an application-layer control (or signaling) protocol for creating, modifying, and terminating sessions with one or more participants, including internet telephone calls, multimedia distribution, and multimedia conferences.
Engineered to power IP telephony infrastructures up to large scale, OpenSER is written in pure C for Linux/Unix-like systems with architecture-specific optimizations to offer high performance; it is able to handle 4 million users on a single processor server. The server keeps track of users, sets up VoIP sessions, relays instant messages, and creates space for new plug-in applications.
It can be used on systems with limited resources as well as on carrier-grade servers, scaling up to thousands of call setups per second. It is customizable, being able to feature as fast load balancer; SIP server flavors: registrar, location server, proxy server, redirect server; gateway to SMS/XMPP; or advanced VoIP application server.
What you will learn from this book?
- An introduction to SIP
- An overview of SIP Proxies
- Compiling and installing OpenSER
- SIP Proxy default configuration
- Implementing MySQL support for authentication
- Installing the user portal (SerWEB)
- Connecting to the PSTN using a gateway
- Sending a call to voicemail
- NAT traversal using mediaproxy
- Billing with Freeradius and CDRTool
- Troubleshooting tips and tools.
Approach
This book is a well illustrated, step-by-step guide to building a SIP based network using OpenSER.
Who this book is written for?
This book is for readers who want to understand how to build a SIP provider from scratch using OpenSER. Telephony and Linux experience will be helpful but is not essential. Readers need not have prior knowledge of OpenSER.
商品描述(中文翻譯)
詳細內容
OpenSER 是一個靈活的、免費的開源 VoIP 伺服器,基於會話啟動協議 (Session Initiation Protocol, SIP),這是一種應用層控制(或信號)協議,用於創建、修改和終止與一個或多個參與者的會話,包括互聯網電話通話、多媒體分發和多媒體會議。
OpenSER 被設計用來支持大規模的 IP 電話基礎設施,使用純 C 語言編寫,適用於 Linux/Unix 類系統,並進行架構特定的優化以提供高性能;它能夠在單處理器伺服器上處理 400 萬用戶。該伺服器跟蹤用戶,設置 VoIP 會話,轉發即時消息,並為新的插件應用程序創建空間。
它可以在資源有限的系統上使用,也可以在運營商級伺服器上使用,擴展到每秒數千個呼叫設置。它是可定制的,能夠作為快速負載平衡器;SIP 伺服器類型:註冊伺服器、位置伺服器、代理伺服器、重定向伺服器;SMS/XMPP 閘道;或高級 VoIP 應用伺服器。
