Mobicents SIP Servlets的Click2Call实例实践
简介：Mobicents是一个大型开源的VoIP中间件平台，SIP Servlets是其中的一个重要组件。本文主要介绍SIPServlets的环境搭建及调测其中的Click2Call例子。Call2Call实际上是通过Web方式以一个第三方的角色来将两个用户之间的对话建立起来。
测试环境准备：准备好同时带有麦克风和耳机的两台电脑，并保证他们在网络上能够互通。
第一步：下载Mobicents SIP Servlets。进入主页http://code.google.com/p/sipservlets/。这里选择最新的稳定版本1.7，网址为http://sourceforge.net/projects/mobicents/files/Mobicents%20Sip%20Servlets/Mobicents%20Sip%20Servlets%201.7.0.FINAL/， 这里有5个包，主要包含jboss和tomcat两个版本。这里以jboss版本为例，因为tomcat版本的功能不如jboss全。请选择mss-1.7.0.FINAL-jboss-jdk6-5.1.0.GA-1204061650-full.zip，大约168.30M。
第二步：部署Mobicents SIP Servlets。
下载完成后，解压。在windows下开启cmd窗口进入解压后的包的bin目录，然后运行run.bat-b 10.50.24.61(这个地址可以根据你本机的IP地址来配置)运行。等JBOSS启动完毕之后，在浏览器中输入http://10.50.24.61:8080/sip-servlets-management/可以查看一些配置。输入http://10.50.24.61:8080/click2call/可以进入click2call的测试页面。
第三步：准备SIP客户端1。这里以SJphone为例。请从http://www.sjlabs.com/sjp.html下载windows版本，然后安装完成并启动。
点击Menu->Options在弹出的对话框中选择Profiles选项卡，点击new打开”CreateNew Profile”的窗口。在ProfileName中填入Dennis，其他默认即可。然后在返回的ProfileOptions中选中SIPProxy选项卡中的Domain/Realm中填入10.50.24.61:5080.再打开SIPRegistration选项卡，去掉”Unregisteronly registered contact”并选中”Useseparate Registrar”，并在Registrar(URI)中填入sip:10.50.24.61:5080，然后点击OK。最后在弹出的”Service:Dennis”中输入Account：Dennis，Password:123456。然后点击OK，系统会自动进行注册。
特别注意：这里的账户可以随意填写，不需要事先在服务器端进行配置。
以上步骤都是在电脑1上面完成。下面的步骤在电脑2上完成。
第四步：准备第二个SIP客户端。将SJphone在第二台电脑上安装好。安装上面的配置分别将改为Terry即可。
第五步：呼叫测试。现在刷新http://10.50.24.61:8080/click2call即可看到已经注册成功的两个SIPUser Agent。然后点击对应的call按钮即可将两个用户的通话建立起来。通话质量还不错。
后记：最近需要做一个基于SIP的通信系统，Mobicents是一个研究的对象。这里及时将一些所得记录一下，一方面希望能给一起研究Mobicents的朋友有所帮助，另一方面也是记录备以后差用。

When might a full table scan be faster than using an index in MySQL?
Apr 09, 2025 am 12:05 AM
Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.
Can I install mysql on Windows 7
Apr 08, 2025 pm 03:21 PM
Yes, MySQL can be installed on Windows 7, and although Microsoft has stopped supporting Windows 7, MySQL is still compatible with it. However, the following points should be noted during the installation process: Download the MySQL installer for Windows. Select the appropriate version of MySQL (community or enterprise). Select the appropriate installation directory and character set during the installation process. Set the root user password and keep it properly. Connect to the database for testing. Note the compatibility and security issues on Windows 7, and it is recommended to upgrade to a supported operating system.
Explain InnoDB Full-Text Search capabilities.
Apr 02, 2025 pm 06:09 PM
InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.
Difference between clustered index and non-clustered index (secondary index) in InnoDB.
Apr 02, 2025 pm 06:25 PM
The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values and pointers to data rows, and is suitable for non-primary key column queries.
MySQL: Simple Concepts for Easy Learning
Apr 10, 2025 am 09:29 AM
MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.
The relationship between mysql user and database
Apr 08, 2025 pm 07:15 PM
In MySQL database, the relationship between the user and the database is defined by permissions and tables. The user has a username and password to access the database. Permissions are granted through the GRANT command, while the table is created by the CREATE TABLE command. To establish a relationship between a user and a database, you need to create a database, create a user, and then grant permissions.
Explain different types of MySQL indexes (B-Tree, Hash, Full-text, Spatial).
Apr 02, 2025 pm 07:05 PM
MySQL supports four index types: B-Tree, Hash, Full-text, and Spatial. 1.B-Tree index is suitable for equal value search, range query and sorting. 2. Hash index is suitable for equal value searches, but does not support range query and sorting. 3. Full-text index is used for full-text search and is suitable for processing large amounts of text data. 4. Spatial index is used for geospatial data query and is suitable for GIS applications.
Can mysql and mariadb coexist
Apr 08, 2025 pm 02:27 PM
MySQL and MariaDB can coexist, but need to be configured with caution. The key is to allocate different port numbers and data directories to each database, and adjust parameters such as memory allocation and cache size. Connection pooling, application configuration, and version differences also need to be considered and need to be carefully tested and planned to avoid pitfalls. Running two databases simultaneously can cause performance problems in situations where resources are limited.
