需要Python 2.7及以上版本，以及Python SWIG模块。要使用应用程序，只需运行：
python application.py
9.1.3 安卓
请参考 https://trac.pjsip.org/repos/wiki/Getting-Started/Android#pjsua2 的示例应用程序。
9.1.4 Java
在目录 pjsip-apps/src/swig/java 下有一个Hello World类型的应用程序。
需要Java SWIG模块。构建SWIG模块后，从该目录运行该应用程序。
make test
9.1.5 iOS
可拷贝 pjsip-apps/src/samples/pjsua2_demo.cpp 的代码（即本页第一个代码段中的代码）到 .mm文件中，然后加入到 iOS XCode项目中。
注意：必须使用Obj-C ++（.mm）文件，而不是默认的Obj-C（.m）文件
