Tutorials(教程)


 1.Basic buddy status notification (基本的好友状态通知)

    这个程序是一个非常简单的liblinphone用例,演示如何发起SIP订阅和接收来自sip uri标识（从命令行传递的）的通知.

    参数必须像 sip:jehan@sip.linphone.org        

    例如 budy_list sip:jehan@sip.linphone.org

    订阅在SIGINT上清除

 2.Chat room and messaging (聊天室和消息传递)

    这个程序是一个liblinphone的一个非常简单的用例,演示如何发送/接收来自一个sip uri标识的SIP消息.

    参数必须像 sip:jehan@sip.linphone.org.

    例如 chatroom sip:jehan@sip.linphone.org

4.Generic subscribe/notify example(通用的订阅/通知例子)

   这个程序是一个非常简单的liblinphone用例.它演示了如何监听一个SIP订阅.然后定期发送通知请求.第一个参数必须像 sip:jehan@sip.linphone.org,第二个参数必须是密码.

   例如 registration sip:jehan@sip.linphone.org 密码

   注册在SIGINT上清除

7.Basic registration（基本的注册）

    这个程序是一个非常简单的liblinphone用例.演示如何从一个sip URI（由命令行传递的）发起一个SIP注册.第一个参数必须像 sip:jehan@sip.linphone.org, 第二个参数必须为密码.

   例如 registration sip:jehan@sip.linphone.org 密码

   注册在SIGINT上被清除.
