c++ - 如何从 pjsip 发送电子邮件。是否有任何默认方法可用于发送电子邮件

Question

我有一个用于调用应用程序的 pjsip 项目。我有一个外部包，如 curl。是否可以将外部包添加到 pjsip 应用程序或如何将外部包添加到 pjsip。是否有任何默认方法可用于发送电子邮件。我想检查这些东西。请帮助解决我的问题。提前致谢。

我想在设备注册失败时从 pjsip 发送一封电子邮件。

Answer 1

我已经为电子邮件发送创建了单独的项目，并将该项目包含在 pjsip 项目中。即我已经包含头文件并从 pjsip 中的设备注册失败案例调用我的函数。我认为这种解决方案更好。我认为没有其他选项可以使用 pjsip 的内置函数发送电子邮件。

1. 创建了单独的项目。
2. 将项目包含在 Visual Studio 解决方案资源管理器中。
3. 在pjsip中包含头文件
4. 在设备注册失败的情况下从项目中调用我的方法。
