VOIP in Android libraries or sample code

Question

Thanks in advance. I am working on a VOIP application on Android.

Is there any open source code, libraries or sample applications for VOIP software developers to quickly create VOIP applications? Thanks in advance.

In fact, I do not know how to use voip in an Android application. So how to use voip in the application.
