これは、サンプルコードを含むサードパーティのライブラリです。あなたはこれを使うことができます、私はそれを使いました、そしてそれはうまく働きます。

android 4.0.3 SDKバージョン（APIレベル-15）のサンプルでSipDemoプロジェクトを検索します

私はこの種の問題を長い間調査してきましたが、SipManagerとSipProfileは残念ながら貧弱で、非常にバグがあることがわかりました。
そこで、Linphoneライブラリを見つけました。彼らのウィキへのリンクがあります。私はmavenを使用してプロジェクトに実装しました：
repositories {
...
maven { "https://linphone.org/maven_repository/"}
}
また、gitlabでそれを使用するサンプルがあります：ここにリンクしてください、それは今のところかなり新鮮です:)
リンクがクラッシュした場合は、 linphoneのコアの使用方法の最も重要な部分をコピーして貼り付けます。
public class LinphoneService extends Service {
private static final String START_LINPHONE_LOGS = " ==== Device information dump ====";
// Keep a static reference to the Service so we can access it from anywhere in the app
private static LinphoneService sInstance;

私はそれを見つけるのに多くの時間を費やしているので、それが誰かを助けることを願っています！
