With the Telecom framework, you get call and notification\nmanagement, foreground support and more. The new Jetpack library adds support\nfor:\n\n- Call streaming and transfer\n- Android Auto and Wear OS integration\n- Backward compatibility\n\nTo learn more about how to build a calling app with the Telecom library, check\nout the [Telecom](/guide/topics/connectivity/telecom/voip-app/telecom) guide.\n\nSupported telecom devices\n-------------------------\n\nStarting with Android 7 (API level 21), most phones support the Telecom\nframework, and they must do so for SIM-based phone calls to work. For devices\nlike tablets, which don't traditionally require a Telephony implementation,\nAndroid 14 (API level 34) introduces new requirements that mandate a proper\nTelecom framework implementation for tablets that support VoIP.\n\nUse `PackageManager` to see if the device supports Telecom: \n\n packagemanager.hasSystemFeature(PackageManager.FEATURE_TELECOM)\n\n| **Note:** Non-Telecom based devices don't support other platforms such as Wear OS."]]
