What is com.android.server.telecom
Com.android.server.telecom is also known as the Android Telecom server. This app is responsible for managing any kind of call that you make on your Android device including SIM, VoIP, SIP, etc.
The Android Telecome server initiates and manages the calls on an Android device. Com.android.server.telecom is used for VoIP and SIM-based audio and video calls. It allows users to manage calls from the Android GUI which is Android Incallui.
When you place a call, the com.android.server.telecom uses the Android framework to initiate calls with the help of the SIM card module to establish the connection.
What is the Work of com.android.server.telecom?
To understand that, you need to understand the Android Telecom Framework. It has two package names: com.android.telecom and com.android.server.telecom.
com.android.server.telecom is stored in Kernal Space where the main kernel extensions and device drivers are stored.
The Android Telecom Framework contains three important elements:
- Telephony API which includes the Dialer app.
- The Phone Modem.
Basically, com.android.server.telecom acts as a communication medium between the Dialer app and the Phone Modem.
What Happens When You Make a Call?
When you go to the dialer app on your Android smartphone and dial a call, the information is sent to the Telecom Framework where com.android.server.telecom receives the information. It then initiates a system process called setDialing. This process is what informs the framework to connect to the phone modem and dial the call.
In a similar manner, when you hang up a call, com.android.server.telecom initiates a system process called setDisconnected. It instructs the Telecom framework to disconnect the call from the phone modem.
