Everything You Need to Know About com.android.server.telecom

Did you know that there is a whole dedicated system to manage the calling function on your Android device smoothly? com.android.server.telecom (used.com.android.server.telecom service) is the Android Telecom framework that governs the calling functionality on Android devices. Curious to know more about the framework, its importance, and how it works? Read the blog to the interesting answers.

What is com.android.server.telecom?

com.android.server.telecom is the Android service package that works as the interface required to make audio and video calls and other functions related to calling. It initiates, ends, and manages calls, including SIM-based calls using the Telephony framework, Voice over calls using SIP, or a third-party VOIP ConnectionService.

The com.android.server.telecom uses the Android framework to establish the connection after a call is initiated on an Android phone. It also displays the options we see on a dialer during a call.

The Android Telecom framework supports two essential components: ConnectionService and InCallService.

ConnectionService is mainly used for telephony ConnectionService to connect calls with mobile carrier networks.

InCallService works with com.android.incallui APK file to provide a User Interface to manage calls. For instance, the Dialer app provides different functions like Dial, Disconnect, Hold Call, etc. The most basic functions include Outgoing calls, Incoming calls, Hold calls, Resume calls, and Disconnect calls.

How does Android Telecom Framework Work?

The Android Telecom framework includes three important components:

  1. android.server.telecom
  2. Telephone API, which includes the dialer
  3. The phone Modem.

com.android.server.telecom acts as the bridge or middle tier between the dialer app and the phone modem. It receives the information from the dialer app and initiates processes. For instance, we make a call through the dialer app, com.android.server.telecom receives the information for the Telecom framework and initiates the setDialing system process. The setDialing process informs the Telecom framework to connect to the phone modem to dial the call.

Similarly, the com.android.server when we disconnect the call.telecom initiates the setDisconnected system process to instruct the Telecom framework to connect with the phone modem to disconnect the call.

Functions of com.android.server.telecom


The function is responsible for incoming and outgoing calls. It displays the name and other details on the screen during calls.


As the name itself explains, Call.details fetches the caller’s details from the android system database to display.


The Call.Recall function is responsible for creating the route for the Call or rerouting the path for the Call to facilitate users a smooth conversation.


Callaudiostate stores all the data related to a call. For instance, caller id, IP address, how long the Call was muted or on hold or the total time of call, and other details. In addition, it also stores call recording information from start to end.
