Every Android Phone comes with pre-installed apps including com.android.server.telecom, and com.android.settings which are usually set to run in the background. If you want to stop them, so they don’t use any resources – there’s a way to do that on your device.

This article will show you what is com.android.server.telecom, how to disable it, and why it may be important for the health of your phone.

What is com.android.server.telecom?

The com.android.server.telecom app is a system process that manages phone calls and multimedia sessions in Android. It’s responsible for routing, call setup, and maintaining a connection between devices.

The app also provides user interface components and supports calling features like conference calls and caller ID blocking. 

You can’t disable the com android server telecom app because it’s a system process, but you can force stop it through your device’s Settings menu. Doing so will temporarily disable all calling features on your device until the app is restarted.

What is com.android.server.telecom used for?

As we discussed before the com.android.server.telecom is used for various things, including managing phone calls and voicemails, handling connections to wireless networks, and providing support for features like visual voicemail and call forwarding.

It’s an integral part of the Android operating system, and its code is constantly being updated by Google to improve the overall user experience. Here is a list of some reasons why the app is running on Android phones:


Com.android.server.telecom is used to manage phone calls on an Android device. It gives the facility to make outgoing and outbound calls, add new contacts and log call history.

As we mentioned above this system service is responsible for routing incoming and outgoing calls, managing conference calls, and handling call notifications. Also, it provides various call management settings, such as enabling or disabling call waiting, showing caller ID information, and choosing which ringtone to use for incoming calls.


When you make a phone call, your phone shares some information with the person, you’re calling. This is called “Call Details.” Here’s what you need to know about the class:

  • Your phone number is shared with the user you’re reaching.
  • The time of the call is shared with the person you’re calling.
  • The call duration is shared with the user you’re reaching.
  • Your location is shared with the person you’re calling.
  • Your device information is shared with the person you’re calling.


A Call.Callback is a function that lets InCallService and com android server telecom know that the current call has changed. This can include changes in the Call’s state, Connection, and phone numbers associated with the Call. Then, it can use this information to update the UI accordingly.


The Call.RttCall class contains the state of the RTT channel, which is stored with all the data needed to connect and communicate with the remote party.

This class allows you to manage the sending and receiving of RTT messages on an active call, as well as query the status of the channel.


CallAudioState is an object that contains information about the audio state of a call. It has the following properties:

  • IsMuted: A Boolean value indicates whether the Call is muted.
  • IsOnHold: A Boolean value that indicates whether the Call is on hold.
  • IsSpeakerphoneOn: A Boolean value that indicates whether the speakerphone is on.

The CallAudioState object also has the following methods:

  • ToggleMute(): Toggles the mute state of the Call.
  • ToggleHold(): Toggles the hold state of the Call.
  • ToggleSpeakerphone(): Toggles the speakerphone state of the Call.


The CallRedirectionService can interact with the com.android.server.telecom app to make an outgoing call, with the option of redirecting or canceling the Call.

This service is useful when you need to contact a Telecom customer but do not have their direct contact information. By using the CallRedirectionService, you can request that the Call be redirected to another number or canceled entirely.


A conference is a phone call in which more than one party participates. Conference calls can be conducted over the telephone or over the internet using a service like Skype.

In a conference call, all participants can usually hear each other. Often, a designated leader moderates the Call and can mute individual participants if necessary. Also, it can be used for business meetings, team updates, or even to catch up with friends and family.


A connection is a normal or video call with a remote endpoint. You can use it to carry voice and/or video traffic. The term “endpoint” refers to any device that can receive or place a call, such as a telephone, computer, IP phone, etc. A connection typically uses the public switched telephone network (PSTN) to connect two endpoints.


The Connection.RttModifyStatus class provides constants for the responses generated by session modify requests sent via Call#sendRttRequest(). These constants can be used to determine whether a session modification request was successful and, if not, what the error was.

Successful session modification requests will have a status of Connection.RttModifyStatus.SUCCESS. If a session modify request fails, the status will be one of the following:

  • Connection.RttModifyStatus.FAILED: The session modify request failed for an unknown reason.
  • Connection.RttModifyStatus.REJECTED: The remote party rejected the session modification request.
  • Connection.RttModifyStatus.TIMEOUT: The session modification request timed out without a response from the remote party.


With the Connection.RttTextStream class, you get a way to control your video sessions for a connection. This can be used to, for example, change the size or position of the video window, or add text to the video stream.

For example, if the far-end party does not support video, or if the connection is slow and video quality is poor, it may be desirable to disable the video session. The following methods are provided for controlling the video session:

  • DisableVideo() – This method disables the video session. Once disabled, the video window will be closed, and no further attempt will be made to establish a video session.
  • EnableVideo() – This method enables the video session. If a video session exists, one will be established.
  • IsVideoEnabled() – This method returns true if the video session is enabled and false otherwise.


Connection requests are used to establish communication between two devices or components, such as when establishing a new network connection. They can also be used to request other types of connections, such as when making a new database connection.

When making a connection request, it is important to include all necessary information so that the entity can properly process the request. This could result in the request being denied or delayed.


InCallService is created to work with com.android.server.telecom which allows applications to manage phone calls. It provides the ability to respond to calls. In addition, it offers the ability to control the call experience, including setting up conference calls and managing call waiting.


InCallService.VideoCall can be used to issue commands to the Connection.VideoProvider associated with a Call. The following methods are available:

  • SendSessionModifyRequest(VideoProfile fromProfile, toProfile) – Sends a request to upgrade or downgrade the current Call’s quality.
  • CallSessionModifyRequest(VideoProfile fromProfile, toProfile, String extras) – Sends a request to modify the video quality for the current Call.
  • RequestCameraCapabilities() – Requests information about the camera capabilities of the remote device.
  • SetParameters() – Sets various parameters for the call session (e.g., enable/disable HD video).


When you make a phone call, the PhoneAccount associated with your device will be used to send or receive the call. It contains metadata about the account, such as its type and features, and an identifier that uniquely identifies the account.

This is useful for distinguishing between different calling methods, such as VoIP, SIP, and PSTN. A PhoneAccount can also manage and monitor calls placed or received through a specific account.


A RemoteConference is a conference that can be provided by a ConnectionService to another. This allows for two or more Connection Services to connect with each other and share data, audio, and video.

The class was created to provide a connection between two or more individuals, or it can be used between two or more devices.


The TelecomManager class provides applications with access to information about active calls and the ability to manage these calls. This includes the ability to register and unregister phone numbers, as well as the ability to initiate and terminate calls.

This class is a service that maintains a list of all active calls and phone numbers. However, it’s responsible for routing outgoing calls to the correct destination.

The service is accessed through an instance of the TelecomManager class, which can be obtained by calling Context.getSystemService(Context.TELECOM_SERVICE).

 Applications can use the TelecomManager class to:

  1. Register and unregister phone numbers.
  2. Initiate and terminate calls.
  3. Check the status of active calls.
  4. Get information about registered phone numbers.
