The Android Telecom framework is a package that mainly helps you manage calls on any android device. For example, it can be SIM-based calls, VOIP calls, etc., that use the Telephony framework, SIP (e.g., the SipConnectionService), or a third-party VOIP ConnectionService. We can use it as a switchboard, routing calls, and audio focus between Connections of ConnectionService implementations. On the other side, the InCallService implementations can offer a user interface for calls. The is primarily used for incall service. Its main function is to control and organize calls and log calls. It go hand in hand with Android Telecom Server.

Here, we have given a few calling use cases along with increasing levels of complexity.

Implementing the self-managed ConnectionService API:

It is perfect for those who are developers of standalone calling apps. These apps don’t showcase their calls within the default phone app. Besides, these apps also don’t want to show other calls in their user interface. When you use a self-managed ConnectionService implementation within your standalone calling app, it makes you sure that the app will interoperate both native telephony calling and standalone calling apps implementing the API. This one can manage audio routing.

Implement the managed ConnectionService API:

It offers the development of a calling solution and offers a user interface for calls. The solution depends on the existing device phone application (see getDefaultDialerPackage()). A third party implementation of SIP Calling or a VOIP calling service is a few instances of it. The ConnectionService doesn’t have any connection with the associated user interface.

Implement the InCallService API:

It gives you a replacement of the default Phone/Dialer app of any device. In this case, you don’t get any calling facility. It features the user-interface side of calling. This API needs to handle all types of Calls instead of assuming the nature of the calls. SIM-based telephony call is an example of it. Besides, it doesn’t need to implement calling restrictions that depend on ConnectionService. For instance, it must not enforce any Telephony restrictions for making video calls.

Implement both the InCallService and ConnectionService API:

This one can be useful for making your ConnectionService. It depends on the calling solution and is a complete user interface. The API showcases all Android calls in that similar user interface. Thus, you can make sure that InCallService doesn’t assume the source of the calls. Along with this, you have to make sure that the ConnectionService implementation you have can work without the default phone app.

By following the procedure, you will be capable of implementing the telecom API when you don’t wish to utilize any system Phone App but want to get a replacement. The API also allows you to experience a calling solution that is associated with the Android calling experience. You can take the help of in-call service API to replace the default Phone App from your android device. Whether you want to make any relation with a third-party app with the support of means like VOIP, use the connection service API. You can integrate a calling solution, manage screen calls, redirect any call, etc., with the help of each component of Telecom. The vital thing is that it assists you in replacing the default Phone app.

Here, we have given many details like what it is, why it is so important, how to use and its functions of. Along with this, we have answered different questions related to this.
