I am developing an Android application for video calling using RTSP/TRMP and LibStreaming. When i initiate a call from my app, i cant able to understand thether the other end is ringing / attend my call.
I would like to know how to set a ringback tone for an outgoing call. I need to play it till the other user attend the call or reject the call
For video calling, you can use WebRTC. its good library
you can check demo
Using RTSP, it will difficulty for you. if you want one way live steaming then RTSP is fine

I am planning to create a video calling app for iOS in Swift. For the project I decided to select Agora.io as the chosen SDK. I wanted to know whether I can implement Picture-In-Picture mode ?
My use case is, If a user decided to chat with someone while he is on a video call with someone else or the same person he is currently on a video call. So that he can put the remote video preview in P-I-P mode and send and receive chat messages ?
I’m using Twilio Android API to perform a VoIP call between two Android clients. Is it possible to track the current volume of the call?
The need for such possibility comes from the following use case: I want to request audio focus only when another party is talking and abandon it as soon as the silence is detected on the line.
Twilio developer evangelist here.
As far as I can see in the Android Programmable Voice documentation, there is no access to the audio stream in order to track the volume of the call.
This is likely something you could achieve if you were making audio calls between apps using the Twilio Video SDK for Android. (And if you are only making app to app calls, then sound quality will be better too as it's not downsampled for the phone network.)
I have created a calling app for android using Sinch. However I would like give the user the ability to take part in the call via loudspeaker.
I went through the documentation for a bit and thought that Sinch could not help me this but this is actually and android thing.
So how can I redirect a call to the loudspeaker upon a button press?
Instance of sinch client has method to get audio controller. There you can find method for setting speaker enable/disable.
For my case:
mSinchClient.getAudioController().enableSpeaker();
It is possible to programmatically interact with a phone call? Can you, for example, play audio to a caller from a program?
Google has not exposed any API which allows us to feed data to a particular ongoing call. You can however have control over a call. Check this article : here
