问题
I am developing an app with SINCH Platform for VOIP feature.
I am performing an app to app call.
I am aware that if Callback URL of application Server is set on SINCH Dashboard then it will not trigger DICE (Disconnect Call Event callback) [refer here] event for App to App Call.
But I have to manage all call details with my App Server. How Can I manage it from my Mobile App? (Like how can i notify my app server that last call was about of 50 seconds? So my server can manage relevant credit for that user as per call time)
I know that I can perform request to my app server with call details after every call end but what to do in below scenario?
1> App to App call is on Going (Caller 'A' and Recipient 'B')
2> Caller 'A' presses home button while app to app call is onGoing.
3> Now Caller 'A' removes application from recent task as well (By Swiping Left or Right from Recent Task Screen)
4> Now Caller 'A' Clears app data and gets register again with My App.
In This case how can I send request from Caller 'A' Device to My App Server.
I have found that Sinch perform rest Request as "sandbox.sinch.com/V1/Session". Is It of Any Use for me?
