I have developed an app which does app to phone calling using Sinch framework. Calling works fine but the issue is I see a 4 digit number on receiver's phone but I would like receiver to see the registered number of caller. So I would like to set caller id or something like that for this. I tried to google it but I was not able to find any solution for that. Since app to app calling is having api to set caller id but I'm looking for a solution to set caller id for Sinch app to phone calling.
would be nice to get some solution.
Else please suggest any other framework which does that.
You need to use our verification product to enable this and we need to certify you to set caller id. Mail us at [email protected] to start that process.
