Q:

How to set caller id for Sinch App-To-Phone calling?

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.

A:

You need to use our verification product to enable this and we need to certify you to set caller id. Mail us at support@sinch.com to start that process.
