I am trying to use audio call in app, But when I call from a device to other device, It does not connect with device and automatically disconnected with twilio Api. What is that problem occurred in app?

Are you using the Twilio Programmable Voice SDK in an iOS app here? What is the code you are using to place the call? And your TwiML App code? — philnash, Nov 21 '18 at 06:27
@phllnash Yes, I am using Twilio Programmable Voice SDK and Callkit. — Pankaj Jangid, Nov 21 '18 at 06:58
Ok, and what about the code. It's hard to tell what is wrong from a log snippet. — philnash, Nov 21 '18 at 13:15
@philnash I found issue, this is from our server side issue. Notification does not contain body statement, so that issue occurs. Thanks — Pankaj Jangid, Nov 23 '18 at 11:06
