Recently my team developed an app used for phone call recording. After submitting to App Store review, the review team rejected it and clarified that I need to provide a demo account accessing to all features and functionality in the app. But here's the trouble, of which my app needs to sign in with the phone number of the SIM Card on the iPhone and use the number to make a call out through the Phone App. So seems that there's no way to provide a demo account for the review team to do that. So how should I do next?
