VOIP Feature in IOS and Android Application

We have a mobile app ( IOS and Android ) and we need to implement a feature of VOIP Calling for customers . The workflow will be :

The User of the App will call a customer via VOIP server in UK to a phone number .

The app will call a API with date /time / details of the call for logging purposes. (success/fail)

The apps are developed in native code both for IOS and Android.

We need also recommendations for VOIP services / libs. If you implemented this in a previous app would be a great advantage.

The payment for the app will be done on delivery / after testing.

Thank you

Skills: Android, iPhone, Mobile App Development
