Remote call from another phone I am in US now and I need to call Ukraine, it would be way too expensive as I need to make a lot of calls (business related).

I have a friend in Ukraine so I though if there was a way to connect my phone from US to his phone in Ukraine and make calls from his phone so it’s cheap.

The requirements are:


an app that could transmit the call audio, from my phone to his phone to the final destination phone, back and forth.
less expensive than cellular service between US and Ukraine (but willing to pay in setup time, service or for an app if it will work)


Is there some way to do that with both of us using iOS and iPhones?
You can set up a voice relay. Suggest you consider an Android phone. Apple would never approve such an app.
