In-app purchase required to allow users calling each other?

Hello.


We want to make an app allowing people to share details about items they possess and enabling them to call / message each other. We want to allow everyone to post free of charge but a user should pay a small fee to be able to message / call any other user - first time only - (both message and calls would go through our server / telephony center).


We are not sure whether we should use ip-app purchases for that or we can use other means of payment as well.


Thank you for taking the time to answer.
