more or less, but you make it sound complicated :p

Basically once the phone-to-phone is initiated you no longer need a
network connection as the webservice would take over to call both
parties. To initiate the phone to phone with the API is like hitting a
single URL, so it should be quick and easy to do if you have any kind
of window while connected to an access point.

Some providers allow you to end the call on the server side, however,
that is not documented as an option with the CallWithUs API.
