App Modernization to Enable In-App VoIP Telephony

Summary

A VoIP service provider needed its existing iPhone app — which could only communicate via loopback VoIP — redesigned to enable VoIP dialing and call handling directly in the app. INNERLUXES's iOS developers rebuilt the app using the open-source PJSIP library, delivering full support for incoming and outgoing VoIP calls on time and within budget.
