App Modernization to Enable In-App VoIP Telephony

About Our Client

Glotes, a VoIP service provider.

Challenge

Glotes needed to redesign the existing iPhone app that was only able to communicate via loopback VoIP means. The Client was looking for skilled iOS developers who would enable VoIP dialing and call handling right from the app.

Solution

With over 10 years of delivering telecommunication software, ScienceSoft redesigned the existing iPhone app using the open-source library PJSIP, under the condition that the Client would offer its application for free.

The developed app fully supports incoming and outgoing VoIP calls and contains a single VoIP dial button and an incoming VoIP call view.

Results

Glotes received a complete solution that allowed users to make phone calls using VoIP telephony right from the app. The project was finished on time and within the budget.

Technologies

MacOS X 10.6, Xcode 3, iPhone SDK 3, UIKit, PJSIP library.
