    A mobile app for placing telephone calls over an IP network. The app allows making calls only after playing appropriate add transmitted from the server. 

  •  

    The client required an easy tool for making phone calls via IP telephony technology integrated with commercial voice advertisement channel. 

  •  

    We have implemented the solution combining mobile platform with open source VoIP solution- Linphone, compatible with the SIP protocol. We have also subscribed a VoIP to PSTN (=classic telephony) account to a telecom provider to address users with "classic" phone line. We addressed number of features including video calls, conference calls, different address books integration, reviewing call history and text messaging.
