Mobile SIP Client
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 a “classic” phone line. We addressed a number of features including video calls, conference calls, different address book integration, reviewing call history and text messages.
