Development of service

The basis is Teligent RCS Communicator

Specialists of Teligent company developed multifunction service based on the solution Teligent RCS Communicator. Project implementation was carried out in several steps. Within the first stage all functional parts of service were developed: SMS/MMS, convergence of VoIP and GSM (SIP2SIP, SIP-IN, SIP-OUT), video call (SIP2SIP), online and offline tariffing.

At the second stage work on integration of the convergent solution Teligent RCS Communicator with architecture elements into networks of the operator was carried out.

The next stage included development of cross-platform clients for OS Windows, Linux and Mac OS, the mobile client for the smartphones working based on Symbian S60 and Android. Later the client was developed for iOS and the WEB COMMUNICATOR.

Development of various clients gives the chance to users of Multifon to provide access to service by method, convenient for them, via the personal computer or phone. At the same time, thanks to observance of standards and specifications, a server part is capable to work practically with any third-party SIP client.
