N-SIP  created  a  cross-plat form  VoIP  library.  Putting  aside UI  and  dependencies  the  library  is  less  than  50  KB! Our library was designed from day one to run on mobile platforms with wireless connectivity and it is not a customization of a PC library. It can be easily embedded as a Click-to-Call browser plugin, in applications, as On SIM VoIP app, in car infotainment  system,  hard-phones  and  STB’s.  The  library  is  very  efficient  in  terms  of  battery  and  memory consumption: While in conversation N-SIP's test app consumes about 70% battery compared to Sykpe and other VoIP
app.
