N-SIP created a cross-platform 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 massive multi-players online games.Our library answers the technological progress that made traditional telephony a dying technology. As IP traffic is already very reliable and available everywhere; bandwidth is constantly growing and above all – VoIP is much cheaper – cellular telephony will become a second choice. The only setback that may discourage a software designer from using VoIP is the need for VoIP servers. Hence, we can supply a dedicated server(s) with complete set-up.
