Is there any SIP library to implement voice calls in IOS/B4I? Anybody knows?
Hi @Erel , THIS - http://www.linphone.org/technical-corner/liblinphone/overview - is a library for IOS and doesn't look to be complicated to wrap and develop for B4I... I already used LinPhone in an App for IPhone... What do you think? Is it possible to create a B4I library from that?
Commercial use is always a relative concept. For example, you can offer the app for free and earn money with the calls completion ... and open source is a relative concept also: your app could be open but using paid plugins for some features. By the way, like Android OS...It looks like a quite complicated library to wrap and it's license is GPL which means that you will need to make your app open source as well.
They offer a commercial license as well. The price is not listed.
