Proprietary:

Open source: GPL/LGPL

• linphone
• exosip

Answer 2

oSIP is LGPL and therefore can be used (as a library) in commercial and closed-source projects. It compiles easily for arm. It is the SIP library used by linphone for iPhone; however, linphone is GPL.

Infinitive

Could you give an example how to compile it for arm? Where do I specify the architecture? I just compiled it on mac os x but of course an ios project can't use the lib. – Edelstein

Pretty old thread, but here is a link with xcode project for osip/eXosip/c-ares - minor change to the project may be required over various osip/exosip versions! – Alroi

You have to do a lot in order to use an LGPL library in iOS app. – Permit

Answer 3

These days SIP over WebRTC is getting popularity. It uses SIP Signaling and WebRTC as Media which is provided by google.

Following options are also very good if you to avoid getting into SIP level complexities.
