Are there any non-GPL SIP libraries/SDKs that'll let me implement SIP for iOS?

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.

  • 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. – cloudnaut Oct 11 '13 at 19:44
  • Pretty old thread, but here is a link with [xcode project for osip/eXosip/c-ares](http://sip.antisip.com/xcode/xcode-exosip.tar.gz) - minor change to the project may be required over various osip/exosip versions! – AymericM Jan 05 '16 at 17:50
  • You have to [do a lot](http://roadfiresoftware.com/2013/08/the-problem-with-using-lgpl-v2-1-code-in-an-ios-app/) in order to use an LGPL library in iOS app. – Franklin Yu Apr 28 '17 at 18:20

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.
