PJSIP version 1.7 has been released, with two major features added, namely official PJSIP support for iOS (iPhone/iPad/iPod touch devices) and support for multipart message bodies. The iOS port added native CoreAudio audio device implementation usable for both Mac OS X and iOS, and it also utilizes the device’s built-in echo cancellation feature for more robust echo cancellation. The port also added built-in iLBC codec that comes with the device.
This version also fixed many bugs, part of which discovered during the last SIPIT 26 in Sweden.
