Hello, As discussed in my post here: http://blog.krisk.org/2013/09/learning-stupid-nat-tricks-from-apple.html My company is interested in sponsoring the development of Content-Encoding: deflate support in pjsip. The resulting work would be submitted for inclusion into pjsip (compatible with both licenses). Please reply to me directly if you are interested. Thanks! -- Kristian Kielhofner
