Dear everyone : Recently ,I am doing some work on making a softphone with relatively complete functions. But I don't want to use pjsip and pjmedia APIs directly. On the contrary, I want to use higher level APIs--pjsua APIs ,but with some changes to the pjsip and pjmedia. How can I know the principles of enclosing pjsis and pjmedia to pjsua APIs. Thanks ahead! -------------- next part -------------- An HTML attachment was scrubbed...
