Hi, I already used pjsip 2.2 (to incorporate #1705 fix), but the echo was still very noticeable. When switching a voice call to speakerphone I can hear my echo clearly. Is it because I use am-nb codec and #1705 fix does not work well or for other reason ? And I saw there is a pjsip-iphone-audio-driver also for echo cancellation purpose. Has anyone had any experience with that ? Can it work with latest pjsip code ? Thanks Qiulang
