Hi, I further debug this issue and found an interesting problem. So if both sides use pjsip 2.2 then echo cancellation does not work. If both sides use pjsip 2.1 echo cancellation work well. And if one side use 2.1 and the other use 2.2 then echo cancellation only work on 2.2 side !! So any advice how I can fix the issue ?
