Hello Nanang , I just tried compiling aps-direct branch and it went well after setting up passthroughcodec macros and the other APS releated stuff . I am able to run the symbian_ua app , able to make calls , but it crashes with Kern exec error - 3 . I noticed that the app is able to use g729 codec from the server logs . Any advise ?
