Hi Benny/Nanang I have experienced a peculiar problem that was not in previous release but in 1.1 APS Direct release..I am using symbian_ua_gui application with direct APS. I have modified the function like this int symbian_ua_answercall() { PJ_ASSERT_RETURN (g_call_id != PJSUA_INVALID_ID, PJ_EINVAL); ////////////////2nd call//////////// if (callCounter() == 2) { pjsua_call_set_hold(first_call_id, NULL); } ////////////////2nd call//////////// return pjsua_call_answer(g_call_id, 200, NULL, NULL); } It hold the first call and answer the second call. But the problem is for the second call X-Lite end can hear voice and no voice in pjsip end. Experiment was like this: 1. call from X-Lite to pjsip 2. call from another X-Lite to pjsip Can anyone please tell me the solution please... -- S. M.
