Hi people, After long try and there I got "finally" portaudio running on my cpu. I got the dumb error message "connection refused" rid of me, and FS seems to access the soundcard. I can choose the devices of my choice, and place a call. But when I place a call, I still get this: 2020-01-11 22:18:33.847800 [DEBUG] switch_core_state_machine.c:935 (sofia/external/123456) State REPORTING 2020-01-11 22:18:33.847800 [DEBUG] switch_core_state_machine.c:174 sofia/external/123456 Standard REPORTING, cause: INCOMPATIBLE_DESTINATION 2020-01-11 22:18:33.847800 [DEBUG] switch_core_state_machine.c:935 (sofia/external/123456) State REPORTING going to sleep 2020-01-11 22:18:33.847800 [DEBUG] switch_core_state_machine.c:610 (sofia/external/123456) State Change CS_REPORTING -> CS_DESTROY 2020-01-11 22:18:33.847800 [DEBUG] switch_core_session.c:1715 Session 17 (sofia/external/123456) Locked, Waiting on external entities 2020-01-11 22:18:33.847800 [DEBUG] switch_ivr_originate.c:3941 Originate Resulted in Error Cause: 88 [INCOMPATIBLE_DESTINATION] 2020-01-11 22:18:33.847800 [NOTICE] switch_core_session.c:1733 Session 17 (sofia/external/123456) Ended 2020-01-11 22:18:33.847800 [NOTICE] switch_core_session.c:1737 Close Channel sofia/external/123456 [CS_DESTROY] 2020-01-11 22:18:33.847800 [DEBUG] switch_channel.c:2047 (portaudio/1123456) Callstate Change RING_WAIT -> ACTIVE 2020-01-11 22:18:33.847800 [INFO] mod_dptools.c:3518 Originate Failed.
