Hi all, Guys I know the question could be too vague, but I have a customer that just reported frequent failure to place outbound calls though a PSTN gateway on the LAN. I looked at the logs and I seem to be able to confirm that FS fails to place the call through the gateway and that the issue resides on the FS side since the first channel that s killed is tht of the internal extension registered to FS and then FS send the BYE to gw and kills the channel. What are possible causes of this? I know you always like to look at complete logs but here's a snip that could shed some light on the disconnection. (I can provide full logs if required and worthed) 2009-12-04 11:21:56 [DEBUG] sofia.c:3037 sofia_handle_sip_i_state() Channel sofia/internal/200@172.16.3.5 entering state [ready][200] 2009-12-04 11:21:59 [DEBUG] sofia.c:3037 sofia_handle_sip_i_state() Channel sofia/internal/200@172.16.3.5 entering state [terminated][200] 2009-12-04 11:21:59 [NOTICE] sofia.c:3597 sofia_handle_sip_i_state() Hangup sofia/internal/200@172.16.3.5 [CS_EXECUTE] [NORMAL_CLEARING] 2009-12-04 11:21:59 [DEBUG] switch_channel.c:1660 switch_channel_perform_hangup() Send signal sofia/internal/200@172.16.3.5[KILL] 2009-12-04 11:21:59 [DEBUG] switch_core_session.c:933 switch_core_session_signal_state_change() Send signal sofia/internal/ 200@172.16.3.5 [BREAK] 2009-12-04 11:22:00 [DEBUG] switch_ivr_bridge.c:371 audio_bridge_thread() sofia/internal/200@172.16.3.5 ending bridge by request from write function 2009-12-04 11:22:00 [DEBUG] switch_ivr_bridge.c:426 audio_bridge_thread() sofia/pstn/22909980@172.16.3.46 receive message [UNBRIDGE] Is the 6th line normal behavior for ending the channel?
