Hi, I have Freeswitch git head revision, configured with FreeTDM module and Sangoma ISDN library with A108 board. The problem I have is that there is one trunk (FreeTDM/9:) where all calls fail with a cause 111. Nothing changes if I restart Freeswitch or I do a wanrouter restart. All other trunks work fine. The freetdm.conf is: http://pastebin.com/XWbUBwhp The freetdm.conf.xml is: http://pastebin.com/XVJpPSL6 The wanpipe9.conf: http://pastebin.freeswitch.org/14589 Tracing the Q931 with wanpipemon what I see is only Q921 RR messages in the two directions, so the SETUP message is not sent to the other end! In the Freeswitch log I see: 2010-11-21 23:17:14.320500 [DEBUG] mod_freetdm.c:1334 Connect outbound channel FreeTDM/9:1/393494255737 2010-11-21 23:17:14.320500 [NOTICE] switch_channel.c:784 New Channel FreeTDM/9:1/393494255737 [cd6c2968-40ee-41c6-bbe5-d7c7c8222c40] 2010-11-21 23:17:14.320500 [DEBUG] mod_freetdm.c:1348 (FreeTDM/9:1/393494255737) State Change CS_NEW -> CS_INIT 2010-11-21 23:17:14.320500 [DEBUG] switch_core_session.c:1064 Send signal FreeTDM/9:1/393494255737 [BREAK] 2010-11-21 23:17:14.320500 [DEBUG] ftmod_sangoma_isdn.c:692 [s9c1][9:1] Changed state from DOWN to DIALING 2010-11-21 23:17:14.320500 [DEBUG] ftmod_sangoma_isdn.c:471 [s9c1][9:1] processing state change to DIALING 2010-11-21 23:17:14.320500 [INFO] ftmod_sangoma_isdn_stack_out.c:142 [s9c1][9:1] Outgoing call: Called No:[393494255737] Calling No:[0872868784] 2010-11-21 23:17:14.320500 [INFO] ftmod_sangoma_isdn_stack_out.c:149 [s9c1][9:1] Sending SETUP (suId:1 suInstId:24 spInstId:0 dchan:9 ces:0) 2010-11-21 23:17:14.321526 [INFO] ftmod_sangoma_isdn_stack_rcv.c:248 [s9c1][9:1] Received RELEASE/RELEASE COMPLETE (suId:1 suInstId:24 spInstId:2157) 2010-11-21 23:17:14.321526 [DEBUG] ftmod_sangoma_isdn_stack_hndl.c:511 [s9c1][9:1] Processing RELEASE/RELEASE COMPLETE (suId:1 suInstId:24 spInstId:2157) 2010-11-21 23:17:14.321526 [DEBUG] ftmod_sangoma_isdn_stack_hndl.c:552 [s9c1][9:1] cause:111 2010-11-21 23:17:14.321526 [DEBUG] ftmod_sangoma_isdn_stack_hndl.c:559 [s9c1][9:1] Changed state from DIALING to TERMINATING 2010-11-21 23:17:14.321526 [DEBUG] ftmod_sangoma_isdn.c:471 [s9c1][9:1] processing state change to TERMINATING 2010-11-21 23:17:14.321526 [DEBUG] ftdm_io.c:4838 [s9c1][9:1] Scheduling safety hangup timer 2010-11-21 23:17:14.321526 [DEBUG] mod_freetdm.c:2049 got clear channel sig [STOP] 2010-11-21 23:17:14.321526 [DEBUG] switch_channel.c:2455 (FreeTDM/9:1/393494255737) Callstate Change DOWN -> HANGUP 2010-11-21 23:17:14.321526 [NOTICE] mod_freetdm.c:2074 Hangup FreeTDM/9:1/393494255737 [CS_INIT] [PROTOCOL_ERROR] 2010-11-21 23:17:14.321526 [DEBUG] switch_ivr_originate.c:3439 Originate Resulted in Error Cause: 111 [PROTOCOL_ERROR] 2010-11-21 23:17:14.321526 [DEBUG] switch_core_state_machine.c:320 (FreeTDM/9:1/393494255737) Running State Change CS_HANGUP 2010-11-21 23:17:14.321526 [DEBUG] switch_channel.c:2471 Send signal FreeTDM/9:1/393494255737 [KILL] 2010-11-21 23:17:14.321526 [DEBUG] switch_core_session.c:1064 Send signal FreeTDM/9:1/393494255737 [BREAK] 2010-11-21 23:17:14.322566 [DEBUG] switch_core_state_machine.c:557 (FreeTDM/9:1/393494255737) State HANGUP 2010-11-21 23:17:14.322566 [DEBUG] mod_freetdm.c:515 [s9c1][9:1] Changed state from TERMINATING to HANGUP 2010-11-21 23:17:14.322566 [DEBUG] ftmod_sangoma_isdn.c:471 [s9c1][9:1] processing state change to HANGUP 2010-11-21 23:17:14.322566 [DEBUG] ftmod_sangoma_isdn.c:564 [s9c1][9:1] Acknowledging remote abort 2010-11-21 23:17:14.322566 [DEBUG] ftmod_sangoma_isdn.c:600 [s9c1][9:1] Changed state from HANGUP to HANGUP_COMPLETE 2010-11-21 23:17:14.322566 [DEBUG] ftmod_sangoma_isdn.c:471 [s9c1][9:1] processing state change to HANGUP_COMPLETE 2010-11-21 23:17:14.322566 [DEBUG] ftmod_sangoma_isdn.c:608 [s9c1][9:1] Changed state from HANGUP_COMPLETE to DOWN 2010-11-21 23:17:14.322566 [DEBUG] ftmod_sangoma_isdn.c:471 [s9c1][9:1] processing state change to DOWN 2010-11-21 23:17:14.322566 [DEBUG] ftmod_sangoma_isdn_support.c:46 [s9c1][9:1] Clearing call data (suId:1 suInstId:24 spInstId:0) 2010-11-21 23:17:14.322566 [DEBUG] ftdm_io.c:2385 channel done 9:1 What can I do do put trunk 9 in working state?
