I just set up a new FreeSWITCH system on my home network, and set a forward for port 5080 to connect to Flowroute. While I'm debugging some call routing stuff, my logs are getting overrun with stuff like this: 2021-03-16 15:52:02.267501 [NOTICE] switch_channel.c:1118 New Channel sofia/external/7750@<my IP> [2de89b87-cd07-4c0f-b9fb-3da8e5a68d37] 2021-03-16 15:52:02.267501 [DEBUG] switch_core_state_machine.c:585 (sofia/external/7750@<my IP>) Running State Change CS_NEW (Cur 1 Tot 7822) 2021-03-16 15:52:02.267501 [DEBUG] sofia.c:10280 sofia/external/7750@<my IP> receiving invite from 80.94.93.12:62635 version: 1.10.5 -release-17-25569c1631 64bit 2021-03-16 15:52:02.267501 [DEBUG] sofia.c:7326 Channel sofia/external/7750@<my IP> entering state [received][100] 2021-03-16 15:52:02.267501 [DEBUG] sofia.c:7336 Remote SDP: v=0 o=- 81921704 81921704 IN IP4 0.0.0.0 s=pplsip c=IN IP4 0.0.0.0 t=0 0 m=audio 7628 RTP/AVP 100 6 0 8 3 18 5 101 a=rtpmap:100 speex/16000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-11 a=alt:1 1 : DF50DC48 0000001F 0.0.0.0 7628 2021-03-16 15:52:02.267501 [DEBUG] sofia.c:7739 (sofia/external/7750@<my IP>) State Change CS_NEW -> CS_INIT 2021-03-16 15:52:02.267501 [DEBUG] switch_core_state_machine.c:604 (sofia/external/7750@<my IP>) State NEW 2021-03-16 15:52:02.267501 [DEBUG] switch_core_state_machine.c:585 (sofia/external/7750@<my IP>) Running State Change CS_INIT (Cur 1 Tot 7822) 2021-03-16 15:52:02.267501 [DEBUG] switch_core_state_machine.c:628 (sofia/external/7750@<my IP>) State INIT 2021-03-16 15:52:02.267501 [DEBUG] mod_sofia.c:93 sofia/external/7750@<my IP> SOFIA INIT 2021-03-16 15:52:02.267501 [DEBUG] switch_core_state_machine.c:40 sofia/external/7750@<my IP> Standard INIT 2021-03-16 15:52:02.267501 [DEBUG] switch_core_state_machine.c:48 (sofia/external/7750@<my IP>) State Change CS_INIT -> CS_ROUTING 2021-03-16 15:52:02.267501 [DEBUG] switch_core_state_machine.c:628 (sofia/external/7750@<my IP>) State INIT going to sleep 2021-03-16 15:52:02.267501 [DEBUG] switch_core_state_machine.c:585 (sofia/external/7750@<my IP>) Running State Change CS_ROUTING (Cur 1 Tot 7822) 2021-03-16 15:52:02.267501 [DEBUG] switch_channel.c:2332 (sofia/external/7750@<my IP>) Callstate Change DOWN -> RINGING 2021-03-16 15:52:02.267501 [DEBUG] switch_core_state_machine.c:644 (sofia/external/7750@<my IP>) State ROUTING 2021-03-16 15:52:02.267501 [DEBUG] mod_sofia.c:154 sofia/external/7750@<my IP> SOFIA ROUTING 2021-03-16 15:52:02.267501 [DEBUG] switch_core_state_machine.c:236 sofia/external/7750@<my IP> Standard ROUTING 2021-03-16 15:52:02.267501 [INFO] mod_dialplan_xml.c:637 Processing 7750 <7750>->900442037697855 in context public I thought fail2ban was designed for stuff like this, but I don't see any auth attempts here (I set "log-auth-failures" to "true").
