 Posted: Thu Dec 16, 2021 9:16 am Post subject: [Freeswitch-users] Problem with socket connection |
 |
|
Hi, I am using FreeSWITCH (version 1.10.2-release-14-f7bdd3845a ~ 64bit), the system handles 30-70 simultaneous calls. On the other hand, we have an IVR system that uses the node-esl library to connect to FreeSWITCH.
The problem we have is that some calls are dropped at different stages of the IVR menu, and in the FS log we see the following.
In this case, a connection with the IVR was not established:
2021-12-15 13:31:43.332652 [DEBUG] sofia.c:7301 Channel sofia/external/XXXXXXXXXX@sip.telnyx.com (XXXXXXXXXX@sip.telnyx.com) entering state [early][183]
2021-12-15 13:31:43.332652 [DEBUG] switch_core_media_bug.c:970 Attaching BUG to sofia/external/XXXXXXXXXX@sip.telnyx.com (XXXXXXXXXX@sip.telnyx.com)

2021-12-15 13:31:43.332652 [ERR] mod_event_socket.c:488 Socket Error!
2021-12-15 13:31:43.332652 [NOTICE] switch_core_state_machine.c:386 sofia/external/XXXXXXXXXX@sip.telnyx.com (XXXXXXXXXX@sip.telnyx.com) has executed the last dialplan instruction, hanging up.

In this other example I don't see an error with the socket in the log, but the call cuts out just after reproducing this silence:
2021-12-14 21:20:08.732663 [DEBUG] switch_ivr_play_say.c:1933 done playing file silence_stream://250
2021-12-14 21:20:08.732663 [NOTICE] switch_core_state_machine.c:386 sofia/external/XXXXXXXXXX@sip.telnyx.com (XXXXXXXXXX@sip.telnyx.com) has executed the last dialplan instruction, hanging up.

Other example:
2021-12-15 13:08:10.452655 [DEBUG] switch_ivr.c:632 sofia/external/XXXXXXXXXX@sip.telnyx.com (XXXXXXXXXX@sip.telnyx.com) Command Execute [depth=1] play_and_get_digits(0 1 1 0 1234567890 phrase:greeting silence_stream://250 dialed_digits)

2021-12-15 13:08:30.092667 [NOTICE] switch_core_state_machine.c:386 sofia/external/XXXXXXXXXX@sip.telnyx.com (XXXXXXXXXX@sip.telnyx.com) has executed the last dialplan instruction, hanging up.

My impression is that the problem is related to the socket connection between the IVR and FreeSWITCH. The two things are installed on the same server (Linux Debian 10), any idea what could cause this problem? |

I would use tshark or tcpdump to perform a packet capture on the machine for
connection requests to port 8085 and see what's happening at that level.
Can you do any logging / debugging on the listener side to see whether the
request to connecto to port 8085 is being seen and handled in some way?
Antony.

It looks like you have outbound ESL so you have FS connecting to the IVR, not the other way around.IVR not running ? "mod_event_socket.c:484 Socket Error: Connection refused"
