[OpenSIPS-Users] Problem with force_send_socket

[Bogdan-Andrei Iancu]

Hi Olle,

Are you sure the setup is correct ? based on the error log

2018-03-22T16:58:50.517287+00:00 err sipedge-qa-1 ERROR:tm:msg_send: 
send() to 172.27.251.4:5070 for proto tcp/2 failed

you are trying to send to 172.27.251.4:5070 as destination. In the same 
time, you use the same IP and port as local socket (as source).


Best regards,
