[OpenSIPS-Users] How to recover from tcp_blocking_connect failed ?

[Rodrigo Pimenta Carvalho]

Dear OpenSIPS users,


According to the OpenSIPS log, a callee answered a caller with SIP OK.

Such SIP OK has the following contact:


                  Contact: "Group" <sip:g1r2u3p4o5 at 127.0.0.1:40348;transport=TLS;ob>;+sip.ice


However, it seems that there is no available connection to port 40348. That is, opensips cann't send any message to that port.

So, after opensips relaying a SIP ACK to g1r2u3p4o5, it caused the following error:


Jan 09 17:48:54 colibri-imx6 opensips[23115]: Jan  9 17:48:54 [23135] INFO:core:probe_max_sock_buff: using snd buffer of 320 kb

What is happening here?

How can a peer lost its connection or lost connect to opensips?

How to avoid this issue or recover from it?


I have no idea on what to do. Any hint will be very helpful!


Thanks a lot.
