Hello,

it is default configuration works on TCP connection. Kamailio version is master ,also problem is tested on other versions. I tried to make call with sip-client and gives same error. in my search , EAGAIN error is about NIO connection problem in C that there isnt any room to write or any resource.

I will install another kamailio-node to test it .

Thanks

Yasin CANER

No idea, what might be wrong with you conf. But you might start by making a packetdump (of all traffic except eg ssh on all interfaces) to see if the problem is related to kamailio or some network related config on the machine.

Hello

Both of them , IPv4 and IPv6 tcp connection relaying cause error.

I compared master and 5.2 on github. There is a few changes on tcp_main.c file.

Regards.

Hello,

not clear from your messages so far, is relaying from TCP/IPVv4 to TCP/IPv6 not working with master, or all TCP sending fails no matter if IPv4 or IPv6 in both sides?

Cheers, Daniel

I found the problem. it is about Kamailio-master. When i test on 5.2 version, it can relay tcp sip request to other side. I think it is a bug for tcp connection.

Thanks.

Hi Yasin,

did I understood you correctly, you think there is a bug in kamailio git master related to TCP handling? Would be great if then you could open an issue with more details about it.

Best regards,

Henning
