[OpenSIPS-Users] YNT: Re: RFC3261 transaction matching failed error for the second 401 Unauthorized - Challenging the UE

Thu Oct 9 09:00:40 CEST 2014

Hi Bogdan, 

Thanks for your response. 
In this situation how can I configure opensips to pass this message to the destination. Is it a configuration change or should I use another function instead of t_relay ?

Kind regards

</div>Hi Kaan,

The log you refer to is a DBG and not an ERR (error) - when a new request is received, opensips (inside the t_relay) tries to match it against existing transactions to see if it a retransmission on not. The fact your request does not match means it is not a retransmission, but rather a new request.

Hi all,

I am making registration to the Open IMS nodes(192.168.2.3 and 192.168.2.5) simultaneously from IMS bench(192.168.2.11). Registration messages are going through OpenSIPS load balancer(192.168.2.141).

Registration messages which are going to first Open IMS node(192.168.2.5) completed succesfully.

But registration to second IMS node(192.168.2.3) is not completed successfully  since t_relay() function in OpenSIPS load balancer is giving "DBG:tm:matching_3261: RFC3261 transaction matching failed" error and not passing the           "Status: 401 Unauthorized - Challenging the UE    (0 bindings)" messages to IMS bench.

Below please find wireshark log and opensips logs in debug level=6.

Do you have any idea for this problem.

BR,
Kaan
