Hi Bogdan,

Thank you for hint. I have enabled in Opensips. After enabling in SIPP too it worked.

Hi, Agalya,

Do you do Record Routing in OpenSIPS and SIPP ? This is a must.

Hi team,

We are trying to run load test on OpenSIPS for our project.
We are using sipp tool to generate load test. We are facing some issues when we try to run a successful call.

Source SIPp ----------Opensips --------------->Dest SIPp

There are two scenarios.

1.       (Works) Failure code, send Invite from source SIPp and receive 480 .

2.       (Fails) Answering call, Send Invite from source SIPp  and receive 200 OK.
In first case, after receiving 480, OpenSIPS could able to send ACK to the destination SIPp
Where as in second case, there are two issues

                                 i.            After receiving 200 OK, OpenSIPS doesn't send ACK to destination SIPp. When it tries to send ACK out, it fails stating, usd_send_failed. Or

                               ii.            Also the same ACK keeps looping somehow for huge number of times.

For the 2nd case, we are running only single call and it is failing.
Am attaching the log of SIPp messages and some snippet of OpenSIPS logs.

Have you come across this scenario? Why ACK is been looped so many times?
Also we see ACK message is so small, but it says, usd_send is failed due to message is long.
Any clue here would help us  a lot.

Regards,
Agalya
