Hey Raphael,
I am also running into a similar problem. I tried analyzing the code to figure out what might be causing this. I am including my findings here in the hope that more experienced SIPp folks can verify this behavior and determine a fix or a workaround:
1. On startup, SIPp tries to determine the mode it is running in - MODE_CLIENT, MODE_SERVER, MODE_3PCC_A_PASSIVE, MODE_3PCC_CONTROLLER_A. (scenario.cpp)
2. ONLY if the first message in the scenario is of type "receive", the mode is set to "MODE_SERVER"
3. When a messages is received, based on the mode, it tries to take the appropriate action.
Now, in the scenario you described, I see that the mode is being detected as - not SERVER and not 3PCC*. In this case, it assumes that this message is not related to any known call. I'm still trying to debug why this happens. Note: I have verified that ALL the CALL-IDs in this scenario are the same - for register, invite as well as the responses such as 100, 180 and 200 - so that cannot be the problem.
I just thought I'd post this information in case someone already knew the answer and it would thus save me some debugging time. :-) Thanks in advance.

Hello,
I'm trying to build a scenario where sipp first registers a number and
then, wait for an INVITE. The problem is that after the registration,
the INVITE packets are discarded. If I split the scenario in 2
scenarios: 1 for the registration and 1 for answering the INVITE and
run one after the other, it works fine! Any help is welcome.
Thanks in advance.
Best Regards,
Raphael
This is the error I get:
