Hey guys
Here is what I typically do in a scenario like this:
SIPp instance no 1 (port x): handles registrations but will register with NOT with port X but with port Y. SIPp instance no 2 (port y): handles the "other" traffic, such as INVITE, MESSAGE whatever.
The reason for this is that when I do load testing, I cannot go off and kill my REGISTER SIPp instance plus I don't want to have to deal with timing issues etc (I haven't noticed that though). Of course, this assumes there is no NAT between you and the server, which in our test lab, we dont have (unless we are explicitly testing NAT scenarios).
Anyway, just another idea.

- I tried to REGISTER the SIPP endpoint in a single xml scenario file
with kamailio. This works as per usual. I then killed the SIPP instance and ran a new SIPP script listening on the same port before trying to send the INVITE to it. I expected this to work as the SIPP scenarios (both sending REGISTER and expecting INVITE) listened on the same port. However, the INVITE was not received by the SIPP endpoint. Can anyone think of a reason for this?
That should work - if you use UDP and the time interval between REGISTER and INVITE is small (<30 seconds to avoid NAT/FW issues).
Of course, it also depends if sipp is behind NAT/FW and the Contact used by sipp during REGISTER is correct. If there is some kind of NAT/FW then you should use fix_nated_register() before save().
