Hello,
the problem is the UAC initiating the call -- the ACK must have in the
request URI the SIP address from Contact header of the 200ok, but the
ACK has the address pointing to Kamailio.
Moreover, to get the ACK and the rest of the requests part of the dialog
through Kamailio, you have to do record routing in kamailio ( see rr
module - e.g., record_route() and loose_route() functions as per default
config file use).
You need to adjust your sipp scenarios.
Cheers,
Daniel
