[SR-Users] Initial REGISTER request/response in 3rd Party Register

[jyaim]

Hello,

I'm using Kamailio with a SIP Application Server, when a user
registers on the IMS Core a 3rd Party REGISTER request is sent to the
application server to start some logic.
I'm trying to add in the 3rd party register request body the initial
REGISTER request sent by user device, and the 200 OK response sent
back by Kamailio.

Do you think it is possible to configure Kamailio to get this behaviour ?

Thank you!
