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!
