Hi, for the SIP signaling I think you should be able to accomplish this with implementing a pjsip module in which you modify the messages when they are received and sent. Have a look at pjsip_endpt_register_module(). For the RTP traffic you can implement your own media transport that uses one of the existing media transports as a slave transport and then do your own modifications on the RX/TX packets. Have a look at http://www.pjsip.org/docs/latest/pjmedia/docs/html/group__PJMEDIA__TRANSPORT.htm Good luck!
