Hi Guys,

We are modifying "from" and "to" headers with rtjson module via a json struct. It works fine in INVITE, TRYING, RINGING and OK but not in the following messages. Kamailio It's changing ONLY "from" and "to" URI BUT NOT the DISPLAY NAME. I think it's the tm module but I can't figure out how to confirm this. Maybe I need to configure something else in my cfg or could it be a bug?

My json struct that is handled by rtjson module

      response.routing = "serial";
        //response.routing = "parallel";
        response.routes = [];
        response.routes[0] = {};
        response.routes[0].uri = "sip:1111111111@172.16.213.31:5060";
        response.routes[0].headers = { // Headers to be modified
                "from": {
                        "display": "1111111111",
                        "uri": "sip:111111111@172.16.213.38"
                },
                "to": { 
                        "display": "2222222222",
                        "uri": "sip:2222222222@172.16.213.38"
                },
        };
        response.routes[0].headers.extra = {};//"X-Hdr-A: abc\r\nX-Hdr-B: bcd\r\n";

This is part of my cfg

....
modparam("dialog","dlg_flag", FLD_START)
modparam("uac","restore_mode","auto")
modparam("uac", "restore_dlg", 1)
....

        # account only INVITEs
        if (is_method("INVITE") && !has_totag()) {
                setflag(FLT_ACC); # do accounting
                setflag(FLD_START); # do accounting
                setflag(FLT_ACCMISSED);
                setflag(FLT_ACCFAILED);
        }
