The **rtjson** module is updating the "from" sip header twice with the "from" and "to" json fields. By the way "to" sip header keeps unchanged. This is the json example: `.... response.routes[0].headers = { "from": { "display": "Anonymous", "uri": "sip:anonymous@anonymous.invalid" }, "to": { "display": "44444444", "uri": "sip:44444444@172.16.213.38" }, }; .... ` The result would be: From: Anonymous4444444444<sip:anonymous@anonymous.invalidsip:4444444444@172.16.213.38>;tag=1. To: sut <sip:0115555555@172.16.213.38:5060>. I modified one line and now works correctly `diff --git a/modules/rtjson/rtjson_routing.c b/modules/rtjson/rtjson_routing.c index 5542e63..60bdcad 100644 --- a/modules/rtjson/rtjson_routing.c +++ b/modules/rtjson/rtjson_routing.c @@ -481,7 +481,7 @@ int rtjson_prepare_branch(sip_msg_t *msg, srjson_doc_t *jdoc, srjson_t *nj) xuri.len = strlen(xuri.s); } if(xdsp.len>0 || xuri.len>0) { **- uacb.replace_from(msg, &xdsp, &xuri); + uacb.replace_to(msg, &xdsp, &xuri);** } } }` From: Anonymous <sip:anonymous@anonymous.invalid>;tag=1.
