[SR-Users] "append_rpid_hf()" and "append_hf()" issues

Hi everybody, I've been testing and setting up kamalio 3.0.3 with MySQL since a few weeks ago. All the basic functionalities are working properly, but now I have an issue which I'm not been able to solve by myself. I've read documentation and posts, but no idea about what is happening. This is the issue. I'm trying to append Remote Party ID field to the SIP message header. I've been trying with both "append_rpid_hf()" and "append_hf()" and I can't see any Remote Party Header at the SIP messages sniffed with wireshark. Here is the configuration I've tried: #para cargar los Remote party ID de la tabla suscriber modparam("auth_db", "load_credentials", "$avp(s:rpid)=rpid") modparam("auth", "rpid_avp", "$avp(s:rpid)") modparam("auth", "rpid_prefix", "<sip:") modparam("auth", "rpid_suffix", ";user=phone>;party=calling;screen=yes;id-type=subscriber;privacy=off") #Modificacion para no pedir autenticacion si viene desde un trusted if (!allow_trusted("$si", "$(proto{s.toupper})")) { if (!proxy_authorize("umh.es", "subscriber")) { proxy_challenge("", "0"); exit; } if (is_method("PUBLISH")) { if ($au!=$tU) { sl_send_reply("403","Forbidden auth ID"); exit; } } else { if ($au!=$fU) { sl_send_reply("403","Forbidden auth ID"); exit; } } append_rpid_hf("$fU", ";party=calling;id-type=subscriber;privacy=off;screen=yes"); consume_credentials(); ####### I also tested the following # append_hf("Remote-Party-ID: <sip:$avp(rpid)@$avp(domain);user=phone>;privacy=$avp(privacy);party=cal ling\r\n"); # append_hf("P-Asserted-Identity: <sip:$avp(rpid)@$avp(domain)>\r\n", "Call-ID"); # consume_credentials(); } } In a similar post I've read that the user had a problem because of the domain table. I have both the domain name and the IP of the host defined, and I also get response with "$avp(s:rpid) , when RPID field is defined to a subscriber. As I said I can't find the mistake, so any help would be appreciated. Thanks in advance and best regards, Ricardo Dominguez
