Re: [SR-Users] How to handle a 301 redirect request from a client?

its not a good idea to make manipulations in failure_route like you do. in failure_route you are working on the initial request. since you want to apply manipulation on the new user received from 300 response you need to use branch_route for this. thats one of his purpose. ________________________________ De : Benoît Panizzon &lt;benoit.panizzon(a)imp.ch&gt; Envoyé : vendredi 24 juin 2022 15:06 À : Patrick Karton &lt;patrickarton(a)hotmail.com&gt; Cc : Kamailio (SER) - Users Mailing List &lt;sr-users(a)lists.kamailio.org&gt; Objet : Re: [SR-Users] How to handle a 301 redirect request from a client? Salut Patrick Thank you for your help. I ended up with this: if (t_check_status("(301)|(302)") or (t_branch_timeout() and !t_branch_replied())) { $avp(destination) = $(T_rpl($ct){tobody.user}); xlog("L_ERR", "$cfg(route): Got: $avp(rstatus) $avp(rtext) towards $T_rpl($ct) => $avp(destination)"); append_hf("IMP-cust-profile-code: $var(cust_profile_code)\r\n"); $var(newai) = "<sip:" + $rU + "@" + $(ai{uri.host}) + ">"; append_hf("P-Asserted-Identity: $var(newai)\r\n"); $var(newdi) = "<sip:" + $rU + "@" + $(fu{uri.host}) + ">;reason=unknown"; append_hf("IMP-screening: no\r\n" ); append_hf("Diversion: $var(newdi)\r\n"); route(IMP_TRANSLATE_INBOUND); route(IMP_ROUTE_TO_CORE); exit; } It sort of starts working, but I'm not there yet :-) The next issue I am right now bumping into is that I translated some 'write is append' header towards the CPE ($tU and $fU) and now I am translating them again (as if they were sent from the CPE) and writing to them again so I end up with the original destination and new destination concatenated. Is there a way to 'reset' the $tU and $fU after setting them once, so that they can be set again? -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________
