Re: [SR-Users] TOPOS + RE-INVITE problem - Contact IP not updated

Hello, try to apply this setting for topos module. modparam("topos", "contact_mode", 0) 10.10.70.70 does not put the full contact uri in the R-INVITE. try put contact_mode to 0 (and not 1 or 2). ________________________________ De : sr-users &lt;sr-users-bounces(a)lists.kamailio.org&gt; de la part de c c &lt;c(a)netcontrol.fr&gt; Envoyé : lundi 23 mai 2022 08:38 À : sr-users(a)lists.kamailio.org &lt;sr-users(a)lists.kamailio.org&gt; Objet : [SR-Users] TOPOS + RE-INVITE problem - Contact IP not updated It seems that TOPOS is not working properly on RE-INVITE and stop masking IP and contact on some RE-INVITE. When a RE-INVITE is send with Kamailio IP as Request-URI TOPOS is not operating. Note : we are using the HTABLE trick to rewrite $ru and match the call but we would need to have TOPOS re-evaluating the dialog once done. We use a standard configuration with 2 modifications. 1. in route[DISPATCH] to set the HTABLE if(is_method("INVITE")) { $sht(ct=>$ci::$ft) = $sel(contact.uri); } 1. in route[WITHINDLG] to find the call if R-URI = myself if(has_totag() && uri==myself) { if($sht(ct=>$ci::$ft) != $null && $T_reply_code > 400) $shtex(ct=>$ci::$ft) = 10 ; if($sht(ct=>$ci::$tt) != $null) { $ru = $sht(ct=>$ci::$tt); if (is_method("BYE")) $shtex(ct=>$ci::$tt) = 10 ; route(RELAY); } } As you can see in the PCAP the RE-INVITE goes directly to calling stating with the Contact not updated and the 200 OK is also sent to called party with wrong Contact info too. <https://github.com/kamailio/kamailio/files/8730489/topos-issue.zip> This behavior breaks the BYE procedure. Any advice ? Chris
