Hello, Others might be able to comment in more detail, but quick question: which version of Kamailio you are using? For 5.5.x branch some extensions were added to the topos module for SUBSCRIBEs:
+ This module is designed to work for presence (SUBSCRIBE-based) dialogs too. + The REGISTER and PUBLISH requests are skipped from processing Cheers, Henning -- Henning Westerholt – https://skalatan.de/blog/ Kamailio services – https://gilawa.com<https://gilawa.com/> From: sr-users <sr-users-boun...@lists.kamailio.org> On Behalf Of Marrold Sent: Wednesday, August 4, 2021 10:15 PM To: Kamailio (SER) - Users Mailing List <sr-users@lists.kamailio.org> Subject: [SR-Users] Issues with TOPOS when not relaying an in-dialog request Hi, I am currently using TOPOS to make Kamailio behave more like a B2BUA from the clients perspective. It's working well, however I have discovered a scenario where it fails. To aid with some interoperability I am sending (sl_send_reply) 200 OK to an in-dialog SUBSCRIBE request during a call. Once this has happened, the subsequent BYE from the B leg goes to the incorrect (Private) IP. If I disable this SUBSCRIBE, or relay it to the B leg, the BYE goes to the expected IP address. Does anyone know where I am going wrong? I have tried not calling record_route() for these messages but the result is the same. I've attached the ladder diagram of the call below. Note the subscribe is not relayed in this scenario. Thanks!
