Hello, are you doing maybe two operations on the body in a row? This will create issues, refer to the FAQ: https://www.kamailio.org/wikidocs/tutorials/faq/main/#why-body-or-other-parts-of-the-sip-message-appear-multiple-times
Have a look e.g. to this older issue for a recommendation involving branch_route with rtpengine. https://github.com/kamailio/kamailio/issues/3275 Cheers, Henning > -----Original Message----- > From: msd.mazarei--- via sr-users <[email protected]> > Sent: Montag, 13.
