Hello, "write_sdp_pv" parameter helps to write a pvalue that includes modified sdp. Could you try it?

At first glance it looks simple. Considering the Data Lump feature in Kamailio, All changes in SIP body, does not apply quickly. So if we are using RTPEngine or RTPProxy, How we can get body message (Actually IP and port from SDP after rtpengine_manage function) before relaying message? Suppose i want get some information and run some extra things before relying message? I just added my extra things in t_on_reply block, but it's strange why it doesn't work before relaying! -Mojtaba Esfandiari.S _______________________________________________ Kamailio (SER) - Users Mailing List sr-users(a)lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users _______________________________________________ Kamailio (SER) - Users Mailing List sr-users(a)lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
