Hi, After upgrading to Kamailio v4.4, I receive the following error on boot: May 03 17:18:22 allegro-4.evaristesys.com /usr/local/sbin/kamailio[24972]: ERROR: rtpengine [rtpengine.c:2691]: select_rtpp_set(): script error-invalid id_set to be selected May 03 17:18:22 allegro-4.evaristesys.com /usr/local/sbin/kamailio[24972]: ERROR: rtpengine [rtpengine.c:2691]: select_rtpp_set(): script error-invalid id_set to be selected May 03 17:18:22 allegro-4.evaristesys.com /usr/local/sbin/kamailio[24972]: NOTICE: rtpengine [rtpengine.c:1788]: mod_init(): Default rtpp set 0 NOT found My rtpengine module config is: --- #!ifdef WITH_RTPENGINE #!subst "/RTPENGINE_SOCK/udp:127.0.0.1:5050/" modparam("rtpengine", "rtpengine_sock", "1 == RTPENGINE_SOCK") modparam("rtpengine", "rtpengine_disable_tout", 30) modparam("rtpengine", "rtpengine_tout_ms", 2000) modparam("rtpengine", "rtpengine_retr", 2) #!endif --- Furthermore, I have set_rtpengine_set("1") before every call to the rtpengine_* module function(s) in my route script. Subsequently to that, Kamailio starts normally and connects to rtpengine: May 03 17:18:22 allegro-4.evaristesys.com /usr/local/sbin/kamailio[24972]: INFO: rtpengine [rtpengine.c:2542]: rtpp_test(): rtp proxy <udp:127.0.0.1:5050> found, support for it enabled May 03 17:18:22 allegro-4.evaristesys.com /usr/local/sbin/kamailio[24975]: INFO: rtpengine [rtpengine.c:2542]: rtpp_test(): rtp proxy <udp:127.0.0.1:5050> found, support for it enabled May 03 17:18:22 allegro-4.evaristesys.com /usr/local/sbin/kamailio[24974]: INFO: rtpengine [rtpengine.c:2542]: rtpp_test(): rtp proxy <udp:127.0.0.1:5050> found, support for it enabled [...] It might be something on my end, but my guess is that in v4.4 there is a fixup that runs beforehand and looks for a default set. Strictly speaking, I don't need an explicitly identified set, since I'm only using one rtpengine instance. However, I explicitly specify it because I'd like the code to be open in the future to selecting a given rtpengine relay based on some criteria. -- Alex -- Alex Balashov | Principal | Evariste Systems LLC 1447 Peachtree Street NE, Suite 700 Atlanta, GA 30309 United States Tel: +1-800-250-5920 (toll-free) / +1-678-954-0671 (direct) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/
