If you want to use the "i" and "e" flags, you must name your logical interfaces "internal" and "external" respectively, as in: ./rtpengine ... --interface=internal/192.168.100.1 --interface=external/192.168.50.1 ... Alternatively if you wish to retain and use the more free-form interface names, you must use the "direction=..." option in your calls to rtpengine_*(), but you'd need a more recent version of the rtpengine module for this to work. cheers _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
