Is the callid in hash table? Yes --> Don't resolve DNS and send it to the stored IP NO --> Use DNS to send it and store the IP using onsend_route If you set the autoexpire of keys to 3-4 secs it will work well. cheers, Jon _______________________________________________ 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
