Hi Isaac, On 5/31/13 11:55 PM, Isaac A. McDonald wrote: You can build the routing logic statically in kamailio configuration file. But in many cases you can use a module that loads the routing rules from database. It is where siremis can help, by managing those rules in database. Then you can send a MI/RPC command to kamailio to tell to a module to load its rules from database, without need to restart. For example, pdt module, it loads its rules to translate a prefix to a domain from pdt table at startup. If you change something in database, then you can send a command using kamctl to reload all the rules from database. The configuration file is not affected at all by such operations. Regards, Ramona
