The example configuration files in the distribution have it set up and ready to use if you add the line "#!define WITH_MULTIDOMAIN" The important bit for your scenario is in the example config: # ----- domain params ----- #!ifdef WITH_MULTIDOMAIN modparam("domain", "db_url", DBURL) # register callback to match myself condition with domains list modparam("domain", "register_myself", 1) #!endif That section tells the domain module to use the database, and to include the domains loaded from there when matching the special keyword "myself". The example config files also set up other modules (like user location module) to be domain aware as well. In this setup you do not need to restart kamailio when you add or remove domains.... but you do need to tell it to reload the domains from database as Kamailio holds a cached copy of the list in memory.... so when you make a database change then do "kamctl domain reload". You can also run "kamctl domain show" to see what domains are currently listed in memory.
