Hi, I try to run this module, but unsuccesfully. Can you give me some advices? How I can start the pdb_server? I compile and install it, but don´t know how get it run. I must add loadmodule="pdb.so" in kamailio.cfg file? When I did it, kamailio didnt start. Starting end with error. I think that there missing bracket : # query external service for routing information if (!pdb_query("$rU", "$avp(i:82)")) $avp(i:82) = 0; # default routing } cr_route("$avp(i:82)", "$rd", "$rU", "$rU", "call_id"); Thank you for your answer. Have a nice day.
