[SR-Users] Pdb module

[Ahmed]

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.
