Hi, Solved this problem. #!define DBURL "postgres://asterisk:password@Float.ing.IP.pgpool:9999/kamailio" #!ifdef WITH_ASTERISK #!define DBASTURL "postgres://asterisk:password@Float.ing.IP.pgpool:9999/asterisk" #!endif #!endif I have changed below as follow. #!define DBURL "postgres://asterisk:password@Float.ing.IP.pgpool/kamailio" #!ifdef WITH_ASTERISK #!define DBASTURL "postgres://asterisk:password@Float.ing.IP.pgpool/asterisk" #!endif #!endif I defined the port as 9999 for pgpool2postgres that was not correct. I removed the definition port as 9999 for pgpool2postgres that is working all and fine. I do not know the reason. By the way I will report to the ALL. Thank you for kamailio and Daniel, ALL!
