[Serusers] SER + ser_acc_db_module

Hi, I apt-get installed ser_acc_db_module and tried to configure it. After restarting SER, SER simply doesn't reply to any REGISTER command. It seems to just ignore them so my phones cannot register. And I have no NAT issues either since I don't use NAT with SIP. Here's what I did at the configuration level: Firstly, I have added the following config to load and configure the acc_db module. <bunch of loadmodule statements> # ACC #loadmodule "/usr/lib/ser/modules/acc_db.so" #modparam("acc", "db_url", "sql://ser:heslo@localhost/ser") #modparam("acc", "db_flag", 1) #modparam("acc", "db_missed_flag", 1) #modparam("acc", "failed_transactions", 1) <bunch of modparam statements> Then, just after the "Record route" section and the "Loose route section", I have added this: # ----------------------------------------------------------------------- # Sets the acc accounting flag 4 billing info. # ----------------------------------------------------------------------- if( (method=="INVITE") || (method=="ACK") || (method=="BYE")) { setflag(1); }; Below I have my PSTN hookup, such as: # ----------------------------------------------------------------- # Pass on stuff going to PSTN to Asterisk # ----------------------------------------------------------------- if (src_ip==<trusted_customer_ip>) { if (lookup("location")) { t_relay(); break(); }; rewritehostport ("<asterisk_gw_ip>:5060"); if (!t_relay()) { # sl_send_reply ("403", "prout"); sl_reply_error(); }; break; }; Any ideas of what can be going on? As soon as I comment out acc-db related config and restart SER everything works smoothly again. Cheers, Jean-Michel.
