[Serusers] Failure route processing

Hello there, We are trying to put together a script that executes an external program when receiving a certain failure code. The current script looks like: /*********************** start script ********************************/ route { [........] if (method==INVITE) { log(1, "INVITE\n"); t_on_failure("1"); }; [........] t_relay(); } [......] failure_route[1] { log(1, "Retry...\n"); if (status=~"48[0-9]") { log(1, "Called when busy!!!\n"); exec_msg('./switchboard_server/send_request "127.0.0.1" "9002" "STORE_SESSION" "$SIP_HF_FROM" "$SIP_HF_TO"'); }; append_branch(); t_relay(); break; } /***************************** end of script *****************************/ "exec_msg" does never get called with this configuration. What is the syntax to catch "48x" in failed replies? Thanks in advance, Jaime ******************************************************************************* Important.
