Dear all, I am getting 404 User Not Found whenever i received a NOTIFY method. Don't know what is wrong with it. All i did in the ser.cfg was a simple lookup("location") but it seems that they cannot find the record in the location table. I have check and confirm that the user location record is in the table. What is going on ? What are they suppose to compare or what is the lookup suppose to do ? What i cannot understand is why are there no if else to take in method==NOTIFY . Please help. Regards, Sam
