Hello, did you add some users into database? Please follow the guidelines from http://www.iptel.org/ser/bugs/ and send us the result. We can't guess everything what happen into your system only from config file. You have commented some global parameters and that changed the behavior SER should have with default config file -- you even commented the number of children that means ser listens only on first network interface (I have to double check it, but it should be like that), and that is usually 127.0.0.1. We need the log messages, network dumps and so on ... Regards, "Daniel
