Hi, I'm interested in iptel.org ser configuration. The security setup is nice, where those iptel.org users that are not registered will not be able to call anywhere, and also those users that are not belong to iptel.org will also not permitted to make a call. But registered users from other domains can call registered iptel.org users. What should be the ser.cfg for me to achieve this?
