Hi, i ´ve just setup a child gk and can easy circumvent the authorisation mechanism of the parent gk by setting up a number as i like e.g. 0815 (endpoint) and set a prefix to this number. So it´s easy to register this number without authorisation and place or receive a call. For unattendend proxy server this is not a glorious. To prevent the child gk setting up a prefix i guess there is a option at the gatekeeper.ini but i found nothing to force the child gk sending the RRQ to the parent gk (except i make a setup at the child gk, which is easy to circumvent) any idea? please help. big thx TOM ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.
