Thank-you so much for your help. Simply by switch the port number (unknown to me until you've pointed out just now) saved me from all the headache I've had for the longest time. Don't get me wrong, but I could just kiss you right now!! :> Anyway, there are 2 things that I would like to understand from here on. 1) Under the [Gatekeeper::Main] section, there is an option of which I've configured "EndpointSignalPort=1720". Is this option mainly target on the port 1720 which allows all endpoints to register onto this gk by port 1720??? Does this option have anything to do with the default 1721 port issue of which you've mentioned???? 2)If point 1 has nothing to do with the default gk listening 1721 port, is there a way to configure this to some other ports?? Thanks again for your help!!! :> Quoting Zygmuntowicz Michal <m.zygmuntowicz@xxxxxxx>: > 2. Did you specify port 1721 (not the default 1720) in the permanent > endpoint > entry. The gatekeeper listens to ports 1721 by default. > 3. See the point 2. Also you may need to set AccepUnregisteredCalls or > AcceptNeighborsCalls flag. > ------------------------------------------------- This mail sent through IMP: http://horde.org/imp/ ------------------------------------------------------- This SF.Net email is sponsored by the new InstallShield X. >From Windows to Linux, servers to mobile, InstallShield X is the one installation-authoring solution that does it all.
