Have configured GnuGK v2.2.1.2 - stock binary from the gnugk.org site to pass calls into a Cirilium Gatekeeper as below:- [Gatekeeper::Main] Fourtytwo=42 Name=MYGNUGK EndpointIDSuffix=_gk1 [GkStatus::Auth] rule=allow Shutdown=allow RoutedMode] GKRouted=1 H245Routed=0 CallSignalPort=1720 DropCallsByReleaseComplete=1 SendReleaseCompleteOnDRQ=1 ForwardOnFacility=0 SupportNATedEndpoints=1 [RasSrv::PermanentEndpoints] ; For gateway 1.2.3.4=CIRILIUMGK1;0123 [RasSrv::RRQFeatures] OverwriteEPOnSameAddress=1 AcceptEndpointIdentifier=1 AcceptGatewayPrefixes=1 [RasSrv::ARQFeatures] ArjReasonRouteCallToSCN=0 ArjReasonRouteCallToGatekeeper=0 CallUnregisteredEndpoints=1 RemoveTrailingChar=# The call with prefix 0123 is being rejected by the CIRILIUMGK1 when made from any registered endpoint in MYGNUGK. Only the MYGNUGK's IP Address is entered into the CIRILIUMGK1's configuration. There is no authentication required. Unfortunately, when the Cirilium's logus were checked, we find that the calling endpoint's IP address appears in the messages sent to the Cirilium GK and not that of the MYGNUGK which has been authorised. Can somebody kindly explain how to get thru' this problem and explain if and how the following can be useful:- [RoutedMode] RemoveH245AddressOnTunneling=1 ScreenDisplayIE=MyID ScreenCallingPartyNumberIE=??? ScreenSourceAddress=MyID ShowForwarderNumber=0 And whether MyID is the h323-alias or IP address? The Manual is very brief on the above points.
