Hi,

our gnugk is unable to set up call to a public skycam at 203.174.20.80. 
The gnugk is in proxy routed mode:

[RoutedMode]
GKRouted=1
H245Routed=1
CallSignalHandlerNumber=15
AcceptNeighborsCalls=1
AcceptUnregisteredCalls=1
RemoveH245AddressOnTunneling=1
RemoveCallOnDRQ==0
DropCallsByReleaseComplete=1
SendReleaseCompleteOnDRQ=1
SupportNATedEndpoints=1
SupportCallingNATedEndpoints=1
TreatUnregisteredNAT=1
TranslateFacility=1
ActivateFailover=1
EnableH450.2=1

[Proxy]
Enable=1
ProxyForNAT=1

[RasSrv::ARQFeatures]
CallUnregisteredEndpoints=1
ArjReasonRouteCallToGatekeeper=0

The trace logs initially indicated that the call is NAT type 0 and so 
continues to normal call setup but very quickly the call drops and CDR 
generated. Only after this the gnugk drops another called ip which is 
behind NAT and generate another CDR. Please see below trace logs:

This is suspicious but i'm unsure if it's normal call dropping. Thanks for 
your advice.
