Hello,
check the H245 communication. If both endpoints send H245 to gatekeeper
set H245Routed=1 in gnugk.ini. Are both endpoints on the same interface of
gnugk ? If not. Is there a firewall or nat. Check the filter setting. Some
endpoints by default request H323V2 FastConnect when initiaiting a
connection. Disable this on endpomits.
Cheers,
Vladimir
