hi all,
when I set CallSignalHandlerNumber(in file *.ini ) 2,I can connect 2 Tcp
connection(though Gk don't use the second one when the seconf call
arrive).the value of CallSignalHandlerNumber seems having something to do
with the number of the TCP connection.
by the way,"debug trc 6" can print out nothing useful information(maybe I
can't understand them),give me some more suggestion,any suggestion.
thanks in advance.

Do a debug trc 5 on your gatekeeper to log what's going on.
