Hi All; Finally I succeeded to use the SQLAuth after recompiling the gnugk (but this time I installed postgresql firstly). When the endpoint (which is behind NAT, so it has a private IP address), trying to register at gnugk, then I get the following message: RRJ|62.150.228.104|gwbilal:h323_ID=123456:dialedDigits|terminal|invalidCallSignalAddress; Then I changed the configuration and I added SupportNATedEndpoints=1 under the RouteMode section, the RRJ message become as following: RRJ|62.150.228.104|gwbilal:h323_ID=123456:dialedDigits|terminal|resourceUnavailable; Really I beleive the problem related to NAT settings that I have to do it, and could be related to something else, but I am not able to know. Can someone advise me to help in fix it? Appreciate the help.
