Any ideas?, there is no _q931 option in the SVR record for the Windows 2000 Servers I have (sapanish with SP2 applied), I know maybe this is not the right place to ask for this, but i thought maybe somebody had this situation too.
What I¦m trying to do is a Gatekeeper to Gatekeeper connection over the internet, with e-mail address calling rule active.
You're right. As long as your configure the destination, it works fine. The ideal setting, and its supposed to work this way, is that you can set the _q931 record and let DNS resolve the destination, so that you don't have to configure an explicit destination for the email address rule.
