Appreciate everyone's response here! Fortunately we are right in the middle of setting up a xen box which will hold a few other servers one of which is in fact a dns server with caching/recursion for local net clients. I'll implement this with an extended caching time. /etc/host.conf does have hosts before bind, so I suppose I could also add entries for the sip providers in the register => lines but I hate to do that incase those ip's change (however unlikely) it would be a bugger for someone else to chase down. Checking into the syntax for register in sip.conf its not actually clear if it supports an ip instead of a fqdn. That would also be easier to track down by someone else if need be, can this be done? If so although the reg attempt would fail this would alleviate a dns issue which I assume is the only issue (not failed reg attempts as well). Once I get back onsite, or can connect remotely I will test this all and post back for confirmation. Thanks everyone! jlc _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
