Is your ISP doing DNS resolutions for you? If yes, then I also think it has something to do with the DNS queries which hangs asterisk. But it should not bring the server down.
On CentOS, caching name server should be very easy to install by doing: yum install caching-nameserver I don't remember if it also sets up the required config files.

I remember at one point that trixbox would hang if you had any SIP trunks configured and you lost internet connectivity, but a caching nameserver on the same box tended to help. -- Thanks, --Warren Selby http://www.selbytech.com -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
