For the time being try putting 212.41.253.181in hostname= line in ur sip<br>config and it should work . Also check if you /etc/resolv.conf has correct<br>dns list ( i guess it does bcoz OS can<br>resolve) . Also check /etc/asterisk/dnsmgr.conf .
<br><br>Here's example :<br>[general]<br>enable=yes ; enable creation of managed DNS lookups<br>refreshinterval=1200 ; refresh managed DNS lookups every <n> second<br><br><div><blockquote class="gmail_quote" style="margin-top: 0; margin-right: 0; margin-bottom: 0; margin-left: 0; margin-left: 0.80ex; border-left-color: #cccccc; border-left-width: 1px; border-left-style: solid; padding-left: 1ex">
