Hey krishnan,<div><br><div>Everything happens for a reason. The most intuitive cause of this issue seems to be network change. Can you confirm that no change in networking happened! because your server is sending register requests but not getting responses. Meanwhile the same server replying to scenarios2 can imply either at your or the server end is blocking. There could be NAT issue if its not firewall. </div>
<div><br></div><div>1- Make sure you can ping from your asterisk server to Registrar server. Do a traceroute as well.</div><div>2- Check for any firewalls in between (could be fail2ban/ iptables)<br>3- Verify that no network changes occured.</div>
<div>4- Call your service provider and tell them that their server is not talking to your server any more. :P</div><div><br></div><div>best of luck. </div><div><br></div><div>-Sammy</div><div><br></div><div><div class="gmail_quote">
