5060 is Closed at my end of at ISP end as Server got Internet BUT cant register with VOIP provider ??

Same Provider settings works perfectly on another server.

please remember to post whether there is any other software installed on the box when you create your "about my server" blurb.

it looks like you had the server scan itself

on a freshly installed server that is exactly the reading i get as well.

but since your server does not register to itself via SIP, that doesn't really mean much

you need to use SIP debug to find out why your provider refuses you registration (nmap will apparently view SIP closed even when it works, and it makes no difference if SIP on YOUR machine is closed, you are contacting another server for sip, and it is highly unlikely that SIP is closed at your provider ... but if you use SIP debug, you may find out!)
