maybe you have just to wait a bit longer. When I run:
dig @126.96.36.199 allcallz.com
dig @188.8.131.52 allcallz.com
to query your dns server, I get a correct response on both IP addresses so your dns servers are working and are reachable. I'am not able to get a response when I use the ns1 and ns2 subdomains which indicates a problem with the glue records. Please contact the provider were you ordered the domain name allcallz.com again and ask them to verify that the glue records ns1.allcallz.com and ns2.allcallz.com are really created and that they point to the two IP addresses of your server.
