I'm not a DNS guru, but this is what I would do...

) Start with "whois" to determine the names of the authoritative name 
servers for the domain:

 	whois example.com

This shows that A.IANA-SERVERS.NET and B.IANA-SERVERS.NET are the 
authoritative name servers.

) Query each of the name servers to see who they think are the name 
servers:

 	dig @A.IANA-SERVERS.NET example.com ns
 	dig @B.IANA-SERVERS.NET example.com ns

This shows that a.iana-servers.net and b.iana-servers.net. The difference 
in case is not significant.

) Query each name server to see if they can resolve the host name:

 	dig @a.iana-servers.net whsvoip.example.com
 	dig @b.iana-servers.net whsvoip.example.com

) If you are trying to use SRV records, use these queries:

 	dig @a.iana-servers.net srv _sip._udp.example.com
 	dig @b.iana-servers.net srv _sip._udp.example.com

) And just for fun, repeat the whole exercise on the other host. You're 
looking for failures or inconsistencies that may explain why you getting 
different behaviors.
