This is not a "Min TTL" but a "Minimum Negative TTL" instead.

It looks like that your $ORIGIN is "stor.company.com". Start tidying
your zone file by reading the section 3.2 "Zone file style guide" of
RFC 1912 "Common DNS Operational and Configuration Errors" available at
http://www.rfc-editor.org/rfc/rfc1912.txt . You don't have to specify
your $ORIGIN every time so the line quoted above can be edited as

sip                     IN A 10.10.10.10

sip.stor.company.com isn't a subdomain but a hostname which is used as
a nameserver for subdomain.stor.company.com.

Which servers are listed as a resolvers on your machine on which you're
running dig? If this is an UNIX machine, please show us your
/etc/resolv.conf and comment it.

Have you reloaded the zone stor.company.com properly?
