Determines whether, if no NAPTR (SIP) or SRV (SIP and
H.323) records have been found for the dialed alias via this
zone, the Cisco VCS will then query for A and AAAA DNS
records before moving on to query lower priority zones. If A
and AAAA records exist at the same domain for systems
other than those that support SIP or H.323, this may result in
the Cisco VCS believing the search was successful and
forwarding calls to this zone, and the call will fail.
