Determines whether, if no NAPTR (SIP) or SRV (SIP and H.323) records
have been found for the dialed alias via this zone, the Expressway 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
Expressway believing the search was successful and forwarding calls to
this zone, and the call will fail.
