Change subject: Add NAPTR preference failover test.
......................................................................


Add NAPTR preference failover test.

This test has two NAPTR records. The one with the lower preference value
points to a TCP SRV record that does not exist. The one with the higher
preference value points to a UDP SRV record that will resolve properly.

A SIPp scenario is running on a UDP port and receives the call since
Asterisk fails over to UDP after the TCP SRV lookup fails.
