Change the total in seconds in Hours, Minutes and Seconds, for example with 3 hours = 3600 * 3 = 14400. DNS SRV Record: This is known as resource record. Multiple records can be chained together in a cascade to rewrite URIs in deterministic ways. NAPTR implementations generally also implement EDNS as responses returning multiple NAPTR records are usually larger than the normal 512 byte packet size limit and would otherwise require a less efficient fallback to TCP rather than UDP. DNS AAAA Record: This record is used to map hostnames to IPv6 Address. So because we have the S designation in the flag field, our next step is to find the SRV record for the replacement _sip._udp.example.com.

NAPTR records are commonly used with SIP in conjunction with SRV records to discover what types of service are available for a name, (such as SIP, email or web) what name to use for an SRV lookup and (using the SRV record) what port and A records to use to find the IP for the service. The concept of S-NAPTR also simplifies the use of NAPTR by limiting the terminal flags only to "A" and "S". Because SIP clients don't all support SRV records, again in my experience less than half, using such records is better than nothing but is not a great solution for failover or load balancing. These resource names are not even in domain name syntax. If the weight is 1 or greater it is a relative number in which the highest is most frequently delivered i.e. SQL query is used to fetch data from the database.
