The Service Registry is part of a Service Discovery framework the SBC uses to determine the IP addresses for certain services. Refer to Service Discovery for Trap Target Destinations and RAMP Registration for more information.

  • True
  • False (default)
Round Robin

Specifies whether the order in which name servers are queried should be random. The options are:

  • True   (default) the SBC sends a resolve query to contact the configured name servers in a random order until the SBC receives a response. The order changes for each query.
  • False –  the SBC sends a resolve query to contact the configured name servers sequentially until the SBC receives a response.
TtlSpecifies the maximum time-to-live, in seconds, to use when resolving an entry. The range is 1 to 4294967295. The default is 30 seconds.

If the TTL of an entry in the name server is greater than this value, this value is used instead.
