The module replaces the common system dns resolver functions from core with the DNSSEC wrappers provided by libval. Practically, by loading the module, Kamailio will make use of extensions to DNS which provide origin authentication of DNS data, authenticated denial of existence, and data integrity. There is no module parameter that should be set nor function that has to be executed by the configuration file. Existing SIP server deployments can be updated to use DNSSEC by loading this module and setting appropriate DNS server to the operating system. Installing libval can be done from https://www.dnssec-tools.org. More details about DNSSEC are available at: http://en.wikipedia.org/wiki/Domain_Name_System_Security_Extensions.
