Class DNSAddressResolver

java.lang.Object
  org.mobicents.servlet.sip.core.DNSAddressResolver

All Implemented Interfaces:

gov.nist.core.net.AddressResolver

public class DNSAddressResolver
extends java.lang.Object
implements gov.nist.core.net.AddressResolver

The Address resolver to resolve proxy domain to a hop to the outbound proxy server by doing SRV lookup of the host of the Hop as mandated by rfc3263.
some of the rfc3263 can hardly be implemented and NAPTR query can hardly be done since the stack populate port and transport automatically.
