Class DefaultAddressResolver

java.lang.Object

android.gov.nist.javax.sip.DefaultAddressResolver

All Implemented Interfaces:

AddressResolver

public class DefaultAddressResolver
extends Object
implements AddressResolver

This is the default implementation of the AddressResolver. The AddressResolver is a NIST-SIP specific feature. The address resolover is consulted to convert a Hop into a meaningful address. The default implementation is a passthrough. It only gets involved in setting the default port. However, you can register your own AddressResolver implementation Note that The RI checks incoming via headers for resolving the sentBy field. If you want to set it to some address that cannot be resolved you should register an AddressResolver with the stack. This feature is also useful for DNS SRV lookup which is not implemented by the RI at present.
