Class AddressResolverKeepAlive

java.lang.Object

org.mjsip.server.sbc.AddressResolver

org.mjsip.server.sbc.AddressResolverKeepAlive

All Implemented Interfaces:

TimerListener

public class AddressResolverKeepAlive
extends AddressResolver

Class AddressResolverKeepAlive maintains an address binding. It maps socket addresses into other socket addresses and try to keep NAT connection open sending keepalive datagrams toward the remote UAs.

Class AddressResolverKeepAlive can be used to maintain a reference to the actual address to be used to reach a remote node, against to the address optained in other ways. For example, it can be used to maintain correct remote address mapping for symmetric NAT traversal.
