All Implemented Interfaces:

io.netty.channel.ChannelHandler, io.netty.channel.ChannelInboundHandler

class OutboundClientHandler
extends AbstractEslClientHandler

Specialised AbstractEslClientHandler that implements the base connecction logic for an 'Outbound' FreeSWITCH Event Socket connection. The responsibilities for this class are:

• To send a 'connect' command when the FreeSWITCH server first establishes a new connection with the socket client in Outbound mode. This will result in an incoming EslMessage that is transformed into an EslEvent that sub classes can handle.

Note: implementation requirement is that an ExecutionHandler is placed in the processing pipeline prior to this handler. This will ensure that each incoming message is processed in its own thread (although still guaranteed to be processed in the order of receipt).
