You must filter the events on each channel, so you don't receive events on the outbound thread that are being generated on the inbound call thread. To accomplish this you have several options: use myevents on the outbound socket, or add a filter based on the call uuid. For the outbound call, you can have something like: final org.freeswitch.esl.client.inbound.Client client = new org.freeswitch.esl.client.inbound.Client(); client.connect("localhost", 8021, "ClueCon", 2); ... client.addEventFilter("Unique-ID", uuid); For the inbound call, in the class that extends AbstractOutboundClientHandler you can have something like: @Override protected void handleConnectResponse(ChannelHandlerContext ctx, EslEvent event) { String uuid = event.getEventHeaders().get(""Unique-ID"); sendSyncSingleLineCommand(channel, "filter Unique-ID " + uuid); ... } -----Original Message----- From: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Gilbert Amar Sent: Thursday, January 03, 2013 5:43 PM To: 'FreeSWITCH Users Help' Subject: [Freeswitch-users] mod_event_socket event with no eventname Hello, I am using mod_event_socket org.freeswitch.esl.client-0.9.2 and FreeSWITCH Version 1.2.5.3.
