    <p>I am working with Freeswitch ESL client, I worked on originating call and establishing connection between two applications and making them communicate with each other. I have tried playing sound at one end and recording at the other, It is working fine now my requirement is to send dtmf at one end receiving at other end, I have tried following</p> <pre><code>private void sendDtmf(Channel channel) { SendMsg senDtmf = new SendMsg(); senDtmf.addCallCommand("execute"); senDtmf.addExecuteAppName("send_dtmf"); senDtmf.addExecuteAppArg("2174"); EslMessage response = sendSyncMultiLineCommand( channel,senDtmf.getMsgLines() ); if (response.getHeaderValue(Name.REPLY_TEXT).startsWith("+OK")) { System.out.println(this.getClass().getName() + " &gt;&gt; DTMF Send"); System.out.println("Resp: " + response.toString()); log.info(this.getClass().getName() + " &gt;&gt; DTMF Send"); } else { log.error(this.getClass().getName() + " &gt;&gt; DTMF failed :" + response.getHeaderValue(Name.REPLY_TEXT)); System.out.println(this.getClass().getName() + " &gt;&gt; DTMF failed :" + response.getHeaderValue(Name.REPLY_TEXT)); } } private void getdtmf( Channel channel, VoxtaMsg voxmsg) { SendMsg getDtmf= new SendMsg(); getDtmf.addCallCommand( "execute" ); getDtmf.addExecuteAppName( "play_and_get_digits" ); getDtmf.addExecuteAppArg("4 4 3 7000 # /tmp/sounds/test.wav /tmp/sounds/test1.wav dtmf \\d+"); EslMessage response = sendSyncMultiLineCommand( channel,getDtmf.getMsgLines() ); if ( response.getHeaderValue( Name.REPLY_TEXT).startsWith( "+OK" ) ) { System.out.println(this.getClass().getName()+" &gt;&gt; DTMF Received"); log.info( this.getClass().getName()+" &gt;&gt; DTMF Received" ); } else { log.error( this.getClass().getName() + " &gt;&gt; DTMF failed: [{}}" + response.getHeaderValue( Name.REPLY_TEXT )); System.out.println(this.getClass().getName() + " &gt;&gt; DTMF failed: [{}}" + response.getHeaderValue( Name.REPLY_TEXT ) ); log.debug("----------------------done-------------------------"); } } </code></pre> <p>but could not get any result, Do I need to configure any thing in dial plans, or my total approach is wrong?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
