<div>&nbsp;</div>


<div>I&#39;m experimenting with the piped failover on the latest master. I want a failover to stop gw hunting and return from bridge when B-leg receives a specific disconnect code e.g. USER_BUSY or NO_ANSWER, but while it works as expected with error channels in console i.e.:</div>


<div>&nbsp;</div>


<div>freeswitch@internal&gt; originate {fail_on_single_reject=CALL_REJECTED:USER_BUSY}error/NO_ANSWER&#124;error/USER_BUSY&#124;error/CALL_REJECTED 999<br/>

-ERR USER_BUSY</div>


<div>&nbsp;</div>


<div>

<div>freeswitch@internal&gt; originate {fail_on_single_reject=CALL_REJECTED:NO_ANSWER}error/NO_ANSWER&#124;error/USER_BUSY&#124;error/CALL_REJECTED 999<br/>

-ERR NO_ANSWER</div>


<div>&nbsp;</div>


<div>it does not work in dialplan:</div>


<div>&nbsp;</div>


<div>

<div>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;extension name=&quot;outbound&quot;&gt;<br/>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;condition field=&quot;destination_number&quot; expression=&quot;^&#92;d{7}&#36;&quot;&gt;<br/>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;action application=&quot;set&quot; data=&quot;bridge_answer_timeout=120&quot;/&gt;<br/>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;action application=&quot;set&quot; data=&quot;continue_on_fail=NORMAL_TEMPORARY_FAILURE:NO_ROUTE_DESTINATION:CALL_REJECTED&quot;/&gt;<br/>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;action application=&quot;set&quot; data=&quot;fail_on_single_reject=USER_BUSY:NO_ANSWER:NO_USER_RESPONSE:RECOVERY_ON_TIMER_EXPIRE:ORIGINATOR_CANCEL&quot;/&gt;<br/>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;action application=&quot;set&quot; data=&quot;bridge_early_media=true&quot;/&gt;<br/>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;action application=&quot;set&quot; data=&quot;hangup_after_bridge=true&quot;/&gt;<br/>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;action application=&quot;odbc_query&quot; inline=&quot;true&quot; data=&quot;route_out&quot;/&gt;<br/>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;action application=&quot;bridge&quot; data=&quot;&#36;{bridge_to}&quot;/&gt;<br/>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;action application=&quot;hangup&quot; data=&quot;&#36;{last_bridge_hangup_cause}&quot;/&gt;<br/>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;anti-action application=&quot;hangup&quot; data=&quot;INVALID_NUMBER_FORMAT&quot;/&gt;<br/>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;/condition&gt;<br/>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;/extension&gt;</div>


<div>&nbsp;</div>


<div>or when included in bridge dialstring:</div>


<div>&nbsp;</div>


<div>&lt;action application=&quot;bridge&quot; data=&quot;{fail_on_single_reject=USER_BUSY:NO_ANSWER}&#36;{bridge_to}&quot;/&gt;</div>


<div>&nbsp;</div>


<div>i.e. it tries *all* gateways in the dialstring and ignores returning codes completely.</div>


<div>&nbsp;</div>


<div>I tried the same test when remote gateways were just hanging up with USER_BUSY code on receiving calls, but it did not affect the same negative result - all remote peers were tried in order and return code were ignored.</div>


<div>&nbsp;</div>


<div>I had the same experience with ver 1.2, but that time set continue_on_single_reject=err1,err2,err3 in dialplan worked for me flawlessly. However the same approach does not work for 1.5 and 1.4. Has anyone succeded in getting it to work as expected?</div>
