<div dir="ltr"><div><div><div>I understand that I can have multiple bridge statements after my initial bridge, however this is specifically for detecting when a device fell off the network and the registration hasn't timed out. We want the behavior to be different than if the device was still on the network and it just rang for some time period and timed out and moved on to the next bridge statement, which is why I need transfer_on_fail.<br><br></div><div>In regards to "hangup_on_bridge", I figured out later that it doesn't exist. I pulled that straight out of the documentation for transfer_on_fail, as with everything I was trying initially.<br><br> <a href="https://wiki.freeswitch.org/wiki/Variable_transfer_on_fail">https://wiki.freeswitch.org/wiki/Variable_transfer_on_fail</a><br></div><div><br><br>I think I figured out the problem, the condition for the transfer_on_fail wasn't being met with ${originate_disposition}, which is also straight out of the documentation for transfer_on_fail. It looks like the conditions get evaluated only at the beginning when the dialplan is called, not when that part of the dialplan gets hit? So at the time the dialplan is initially called, ${originate_disposition} isn't set and didn't match the Regex for it to pass the condition. I changed the condition to destination_number and it works now.<br></div><br></div>The only part I couldn't get working is transferring to a different context within transfer_on_fail, for example:<br><br> <action application="set" data="transfer_on_fail=PROGRESS_TIMEOUT auto_cause xml error"/><br><br></div>If I put the PROGRESS_TIMEOUT extension within the "error" context, it doesn't work. Not sure what's going on there, but it's not a big deal. It works fine like this ...<br><div><div><br><document type="freeswitch/xml"><br> <section name="dialplan" description="Dial Plan for FreeSWITCH"><br> <context name="default"><br> <extension name="call to 12225551212"><br> <condition field="destination_number" expression="12225551212"><br> <action application="set" data="bypass_media=true"/><br> <action application="set" data="continue_on_fail=true"/><br> <action application="set" data="hangup_on_bridge=true"/><br> <action application="export" data="leg_progress_timeout=3"/><br> <action application="set" data="transfer_on_fail=PROGRESS_TIMEOUT auto_cause xml"/><br> <action application="bridge" data="${sofia_contact(12225551212@switch.local)"/><br> </condition><br> </extension><br> <extension name="PROGRESS_TIMEOUT"><br> <condition field="destination_number" expression="12225551212" continue="false" break="on-true"><br> <action application="bridge" data="sofia/external/<a href="tel:12345551212" value="+12345551212" target="_blank">12345551212</a>@switch2.local"/><br> </condition><br> </extension><br> </context><br> </section><br></document><br><br><div><br><br></div></div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Nov 25, 2015 at 3:07 PM, Brian West <span dir="ltr"><<a href="mailto:brian@freeswitch.org" target="_blank">brian@freeswitch.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">And for those wondering:<div><br></div><div>
