[Freeswitch-users] continue_on_fail triggered by NORMAL_CLEARING

We have a freeswitch box acting as a DR backup to the live system (called
"freedom2" because that is what our vendor calls it). We are using
continue_on_fail to catch conditions when the live system is down in order
to forward it to a DR fifo.
Occasionally (rarely) I'm getting a BYE back from the live system and the
call is getting sent to DR and I can't figure out why this is happening.
Would someone please take a glance at this and help me understand if I'm
doing this wrong or if FreeSWITCH is misbehaving here?
We are running FreeSWITCH Version
1.6.20+git~20180507T185611Z~43a9feb7f8~64bit (git 43a9feb 2018-05-07
18:56:11Z 64bit)
/proc/version: Linux version 3.16.0-6-amd64 (debian-kernel at lists.debian.org)
(gcc version 4.9.2 (Debian 4.9.2-10+deb8u1) ) #1 SMP Debian
3.16.56-1+deb8u1 (2018-05-08)
/etc/debian_version: 8.10
Here is the dialplan in question:
<extension name='freedom2 (default)' continue='false' priority='99'>
<condition field='destination_number' expression='^\+?1?(\d+)$'>
<action application="log" data="ALERT INBOUND ${sip_gateway} -> $1 ->

<action application="set" data="fifo_chime_freq=30"/>
<action application="set" data="fifo_music=$${hold_music}"/>
<action application="fifo" data="q1 in"/>
</condition>
</extension>
Here is an example of a call that got sent to the live system, even though
the call appears to have ended in NORMAL_CLEARING. I started with the BYE
packet back from the live system and cut it off at the point that the log
application executes on the line after the bridge.
I attempted to replace instances of public IP and phone #'s with
placeholders.
