[OpenSIPS-Users] Intercept 477 on TCP closed

Using OpenSIPs 3.0.3
I'm dealing with a client device with a faulty network, they are using a
softphone WebRTC client and the TCP connections disappear sporadically.
When the media server issues a RE-INVITE session timer OpenSIPs discovers
the closed TCP connection and returns 477 to the media server. In this case
the media server is FreeSWITCH which promptly ignores the
non-standard session timer response and the call hangs. I want to close the
call immediately in this situation as there is no way I can see to
reestablish the connection. The call is typically bridged on the media
server so the other call leg is left dangling indefinitely so I need to
find a way to kill the session.
Reading RFC4028 <https://tools.ietf.org/html/rfc4028#section-10> the only
response codes that should trigger a BYE are 408/481 so my aim is to
intercept the 477 and alter it. Unfortunately I have been unable to
intercept it within my OpenSIPs config as the messages don't hit
failure_route or similar. Am I missing a trick? Is there somewhere where
these can be intercepted or should I be looking into a solution on the
media server instead?
