[SR-Users] Msilo not delivering message (status 408)

I removed the localhost listeners on TCP and UDP, and, as I suspected,
Kamailio doesn't seem to like that.
Why isn't kamailio sending the message back through the TLS socket?


NOTICE: <script>: -------------------------MESSAGE PROCESSING: dumping
offline messages
ERROR: tm [ut.h:343]: uri2dst2(): no corresponding socket for af 2
ERROR: tm [uac.c:266]: t_uac_prepare(): t_uac: no socket found
