So, you've found yet another broken buggy system that doesn't follow
standards. Surprise, surprise. If you find the person who made the
system require no signal packets every 300ms can you find a 4x2 and wack
them around the head with it for me, please?

There is an option in spandsp itself to make it regularly repeat the
indicator signals, to tolerate this kind of broken behaviour. I'm not
sure if the Freeswitch module exposes that capability.
