Hi, thanks for the reply...
I thought this was solved as the client has been stable for a few weeks but had another hiccup the other day so I'm back on site looking into things.
Looking through logs for other branches reveals a lot of different errors using any number of different ports that I didn't know Mitel even used... the branch I am at now, however, only seems to have errors on port 5570
here's some of the log for one of the branches:
