Hi Guys,
having pretty much the same issue as this guy:
https://community.sophos.com/products/unified-threat-management/f/62/t/57282
Phone sits on "Discover IPOffice IP address"
I have configured the H323 and SIP sections as I thought it may have something to do with that
I have also bounced the UTM as I have read it can be funny with this, all ports are allowed both ways?
Turned off webfiltering and all other filtering/ protection, but nothing seems to be working
from what I have read it could have something to do with ALG needing to be turned off.
TIA
