I don't have any details. Still trying to figure out what the problem is. We aren't getting complaints of not being able to connect to our network by our customers, but we are seeing a lot of problems between us and our upstream ITSP vendors. Our ITSP vendors also seem to be having a lot of problems with call setups.
First, be careful about forwarding internal mail out to mailing lists; you can leak things that way which people might prefer you didn't. Second, if XO is involved, you should see this week's NANOG archive, wherein we discuss the fact that XO has been known to put in blocks down to the IP/port level without notice; it's possible that might have some bearing on your problems. This was specifically mentioned in the context of SIP. Cheers, -- jra -- Jay R.
