Bell has been doing a lot of testing on their DPI system as of late. I
would suspect that this is what caused this.
As a DSL provider we have seen tonnes of NOC messages come in from Bell
lately to open up maintenance windows with a description of
"reconfiguration, software, moving the fiber from the ERX to a DPI node".
So it looks like Bell is going to start shaping the traffic on Sympatico and
business customers in a similar fashion to what Rogers has been doing for
some time now.
Thank god their DPI doesn't affect the wholesale DSL base.

I **was** having similar problems as all you guys did. The problem seems
to have rectified itself. I'd guess something GOT screwed at their end,
though I doubt they were TRULY blocking packets "knowingly". I'd suspect
they were doing their own internal testing with certain firewalls/new
software. However the problem was also the DSL modem was not syncing in
properly etc. I'd say network glitch at their end.

I am having the same problem, I am using both trixbox and elastix for my
personal home systems with bell DSL.
this has been going on for a month now on and off, but today it is really
bad all was fine yestarday but today none of my calls are going out, I
have
not changed anything as of yestarday. Incoming calls are fine and routs
the
way it should. I have a backup line so I have some time to investigate
this.

I had three customers call me today, all of them on Bell business DSL,
complaining that they could receive calls, but couldn't place outgoing
calls.
The phones would register, the voicemail indicators worked fine, the BLF
lamps lit and extinguished when they should, but any outgoing calls timed
out.
Further analysis showed that outgoing INVITEs from the customer site were
being dropped, but REGISTER, NOTIFY, and media packets made it through
without difficulty.
This happend to all my customers using Bell, and none of the customers
using
anyone else for internet connectivity. I have eliminated hardware
failure
by
authenticating to a different DSL provider using the same equipment (it
worked fine with a Packetworks account).
Has anyone else experienced the same problem?
I would like to think that this is just an oversight on their part, so I
am
following up with them. If it is intentional, is there any rules against
it?
Rogers portable internet seems to have the same "filter", except that
theirs
blocks incoming INVITES as well.
