Hi Marc,

That's definitely strange.  I have one other thought as to how this could
have happened, although it's not likely.  I haven't tested it but I think
it's possible to override your PIC with the 1010 prefix then the second
carriers CIC.  They used to use it for cheap LD services but I don't hear
much about that anymore.

As for why your PIC order didn't catch the traffic, IIRC my experience has
been that when I add services to my account, like a new 1FL for a fax
machine, I have to issue a new PIC order for that circuit.  I've only had
to do it a few times so you've probably got more experience in that area
than me.

If I had to bet, I'd lean the same way as you.  It's probably a programming
issue on the CO side.  Maybe a typo caused one channel from someone else's
circuit to be added to a trunk group on your account.  It seems like that
would be easier to do if you had NFAS on the PRI.  You might check your PRI
Debug for an error that says something "D channel says I have media on
channel 49 but channel 49 could not be found."  That's what I've seen on my
systems in the past when the CO has more channels in a trunk group than I
have defined on my side.

Good luck getting to the bottom of that.  I'd be curious to hear how it
settles out.  Usually you get a call back from Bell saying that they looked
into it and nothing was wrong on their side, after which, the problem
disappears.  I usually interpret that to mean that the tech found the
problem and fixed it but didn't want to 'fess up that it was his issue.


All the best,
Dave
