Here is the sticky part. Nortels general policy is to 'upgrade to the most current level'. I have found that to be an upgrade right into the toilet, upon occasion. If he has access to Nortels site, presumably he has free tech support from them. If he is willing to call them and ask for the patch (it may be outdated enough now that it is off the website), that would be the cheapest route. If not, an upgrade may be your only option. If it was mine, I would get the s/w level to 2.10.06 or 2.10.08 and put in the A7 patch. Those rls were stable. 2.00.47 had issues including night CCR not working. At rls 3, Nortel actually came out with a new, physical box as well. I'm always leary of upgrading an old box that may or may not work well with new s/w that was designed for a new box.
