> technicians can only bring one replacement at the time so if their guessing of the faulty part is wrong, they have to come back another day. We've a BT maintained phone system and a few years ago when it was a Nortel BCM the engineer had a van full of parts and could resolve pretty much any problem on his one and only visit. We 'upgraded' to an Avaya IPO a couple of years ago. When it developed a fault the engineer who came out said they don't carry any spares any more. Because of the fault it wasn’t clear which part had failed so guessed which of two cards it was, that had to be sent to our site from a central warehouse. When it arrived we were to call BT to arrange the next visit to fit the part, not pre-arrange to turn up with the part. The part didn't resolve the problem so he ordered a different one to be sent to us and again we had to wait until it was physically here to call him out. In the end it took 3-4 days to fix the system, we got a small amount of 'compensation' from BT but the whole process was torturous. I expect they've done a cost analysis on carrying parts and decided the central warehouse is best for them. Horrendous for their supported customers though.
