Yes, STA determined by the PBX error and svmi error logs (and their inability to reproduce the problem in Dallas or Korea) its not a problem with the 7400 PBX, but rather an issue with the SVMI20e card itself. They had me send it in for repair (this would be the second time this card has been in for this same issue).
Its returned from repair a couple days ago. Usually the repair depot does not include what was done to fix the problem, but this time they wrote a 2 word note: "Software problem". They replaced the software on the CF card (instead of the whole card); customer is not happy - they want to keep the loaner CF card which has been rock solid since first week of January and this also means they do not have to re-do their 120+ mailboxes.
What this has done for this customer is primed them for a new phone system - they want new equipment - ready to actually sign a cheque.
Sadly, Samsung has nothing to offer as 'new phones'; customer does not want to spend the money upgrading their network switches or their data cabling/closets. Customer originally bought Falcon iDCS sets, then added the "newer" DS series (my personal opinion is they look like ikea phones design/color wise). So when we talk to them about a new phone system, we get "what? you're selling me the same model phones as I bought 7 years ago? Um no.
Further, I have a number of 50+ user 7000 series systems that are now aging (7200/7400), customer is starting to hint at wanting upgrades. I've talked to them about the new WeVoIP which I personally really like. Mostly they need desk phones, and often the middle exec's do not want to be THAT connected. They love us for the service, but i'm not sure i'll be able to keep them since they don't want the IP sets.
Frankly I can't blame them, they don't want/need the IP phones (some even don't like them - they have had a couple of them to try out as an upgrade option). We'll likely loose them this summer. I know 'the future is IP', but it hasnt happened yet, we still sell A LOT of TDM phone systems. I really believe we're going to loose a number of our customers because of this. Trying really hard to not make this sound like i'm whining. I love the samsung product - great software capabilities. I'm making a big presumption that Samsung only really wants to sell to United Airlines or Hertz rent a car / fortune 500. Not very many of those around - and they will go all IP because they have the money / actual need for it. Less than 10% of my customer base will be into that. I just don't see TDM dying this decade.
