I am supposed to be looking at a 5 year plan to upgrade our OPT 81. With this thing being EOL I am wondering what may be a reasonable path for a forklift upgrade? I don't have any experience with other equipment so I am picking some other brains out there for input....ultimately they are not looking at a VOIP solution. (Nuclear plant - security, blah, blah,...) I don't know how much longer I am going to have vendor support for the 81 but I have a complete 81 as a spare! (got it cheap last year) I also have the option to pick up an ASPECT on the cheap. We don't need any call center type switching, just straight up analog/digital support. There isn't very good infrastructure cabling inside the plant which is one hurdle I may have. What say you guys?
