Our clients have multiple methods of accessing the PSTN and these have very different cost profiles (eg Satellite, GSM, POTS, VSAT). One thing they all have in common is an analogue RJ11 interface. Traditionally we have used Panasonic Hybrid TDM PBXs because these provide quite advanced PBX functionality whilst being able to offer the user of any phone the choice of multiple trunk lines. Our clients have no need for AA and do not have the luxury of a receptionist so we normally configure a hunt group to allow them to answer an incoming call anywhere. They are not sat together in a small office so a key system is not going to be suitable.
So far the various adaptations of CME I have seen attempted for these clients have not worked out well so Panasonic still dominates the market. I last played with UC500 a couple of years ago so am not familiar with recent software improvements. Could you tell me if UC500 is now a viable competitor for Panasonic for my clients by offering the features I have described above?
