I've been installing 3300's for a few years and have really got to like them, but the reseller I work for has just started to sell IP Office, I installed my first one today and I can safely say what a terrible system!! I absolutely hate it so far... External call diverts are messy, the phones are ugly with tiny screens, the programming is far too complex for even the most basic features. I really hope we drop it after all the negative feedback and stick with Mitel.....
