1) What do you want to do? Do you even know whats available? Did anyone sit down and ask you what your goal was or did you dictate the features you wanted?

2) The Panasonic is more of a key-hybrid. IE it has more key features than pbx. The Aspire has more pbx feature and gets alot bigger.

3) These systems have a life of about 5-7 years. Other systems last much longer and are upgradeable. Also they usually have more features.

I have been on many accounts where I was told what they wanted EXACTLY, they would not listen to what I had to say, then changed their minds AFTER the system was put in wanting XYZ and they only paid for an X, because there is a reason you get what you pay for.
