Can anyone tell me actual differences between the UC520 and UC560 with regards to memory and processor/performance. I have a customer who is running a UC520 with multiple services and high bandwidth internet. The only have 16 phones but they run the processor between 60 an 100% quite frequently. I'm trying to find some specs as to how the UC560 might improve performance and run at a lower CPU utilization. I've looked at the data sheets, but they are pretty vague with redards to the details. The 560 will support up to 104 phones, but it doesn't go into more detail than that.
Thanks In Advance- David
