OK, I'll bite.

Question 1: Are you a Cisco shop now? If not then you should lean towards Shoretel. If you have all Cisco network equipment now and are Cisco trained then lean in that direction.

2: Better system? That is too subjective to the user/installer/sales person to answer really. It depends on the application.

3: Future growth. Shoretel makes it easy to grow to over 20,000 endpoints with just adding Shoregear boxes that can be distributed across the network or local, all with a single system image....because it is one system, not disparate systems networked together.

4: Call center? Would you need a full blown contact center or would Shoretel wrokgroups (for more basic call centers, but still powerful) work? If workgroups works for your application then Shoretel makes a great cost effective solution. Even if you needed to go to ECC for a full blown contact center solution then Shoretel is still cost effective.

5: Remote users? Define your application.

6: Fully redundant: Shoretel is incredibly cost effective when you need redundancy. It can be as redundant as you need.
