I am looking at Shoretel, Cisco and Altigen to replace our aging phone system. I see there has been some great debate compaing these systems. Is there any specific details that make one stand out over the other? Some one commented that AltiGen was a poor choice based on hardware. I had read a number of positive things about Altigen and the system seemed pretty easy and flexible. It is on a Windows platform which I think is a negative also the Outlook integrations is not as strong as Shoretel. I do not plan to do VoIP but have regular T's for phone traffic so the WAN stuff should not be an issue. Any comments would be appreciated. THank you.
