Another ShoreTel Replaces Another Old Phone System

I just put in another ShoreTel phone system to replace another old PBX system.  "Another one bites the dust" appears to be the saying.  I took a picture of what Im replacing and Im putting in place a ShoreTel 13 system on a virtual server with one u in rack space of shoregear equipment.  Looks like we are not only getting a better phone system, but also saving a lot of room.
