-Handle a PRI (hopefully allow forwarding of old PBX DIDs)
-Handle long distance T1 (we would initially segment off some channels from our current PBX)
-Handle WAN Traffic so we could utilize our unused channels for long distance from other locations
-Forwarding of voicemails to email
Nice optional features:
-Web based GUI for voicemail administration
-GUI call manager
Eventually, we would have relay units at the other locations to handle the local calls and call routing and have 1 central PBX at corporate headquarters."
