I have a customer that currently deploys Exchange 2003 housing approx. 350 email mailboxes. He looking to integrate a Cisco IPT solution (CUCM 6.1 and Unity 5.0). Before the IPT integration he wants me to install a new Exchange 2007 server. I would like to "size" the new Exchange 2007 server to take into consideration the Unity 5.0 install.
Does Cisco provide any "sizing" tools/documentation/recommendations for an Exchange 2007 server when integrating w/ Unity?
Any information would be greatly appreciated.
It's not really sizing on the Exchange 2007 box that matters. What matters is how much space you are allocating to Voicemails. For instance, I think the ratio is 30 minutes of voicemails is about 15megs of space required. (at G711 codec)
So do the math:
30 minutes of voicemail recordings
15 megs per 30 minutes
350*15 megs = about 5gigs of extra space required.
People can of course more voicemails to "personal folders" and store them like any other email attatchment, etc.
hope this helps
