[cisco-voip] Cisco IT "EMAN"

[Bill Simon]

I found Cisco's case study on their own internal deployment of 
CallManager quite interesting: 
http://www.cisco.com/web/about/ciscoitatwork/downloads/ciscoitatwork/pdf/cisco_ip_telephony.pdf

It mentions an internally-developed suite called "EMAN" used for 
monitoring and managing the voice system and the rest of the network.

More on EMAN:

Can any Cisco people on the list describe a little more about EMAN?

Makes me wonder if we should all be developing our own customized, 
in-house management and monitoring systems.  So far it has been 
discouraging (the price tags, mostly) looking at solutions from 3rd 
parties.  And there doesn't seem to be any indication here that Cisco is 
using any of its own stuff like Operations Manager, Unified Provisioning 
Manager or the like.
