[cisco-voip] IPMA vs. Attendant Console

[IT]

Can people please share their experiences with IPMA and Attendant
Console?
I am trying to figure out what the added benefit for each is, so I can
install the correct solution for each "Executive Admin" we have in the
office.
The real problem is that Admin's will answer lines for multiple
executives, and each executive will have multiple admins...
What has everyone else done? 
Also, I can't seem to find any software updates for Attendant Console. I
am running 1.3(1 ES6)
Is this most current?

Thanks,
Avidan
