microsoft lync 2010 Vs Call manager

Hi to everyone,

i am searing since a week for a good reason to convenience our management to
go with call manager instead of Microsoft Solution, but i couldn't the only
thing which i found is the following

1-MS doesn't support special type of video codex
2- MS doesn't support the Forced Authorization Code
3-MS doesn't offer contact center solution, and also webex
4-MS solution is layer 7 application which deals with voice like any other
programs it will not treat it as priority traffic !!!

On the other hand
MS will give us
1- unlimited number of softphones which will reduce the cost of the comparison
a lot
2-MS will support Voice messaging, auto attended feature as well

we are planning to go with 400 users, but till now i cannot convince the
management and convince myself regarding MS product.

If you can help me to judge which product is better and why that will be
great.

Thx,
