[c-nsp] MCS7816 Communication Manager

[uugnaa]

Hello all,

I need your support on this if you may came across it.

Company is planing to deploy IP telephony in the network covering 2 remote sites and head quarter.

here is my plan:

85pcs x CP-3911 (Cisco SIP Phone 3911)
1pcs x MCS7816H3-K9-CMB1 (Unified CM 6.0 7816-H3 Appliance, 0 Seats)
2pcs x LIC-CM-DL-100=
1pcs x LIC-CM6.0-7816= (License Unified CM 6.0 7816 Appliance, 500 seats)

My question is this: 

1. What is the DLU for CP-3911 (Cisco SIP Phone 3911) device?  Based on that I can calculate number of LIC-CM-DL-100= license

2. What is LIC-CM6.0-7816=(License Unified CM 6.0 7816 Appliance, 500 seats) license, is it the one for CM application software license. Because I got this line from the Communication Manager v6.0 documentation. Application and phone software licenses are enforced. 

3. Is there any other LIC-CM6.0-7816= license which has few seats, maybe around 100. By the way, what is a seat here. Seat, does that mean the total number that Comunication manager can manage upto?

4. If I go for Unified CM v7.1 then what is the part number for that with MCS appliance?

thank you in advance.
