what's difference between the two part number? looks the first one is bundle to hardware and the 2nd for additional.
LIC-CM5.1-7815=(License CallMgr 5.1 7815 Appliance, 500 seats)
LIC-CM-DL-500=(CallManager Device License - 500 units)
Thanks in advance,
As you may know already, 7815s can only be run in pub/sub model (just 2 servers) and you can only home upto 500 devices per server. If you need more than 500, then you will need to go to a 7825 which can home up to 1000 devices per server. The seat quantity mentioned here is the server capacity limit.
This part number LIC-CM5.1-7815 does not include LIC-CM-DL-500. You have to order that separate.
The 500 seats in the LIC-CM5.1-7815 part number and the 500 DLUs are not equivalent. A seat could be single phone, a gateway, a cti port, analog port etc. Each phone may be equivalent to X number of DLUs depending on the type of phone.
To summarize DLU is a measure for licensing.
Seat is a measure for server capacity.
Use this tool to size the server appropriately.
