Hi,
I guess the reason why this query has not been answered is because you have opened this post in security forum.
Coming to your query following are the licenses -
1) CCME Feature License -
For example -
FL-CCME-36 Cisco CallManager Express Feature License For Up To 36 Users
This license decides how many IP Phones you can have on the CCME router.
2) Phone licenses - Its RTU license which gies you the entitlement to use the IP Phone with CCME.
For 7941 IP Phone for example you'll have to order the following -
SW-CCME-UL-7941 License, CCME, Cisco IP Phone 7941
