This a an excellent router from the Cisco G2 Series and will work great from CCNA, CCNP and especially if you want to explore voice content. This router comes with the Base, Security and UCK9 (Voice) license. These are permanent licenses that come already installed on the device. The 2921 Router is a step up from the 2911 with an additional PVDM slot, and doubles some of the capability of the 2911. See below.
