IOS 15 is a single software package for the hardware platform that your are using. Now that flash is cheap and large, there doesn’t need to be a different IOS image for the different versions with the advanced features. So you get one software image that has all the features for that platform.

Prior to IOS 15 , we used to have 8 IOS images, all routers came with IPBase image and according to your needs you can choose what IOS image to install on your router as each image had different features than others as illustrated below.

• Introducing the New Cisco Catalyst 2960-L LAN Lite Series Switches. LAN Base License: Cisco Catalyst 2960, 2960-S, 3560-X, and 3750-X Series Switches. LAN Base is a powerful license for layer 2 access switches. Its broad range of access features covers all LAN Lite capabilities plus more robust features such as VTPv3 and FlexLinks.
• Buy a Cisco IOS Enterprise Services SSH - (v. 15.1(1)SG) - license or other Network Management at CDW.com.
• IOS 15 does not apply to all switches and routers. See this guide below that provides a good explanation. For example 3750X switches can run IOS 15 but the 4500 run Cisco IOS 3.5E. White Paper: Cisco IOS and NX-OS Software Reference Guide - Cisco Systems. What VOIP feature in particular did you want to run on your switch and what model is it?

Solved: I've got a WS-C3750G-24TS running IOS 12.2. When going to the website to try and download IOS 15, the latest version of IOS that shows up for this is still IOS 12 with just a few more updates, but IOS 15 doesn't show.

The universal IOS image is loaded by Cisco manufacturing on all shipped routers. An IOS universal image contains all IOS features. Feature sets in the universal image are unlocked using licensing keys, i.e. the level of IOS functionality available is determined by the license applied to the device. A new license only needs to be applied to upgrade IOS functionality on the router. Maintenance upgrades of IOS, i.e. moving from one IOS universal image version to another, does not require a new licensing key. Reboot of a router is also licensing transparent.

Each device ships with universal image, IPBase, DATA, Unified Communications (UC) and Security (SEC) technology packages are enabled in the universal image via Cisco Software Activation licensing keys.

The details of each technology package license can be found in the table below. The new ISR routers also offer a Software Activation feature license and right to use feature licenses. The Software Activation feature licenses use the same Software Activation model as the technology package licenses, while right to use feature licenses are not enforced. Feature licenses work in conjunction with technology package licenses, e.g. the SSLVPN feature license requires a SEC technology package license.

How to get License from Cisco and how to install it in my Router ?
