Ever wondered how to configure a FXS card on an ISR router to register to CUCM using SCCP protocol?  It’s actually easier than you might think.  The benefits of this type of configuration over a traditional H.323 configuration using dial-peers is that you the customer can manage the device and the extensions assigned to a device without needing to know any IOS commands and change any dial-peers or router configurations, it’s all done through the CUCM interface.
