Hi,You need to install the UC


You need to install the UC license for the voice support. When you issue the Show version command on the router, it will show you all the installed and active licenses on your device:

Technology Package License Information for Module:'c2900'

Technology    Technology-package           Technology-package
                        Current       Type                Next reboot  
ipbase        ipbasek9      Permanent         ipbasek9
security      securityk9    Permanent         securityk9
uc               None              None               None
data           None              None                None

In My case I do not have the UC license Activated. You need to first have the license installed in order to activate it.

There are two ways of getting the license. One is by purchasing the license from Cisco and the other is by requesting for a free 60 day trial license. Once you have the license with you.. copy the license file to the flash of the router and then key in the command

2951#license install flash0:FHH1216P07R_20090528163510702.lic

Hi,Hope you used the license


Hope you used the license key that you generated for the device that you have and not the one that I have pasted in the reply. the license will be generated based on your Product ID and the serial number.

So do not use any other license key.... Kindly go through the steps that have been given in the doc to generate the license.

The license that you have installed is the permanent one.

And you should be good to go.....
