Purpose The purpose of this document is to explain how license activation works on a Cisco ISR-G2 (19xx/29xx/39xx) router. It will detail how to install the license and verify that it has been actived correctly. How does Licensing for CME/SRST work? The CME/SRST feature is accessible only once the uck9 technology-package license has been accepted and the router has been reloaded. If the uck9 technology-package license is not installed or the router not reloaded, no voice related commands will be accepted by the command line. Once the technology-package license is installed, it gives access to the CME/SRST feature set. To determine the current status of the technology-package license, check the output of the "show version" command. It will provide the state of the technology packages currently active.

INSTALLING THE LICENSE OR LICENSE  KEY  PROVIDED FOR  ANY CISCO  PRODUCT  FEATURE  OR  USING SUCH PRODUCT  FEATURE  CONSTITUTES  YOUR  FULL ACCEPTANCE  OF  THE FOLLOWING TERMS. YOU MUST NOT PROCEED FURTHER IF YOU ARE NOT WILLING TO  BE BOUND BY ALL THE TERMS SET FORTH HEREIN. Use of this product feature requires  an additional license from Cisco, together with an additional  payment.  You may use this product feature on an evaluation basis, without payment to Cisco, for 60 days. Your use of the  product,  including  during the 60 day  evaluation  period,  is subject to the Cisco end user license agreement http://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.html If you use the product feature beyond the 60 day evaluation period, you must submit the appropriate payment to Cisco for the license. After the 60 day  evaluation  period,  your  use of the  product  feature will be governed  solely by the Cisco  end user license agreement (link above), together  with any supplements  relating to such product  feature.  The above  applies  even if the evaluation  license  is  not  automatically terminated  and you do  not receive any notice of the expiration of the evaluation  period.  It is your  responsibility  to  determine when the evaluation  period is complete and you are required to make  payment to Cisco for your use of the product feature beyond the evaluation period. Your  acceptance  of  this agreement  for the software  features on one product  shall be deemed  your  acceptance  with  respect  to all  such software  on all Cisco  products  you purchase  which includes the same software.  (The foregoing  notwithstanding, you must purchase a license for each software  feature you use past the 60 days evaluation  period, so  that  if you enable a software  feature on  1000  devices, you must purchase 1000 licenses for use past  the 60 day evaluation period.)    Activation  of the  software command line interface will be evidence of your acceptance of this agreement. ACCEPT? [yes/no]: yes The above End User License Agreement must be accepted and the router reloaded before the license is actived. Once the router is reloaded, the output of the show version  command will reflect the change in status of the uc technology package.

This indicates that the features associated with the UC technology-package are active but the router is using an evaluation license which will expire. Steps to install the permanent license can be found in the official documentation. Cisco’s Integrated Services Routers Generation Two Licensing and Packaging Once the permanent license is installed, the type will change to RightToUse as depicted in the below output.

The only step needed is to configure the CME/SRST feature and accept the EULA. Viewing the output of show license detail cme-srst indicates that there is no configuration present and the EULA has not been accepted.

It will cover how to activate the CME/SRST feature license. Step 1: Go to global configuration mode. Issue the config t command. Step 2: Issue the telephony-service command. Step 3: Issue the max-dn <dn> and max-ephone <ephone> commands. Once the last command is entered, you'll be prompted to accept the EULA.  Router(config-telephony)#ip source 10.1.1.1 Router(config-telephony)#max-dn 10 Router(config-telephony)#max-ephone 10 PLEASE  READ THE  FOLLOWING TERMS  CAREFULLY.

ACCEPT? [yes/no]: yes Verifying License Status Once the feature has been configured and the EULA accepted, check the status of the license with the show license detail cme-srst command. The output should show the License State as Active, In Use.

This will show the EULA and provide the option to accept it. Note that even after accepting the EULA, the License Type says EvalRightToUse and output shows an Evaluation period. This is because the evaluation is ACTIVE for 60 days. After 60 days i.e. on "Transition date" this will change to RightToUse. ... View more
