Feature Licenses for Cisco Unified SIP Proxy Release 8.5
Note In Cisco Unified SIP Proxy Release 8.5:
•Licensing is based on Cisco Software Licensing.
•Support is provided for evaluation licenses. See the "Evaluation Licenses for Cisco Unified SIP Proxy Release 8.5" section.
•To determine the SKU for electronic delivery, add L- before each SKU, for example, the eDelivery SKU for FL-CUSP-2 is L-FL-CUSP-2.
•Feature licenses cannot rehosted.
•Feature licenses with <number>U<number> in the SKU are upgrade licenses.
•The licensed number of requests per second refers to new incoming SIP requests. Requests that belong to an existing dialog, including SIP responses, are not counted.

Table 6 shows the licenses per device for the Cisco Unified SIP Proxy Release 8.5.
If you order the Cisco Unified SIP Proxy Release 8.5 software and licenses when you order the Cisco Unified SIP Proxy hardware modules and routers, the factory installs the software and licenses on the modules for you. No additional key or code is required to enable the licenses. However, if you order spare licenses after the original hardware purchase, you will get a product activation key (PAK) that can be used to generate a license from http://www/cisco.com/go/license.

Open Source Licensing
Some components of the software created for Cisco Unified SIP Proxy Release 8.5 are provided through open source or commercial licensing. These components and the associated copyright statements can be found at:
•Created an intuitive and easy-to-use graphical user interface (GUI) that can be used to configure, manage, monitor, and troubleshoot Cisco Unified SIP Proxy. Complete details about how to use the GUI can be found in the GUI Administration Guide for Cisco Unified SIP Proxy Release 8.5 or in the online help in the application.
•Added support for the Cisco Unified SIP Proxy on the SM-SRE-700-K9 and the SM-SRE-900-K9 SRE modules. These service modules are supported only on the Cisco 2900 Series and Cisco 3900 Series routers. Cisco Unified SIP Proxy Release 8.5 continues to be supported on the NME-CUSP-522-K9 module.
•Included the ability to enable or disable the Lite Mode, which provides the ability to run Cisco Unified SIP Proxy at higher call rates than the licensed call rates by disabling the record-route functionality.
•Added enforced licensing using Cisco Software Licensing (CSL). Beginning with Cisco Unified SIP Proxy Release 8.5, software licenses must be installed and activated prior to use.
•Updated the functionality of route tables. You can now have a route table that consists of both routes loaded from a file and routes configured on the system, you no longer have to keep the route table file in the upload location after you have uploaded the information. For more information, see the route table file CLI command description in the CLI Command Reference for Cisco Unified SIP Proxy Release 8.5.
•Added support for call admission control for server group elements. Call admission control enables the Cisco Unified SIP Proxy to limit the number of calls sent to each server group element.
•Added performance control support to restrict the number of calls per second that the Cisco Unified SIP Proxy can process.
•Added a SIP message log that captures the SIP messages sent and received by Cisco Unified SIP Proxy. The SIP message log has call search capabilities and can be accessed through the GUI.
•Added a failed call log that can capture the call record details for calls that do not terminate normally. The f ailed call log has call search capabilities and can be accessed through the GUI.
•Added support for Simple Network Management Protocol (SNMP). SNMP can be configured through the GUI.
Cisco Unified SIP Proxy Release 8.5.3 is a maintenance release. There are no new features.
For information about installing Cisco Unified SIP Proxy Release 8.5, see the Installation Guide for Cisco Unified SIP Proxy Release 8.5.
Limitations and Restrictions
The following are the limitations in Cisco Unified SIP Proxy Release 8.5.1:
•CSCtj33506: Starting with Release 8.5, the route table configuration is not part of the standard Cisco Unified SIP Proxy configuration. Therefore, if you roll back the system configuration, the route table configuration is not affected. The route table configuration will continue to be the most recent configuration and not the configuration that was in place during the last commit. The workaround for this limitation is to use the backup and restore feature instead of rolling back the configuration.
•CSCtj23166: Monitor charts do not work with Internet Explorer for HTTPS connections. This issue is a browser compatibility problem with secure connections (HTTPS) and the Adobe Flash Player used for the monitor charts. It only occurs for Internet Explorer versions 7 and 8 using HTTPS connections. The system displays the charts normally with Firefox (for both secure and non-secure connections) and for Internet Explorer when using non-secure connections.
•CSCto14786: Sub-interface creation failed on CUSP SRE700/900 modules.
There are no limitations in Cisco Unified SIP Proxy Release 8.5.2.
There are no limitations in Cisco Unified SIP Proxy Release 8.5.3.
For call admission control to work correctly, record route should be enabled on Cisco Unified SIP Proxy. If the record route is not enabled, call admission control will not work reliably.
