This document describes the new features, system requirements, and caveats for Cisco Unified SIP Proxy 1.1.3. Use this document in conjunction with the documents listed in the "Related Documentation" section.
Cisco Unified SIP Proxy is designed to help connect and manage SIP networks. The Cisco Unified SIP Proxy module is designed to be an integrated solution in Cisco 3800 Series Integrated Services Routers (Cisco ISRs). The module provides multiple features including SIP trunk aggregation, name resolution, routing, scalability, and high availability.
The Cisco Unified SIP Proxy module runs on the NME-522 module. The part number of the Cisco Unified SIP Proxy module is NME-CUSP-522-K9. The module has 2 GB of RAM and 160 GB HDD. This module installs only on the Cisco 3825 or 3845 ISRs.
The Cisco Unified SIP Proxy module requires Cisco IOS Release 12.4(22)T or a later release on the Cisco ISR with k9 feature set.

New Features and Enhancements
This section contains new features or enhancements added in this release.
•Cisco Unified SIP Proxy uses Netconf to perform IOS configuration validation at startup. Netconf over SSH is the only supported mechanism. Support for Netconf over BEEP has been removed. See configuration examples and tech notes for details at http://cisco.com/en/US/docs/voice_ip_comm/cusp/rel1_1_3/configuration/guide/cuspgd113.html
•New configuration commands have been added to configure IP routes to facilitate support for multiple network interfaces. See the command reference for details at http://cisco.com/en/US/docs/voice_ip_comm/cusp/rel1_1_3/command/reference/cuspcmdref_book.html
The software is already loaded at the factory, and you can install it using the command:
software install clean url ftp://x.x.x/cusp-k9.nme.x.x.pkg
There are three software files, all of which you should save to the FTP directory. You need to load the .pkg file, the other files are downloaded automatically. See Table 1..

Limitations and Restrictions
Changing Licenses Requires Backing Up Your Configuration
Whenever you change the license for Cisco Unified SIP Proxy Release 1.1.3, the system restores the software to its factory default settings, thereby deleting your system's configuration data.
Therefore, if you need to change the license, you must first back up your configuration. After you change the license, you must restore the configuration. Otherwise, you will lose all of your system's configuration data.
Caution You must back up your system's configuration data before changing the license or you will lose all of your system's configuration data.

Voice and Router Coresidency Restrictions
Voice and router functions may co-reside in the same router with Cisco Unified SIP Proxy with two exceptions:
•Cisco Unified SIP Proxy may not co-reside in the same router when Cisco Unified Communications Manager Express (Cisco Unified CME) or Cisco Unified Survivable Remote Site Telephony (Cisco Unified SRST) are configured for SCCP phones.
•Cisco Unified SIP Proxy may not co-reside in the same router with time division multiplex (TDM) gateways or configuration of H.323 dial peers (including Cisco Unified Border Element).
Cisco Unified CME, Cisco Unified SRST, and Cisco Unified Border Element configured for SIP may co-reside in the same router.
These caveats describe unexpected behavior in Cisco Unified SIP Proxy software releases. Severity 1 caveats are the most serious caveats. Severity 2 caveats are less serious. Severity 3 caveats are moderate caveats, and only selected severity 3 caveats are included in the caveats document.
Note If you have an account on Cisco.com, you can use Bug Toolkit to find caveats of any severity. The Bug Toolkit is at: http://www.cisco.com/pcgi-bin/Support/Bugtool/launch_bugtool.pl
