Feature Set Tables
Cisco IOS software is packaged in feature sets consisting of software images—depending on the platform. Each feature set contains a specific set of Cisco IOS features.
CautionCisco IOS images with strong encryption (including, but not limited to 168-bit (3DES) data encryption feature sets) are subject to United States government export controls and have limited distribution. Strong encryption images to be installed outside the United States are likely to require an export license. Customer orders may be denied or subject to delay due to United States government regulations. When applicable, purchaser/user must obtain local import and use authorizations for all encryption strengths. Please contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com.

New and Changed Information
The following sections list the new hardware and software features supported by the Cisco 3600 series for Release 12.0(4)XH4.
Settlements for Packet Voice
Internet voice telephony is often used for toll bypass by using an existing data network or the Internet instead of PSTN trunking. Calls of this nature require an originating and terminating gateway to be completed. When the originating and terminating voice gateways are owned by two different carriers, settlement between these carriers is required. The Settlements for Packet Voice project implements a standardized settlement protocol, which can be implemented between different vendors, gateways, and voice settlement servers.
Debit Card for Packet Telephony on Cisco Access Platforms
The Debit Card feature provides the ability to offer calling service with the use of debit accounting to service providers. The Debit Card for Packet Telephony on Cisco Access Platforms is one application supported by the Cisco Interactive Voice Response (IVR) feature. The IVR voice scripts have been modified to use Tool Command Language (TCL) scripts.
TCLWare
The Debit Card for Packet Telephony on Cisco Access Platforms feature requires the use of both Audio Files and TCL Scripts. Unzip and download the files to your TFTP server.
In addition, download the audio files and TCL scripts from the Access Products Service and Support site on CCO at the following "TCLWare" location:
http://www.cisco.com/kobayashi/sw-center/sw-access.shtml
Interactive Voice Response for Cisco Access
Cisco is building voice gateways to connect more traditional telephone networks to voice over IP (VoIP) networks. Customers who are installing VoIP networks often need a mechanism at the gateway to present a customized interface to the caller. The Interactive Voice Response (IVR) feature was first made available to customers with Cisco IOS Release 11.(3)NA2 with the Service Provider VoIP feature set. IVR, with the addition of scripts using Tool Command Language (TCL), is being introduced with Cisco IOS Release 12.0(4)XH. These TCL IVR scripts are the default scripts that must be used with the IVR application in Cisco IOS Release 12.0(4)XH and future releases.
IVR consists of simple voice prompting and digit collection to gather caller information for authenticating the user and identifying the destination. IVR provides the ability to:

H.323 Version 2 Support
H.323 Version 2 Support upgrades Cisco IOS software to comply with the mandatory requirements in the Version 2 specification. This upgrade enhances the existing Voice Over IP GateWay, the Multimedia Conference Manager (GateKeeper and Proxy), and the DTMF digital relay by using H.245.
DTMF is the tone generated on a touch-tone phone when you press keypad digits. The tones are compressed into a single stream at one end of a call and decompressed at the other end by using H.245 messages. However, doing this can lead to distortion, depending upon the CODEC used. Thus, the DTMF-relay is used to configure a method to transport DTMF tones generated after the call is established out-of-band. The three methods are:
•
•
•
H.323 Version 2 defines a lightweight registration procedure that requires full registration for initial registration, but uses an abbreviated renewal procedure to update the gatekeeper and minimize overhead. Lightweight registration requires each endpoint to specify a TimeToLive (TTL) value in its Registration Request (RRQ) message.
The H.323 Version 2 gateway supports the registration of fully-qualified E.164 numbers with the gatekeeper for phones connected directly to the gateway. Tunneling through H.225 User-to-User Information Element (UUIE) facilitates transparent handling of supplementary services between two endpoints through a VoIP network. This eliminates the need to interpret various supplementary signaling messages in the VoIP gateways.
The H.323 Version 2 gatekeeper selects a destination gateway by choosing a gateway from among all gateways registered in a zone by allowing you to assign selection priorities to these gateways based on the dialed prefix. Gateway resource reporting allows the gateway to notify the gatekeeper when H.323 resources are getting low. The gatekeeper uses this information to determine which gateway it will use to complete a call and maintains a separate gateway list ordered by priority for each of its zone-prefixes.
Important Notes
This section contains important information about using your Cisco IOS Release 12.0(4)XH4 software.
Note
Caveat CSCdr91706 and IOS HTTP Vulnerability
A defect in multiple releases of Cisco IOS software will cause a Cisco router or switch to halt and reload if the IOS HTTP service is enabled, browsing to http://router-ip/anytext?/ is attempted, and the enable password is supplied when requested. This defect can be exploited to produce a denial of service (DoS) attack.
The vulnerability, identified as Cisco bug ID CSCdr91706, affects virtually all mainstream Cisco routers and switches running Cisco IOS software releases 12.0 through 12.1, inclusive. This is not the same defect as CSCdr36952.
The vulnerability has been corrected and Cisco is making fixed releases available for free to replace all affected IOS releases. Customers are urged to upgrade to releases that are not vulnerable to this defect as shown in detail below.
This vulnerability can only be exploited if the enable password is known or not set.
You are strongly encouraged to read the complete advisory, which is available at http://www.cisco.com/warp/public/707/ioshttpserverquery-pub.shtml.
Deprecated MIBs
Old Cisco Management Information Bases (MIBs) will be replaced in a future release. OLD-CISCO-* MIBS are currently being migrated into more scalable MIBs—without affecting existing Cisco IOS products or NMS applications. You can update from deprecated MIBs to the replacement MIBs as shown in the following table.
Limitations and Restrictions
The Settlement for Packet Voice feature is offered only in crypto images, so that Cisco can provide export controls.
Before you can download 56-bit or 56i encryption images, the image must first go through the entitlement process. This process makes sure that the image is from a registered DNS address and that the images are not coming from an encryption-restricted country (Iraq, Libya, etc.). You can entitle yourself by filling out the forms located at the following URL:
http://www.cisco.com/kobayashi/library/12.0
Once you are entitled, you can see crypto images in the upgrade planner. You do not have to entitle yourself again, unless you come from a different host. You do not have to entitle yourself for every release. Entitlement is good for all releases.
If there are any problems with your entitlement, you will either be directed to help on DNS registration (if that is your problem), or your case will be escalated to David Moore in ECRA who will review it himself.
Also, all users MUST be entitled before they can receive 56 or 56i images. Never give a 56 or 56i image to a customer if you are uncertain about their entitlement status.
Caveats
Caveats describe unexpected behavior in Cisco IOS software releases. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious.
This section only contains open and resolved caveats for the current Cisco IOS maintenance release.
All caveats in Release 12.0 and Release 12.0T are also in Release 12.0(4)XH4.
For information on caveats in Cisco IOS Release 12.0, see Caveats for Cisco IOS Release 12.0, which lists severity 1 and 2 caveats, and is located on CCO and the Documentation CD-ROM.
For information on caveats in Cisco IOS Release 12.0T, see Caveats for Cisco IOS Release 12.0T on CCO and the Documentation CD-ROM.
Note
Open Caveats—Release 12.0(4)XH4
This section describes possibly unexpected behavior by Release 12.0(4)XH4 and describes only severity 1 and 2 caveats:
Miscellaneous
•
The router configured as the standby gatekeeper fails to complete the call after the primary gatekeeper is shutdown. The h225 channel is terminated with error number 134.
•
H323 traffic is taking a data path to the destination when an ASR path is configured.
Resolved Caveats—Release 12.0(4)XH4
