Feature Support
Cisco IOS software is packaged in feature sets that consist of software images that support specific platforms. The feature sets available for a specific platform depend on which Cisco IOS software images are included in a release. Each feature set contains a specific set of Cisco IOS features.
To improve the usability of the release notes documentation, Cisco IOS Release 12.4(4)XC release notes no longer contains the feature set tables. The feature-to-image mapping that was provided by the feature set tables is available through Cisco Feature Navigator.
Cisco Feature Navigator is a web-based tool that enables you to determine which Cisco IOS software images support a specific set of features and which features are supported in a specific Cisco IOS image. You can search by feature or by feature set (software image). Under the release section, you can compare Cisco IOS software releases side by side to display both the features unique to each software release and the features that the releases have in common.
Cisco Feature Navigator is updated regularly when major Cisco IOS software releases and technology releases occur. For the most current information, go to the Cisco Feature Navigator home page at the following URL:
http://tools.cisco.com/ITDIT/CFN/jsp/index.jsp
For frequently asked questions about Cisco Feature Navigator, see the FAQs at the following URL:

CSCse56501A device running Cisco IOS software that has Internet Protocol version 6 (IPv6) enabled may be subject to a denial of service (DoS) attack. For the device to be affected by this vulnerability the device also has to have certain Internet Protocol version 4 (IPv4) User Datagram Protocol (UDP) services enabled. To exploit this vulnerability an offending IPv6 packet must be targeted to the device. Packets that are routed throughout the router can not trigger this vulnerability. Successful exploitation will prevent the interface from receiving any additional traffic. The only exception is Resource Reservation Protocol (RSVP) service, which if exploited, will cause the device to crash. Only the interface on which the vulnerability was exploited will be affected.
Cisco is providing fixed software to address this issue. There are workarounds available to mitigate the effects of the vulnerability.

Conditions
Workaround
CSCsf98754: Inband DTMF should be squelched for calls from POTS to SkinnySymptom : The following scenario is seen:
PSTN === Analog or T1 CAS FXO === CME ------ VG224 ---- Phone or IVRThe analog ports on the Cisco VG224 are SCCP controlled by Cisco CME.
For a call between PSTN and a Cisco VG224 port (or an IP Phone), the DTMF detection is turned ON on the FXO port. Along with this, the DSP channel associated with the FXO port is programmed to pass through the DTMF tone in the RTP path instead of suppressing it.
The above manifests into a double DTMF digit scenario and is very well pronounced when the Cisco VG224 port is connected to an IVR system looking for digits. For the endpoints controlled by Cisco CME via SCCP, the DTMF relay happens through out of band SCCP messages. Since the original DTMF digit coming from PSTN is not suppressed, we see two digits reaching the IVR system - one from the SCCP message from Cisco CME to the Cisco VG224 port and the second one embedded in the RTP path.
Conditions
Phone----FXS=CME----- IP Phone or VG224Make a call from phone on the left to a CME controlled endpoint. Press a digit button on the left phone and hold it for a long time. The user on the CME controlled endpoint on the right can hear: digit beep, silence and continuous digit beep. If the squelching flag was set on the FXS DSP channel, the user would have heard digit beep, silence and back to voice path.

CSCsc74783Symptom : Intrusion Prevention System (IPS) signatures that require inspection of TCP flows below port 550 may not be triggered on a Cisco IOS IPS device.
Conditions
Workaround
Further Information: On a Cisco IOS router with IPS (Intrusion Prevention System) enabled, all TCP flows should be subject to TCP stateful inspection until the TCP 3-way handshake is complete. This does not work for TCP sessions with a destination port that is less than 550, if it does not match a predefined signature on the router.

Workaround
CSCse15025:Intermittent analog/cas voice port lockup or robotic voiceSymptom : An analog or digital CAS port enters a state in which inbound or outbound calls, or both, may no longer function through the port.
Conditions
When this problem occurs, it impacts multiple ports that share the same signaling DSP. The output of the show voice dsp signaling EXEC command shows which DSP is used by a port for signaling. The symptom may occur more often for ports that use DSP 1 on the PVDM2 module for signaling.
Because this issue impacts the signaling channels, it has been seen that calls either will not connect at all through impacted ports or in some cases when multiple simultaneous calls are present on adjacent voice ports/timeslots, the call may connect momentarily before being disconnected.
If a problem occurs only on a single voice port, there is another problem, not this caveat (CSCse15025). PRI/BRI calls are not affected because PRI/BRI does not utilize the DSP for signaling purposes.
When the symptom occurs with either a VIC2-xFXO or EVM DID/FXS module, enter the terminal monitor command followed by the test voice port port- number si-reg-read 39 1 command for one of the affected ports. The output typically should be a single octet value for register 39. When the symptom occurs, information for Registers 40, 41, and 42 is presented and some of the registers show double- octet information. See the example output (2) below.
When the symptom occurs with FXS or analog E&M modules, enter the terminal monitor command followed by the test voice port port- number codec-debug 10 1 command for one of the affected ports. The output typically should be a single octet value for each register. See the example output (4) below.
Workaround
CSCse47338: H245-signal dtmf relay requires signal update to end digitsSymptom : A third party device sends dtmf-relay using a h.245-signal, which includes duration of the digit. The CME gateway sends the digit to CUE, but the digit is not considered done unless another digit is received. This results in %SIP-3-DIGITEND: Missing digit end event messages sages.
