New Software Features in Release 12.4(4)XC
The following new software feature is supported by the Cisco AS5350XM and Cisco AS5400XM universal gateways for Cisco IOS Release 12.4(4)XC:
AMR-NB Codec
Adaptive MultiRate-Narrow Band (AMR-NB) codec is a highly complex multimode codec that supports eight narrow-band speech encoding modes with bit rates between 4.75 and 12.2 kbps. AMR-NB is designed to preserve high speech quality under a wide-range of transmission conditions. Unlike other codecs, AMR-NB readily adapts to different bit rates based on channel conditions during a call.
The AMR-NB codec was originally developed and standardized by the European Telecommunications Standards Institute (ETSI) for Gropue Speciale Mobile (GSM) cellular systems and chosen by the Third Generation Partnership Project (3GPP) as the mandatory codec for third generation (3G) cellular systems.
How the AMR-NB Codec Works
The multirate encoding (or multimode) capability of AMR-NB is designed for preserving high speech quality under a wide range of transmission conditions. Unlike other codecs, the AMR-NB codec can adapt to different bit rates (see Table 6) based on channel conditions during the call.

1 Used for Silence Indication Detection(SID) frames.
To perform mode adaptation, the decoder (speech receiver) sends a signal to the encoder (speech sender) to indicate which new mode it prefers. This mode-change signal is called codec mode request (CMR). Because speech is sent in both directions between the two ends in most sessions, the mode requests from the decoder at one end to the encoder at the other end are sent in a piggyback form over the speech frames in the reverse direction; there is no out-of-band signaling needed for sending CMRs. The Cisco AS5350XM and Cisco AS5400XM cannot initiate CMRs, but received CMRs can be processed. For more information about AMR-NB codecs, see RFC 3267.
For more information on this feature, see the following URL:
http://www.cisco.com/en/US/docs/ios/12_4t/12_4t15/it_amrnb.html
H.323 VoIP Call Preservation Enhancements for WAN Link Failures
H.323 VoIP call preservation enhancements for WAN link failures sustain connectivity for H.323 topologies where signaling is handled by an entity that is different from the other endpoint, such as a gatekeeper that provides routed signaling or a call agent, such as the Cisco BTS 10200 Softswitch, Cisco PGW 2200, or Cisco Unified CallManager, that brokers signaling between the two connected parties.
Call preservation is useful when a gateway and the other endpoint (typically a Cisco Unified IP phone) are collocated at the same site and the call agent is remote and therefore more likely to experience connectivity failures.
Configuration information for the H.323 VoIP Call Preservation Enhancements for WAN Link Failures feature is included in the "Configuring H.323 Gateways" chapter in the Cisco IOS H.323 Configuration Guide, Release 12.4T at the following URL:
http://www.cisco.com/univercd/cc/td/doc/product/voice/srst/srst40/srst40ad/srs_call.htm#wp1014888
Software Features Ported from Other Platforms in Release 12.4(4)XC
The following features have been previously released on other Cisco access servers and high availability platforms. Therefore the individual platform name may not be referenced for the universal gateways. Other differences may exist for the various platforms that are documented.
Note
Modem Relay
Modem relay demodulates a modem signal at one voice gateway and passes it as packet data to another voice gateway where the signal is remodulated and sent to a receiving modem. On detection of the modem answer tone, the gateways switch into modem passthrough mode and then, if the call menu (CM) signal is detected, the two gateways switch into modem relay mode.
For more information about this feature, see the following URL:
http://www.cisco.com/en/US/docs/ios/12_4t/12_4t4/mdmrly.html
Text over IP
Cisco Text Relay implements a mechanism for transporting Text Telephone (TTY) signals over Voice over IP (VoIP) calls in a highly reliable way. Cisco Text Relay transports both TTY text characters and voice over the same channel, supporting both Voice Carry Over (VCC) and Hearing Carry Over (HCO).
Cisco Text Relay is gateway controlled, enabling it to work independently from the call agent. It can be configured on supported gateways for the SIP, H.323, and MGCP.
Cisco Fax Relay
Cisco fax relay is the default mode for passing faxes through a VoIP network, and Cisco fax relay is the default fax relay type on Cisco voice gateways. Cisco fax relay uses Real-Time Transport Protocol (RTP) to transport the fax data.
For more information about this feature, see the following URL:
Warm Reload
The warm reload feature allows users to reload without reading images from storage. That is, the Cisco IOS image reboots without ROM monitor mode (ROMMON) intervention by restoring the read-write data from a previously saved copy in the RAM and by starting execution without either copying the image from flash to RAM or self-decompression of the image. Thus, the overall availability of your system improves because the time to reboot is significantly reduced.
For more information about this feature, see the following URL:
http://www.cisco.com/en/US/docs/ios/fundamentals/configuration/guide/warm_reload_ps6441_TSD_Products_Configuration_Guide_Chapter.htmll
Warm Upgrade
The warm upgrade feature provides the capability for a Cisco IOS image to read and decompress another Cisco IOS image and then transfer control to this new image. This functionality reduces the downtime of a device during planned Cisco IOS software upgrades or downgrades.
For more information about this feature, see the following URL:
SRTP with H.323
Secure Real-Time Transport (SRTP) mode provides secure Voice over IP (VoIP) calls by addressing security requirements for privacy, integrity, and confidentiality of voice conversations. IPsec, a standards-based set of security protocols and algorithms, ensures that signaling information that is sent between the gateway and Cisco Unified CallManager are encrypted. Media encryption using standards-based SRTP ensures that media streams between supported devices are secure.
For more information about this feature, see the following URL:
http://www.cisco.com/en/US/docs/voice_ip_comm/pgw/9/feature/module/9.8_1_/SRTP.html
DSP Voice Quality Statistics
The Cisco AS5350XM and Cisco AS5400XM universal gateways support the Digital Signal Processor (DSP) voice quality statistics in Media Gateway Control Protocol (MGCP) calls using Delete Connection (DLCX) messages.
For more information about this feature, see the following URL: http://www.cisco.com/en/US/docs/ios/12_3t/12_3t7/feature/guide/gtdspsts.html
Fax-Relay Support for SG3 Fax Machines
This feature allows Super Group 3 (SG3) fax machines to interoperate over T.38 fax-relay or Cisco fax-relay networks. The capability to interoperate over fax-relay networks is achieved by enabling SG3 fax machines to negotiate down to G3 speeds by suppressing the SG3 V.8 fax call menu (CM) signal. The suppression of the SG3 V.8 fax CM signal (or message) is also known as SG3 spoofing.

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.

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.

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.
