Introduction

The Cisco IAD2430 is the next generation integrated voice and data services platform for Service Providers, building on the industry leading Cisco IAD2420 series IAD. The Cisco IAD2430 series offers a major leap forward in price performance and enhanced software functionality such as MGCP SRST used to accelerate the migration from time division multiplexing (TDM) to VoIP cost efficiently. The Cisco IAD2430 series harnesses the maturity of the Cisco IAD2420 series software and enhances functionality by providing more capabilities such as denser interfaces (up to 24 FXS and up to 2 voice or 2 data T1s), encryption, and DC power back up while maintaining it's 1RU form factor for space saving Service Provider Managed Services deployment.

For information on new features and Cisco IOS commands supported by Cisco IOS Release 12.4(11)XW, see the "New and Changed Information" section.

Synched to technology version 12.4(11)T
Upgrading to a New Software Release

For general information about upgrading to a new software release, see the Software Installation and Upgrade Procedures located at http://www.cisco.com/warp/public/130/upgrade_index.shtml.

Feature Set Tables

The 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. Cisco IOS Release 12.4(11)XW supports the same feature sets as Releases 12.4 and 12.4(11)T, but Cisco IOS Release 12.4(11)XW includes new features supported by the Cisco 2430 IAD.

Caution The Cisco 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 will likely require an export license. Customer orders can be denied or subject to delay as a result of United States government regulations. When applicable, the purchaser/user must obtain local import and use authorizations for all encryption strengths. Contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com.

Table 2 lists the feature and feature sets supported in the Cisco IOS Cisco IOS Release 12.4(11)XW releases.

The tables use the following conventions:

•In: The number in the `In' column indicates the Cisco IOS release in which the feature was introduced. For example, "12.4(11)XW" indicates that the feature was introduced in 12.4(11)XW. If a cell in this column is empty, the feature was included in a previous release or in the initial base release.

•Yes: The feature is supported in the software image.

•No: The feature is not supported in the software image.

Note These feature set tables contain only a selected list of features, which are cumulative for Release 12.4(11)nn early deployment releases only (nn identifies each early deployment release). The tables do not list all features in each image: additional features are listed in Cross-Platform Release Notes for Cisco IOS Release 12.4(11)T and Release 12.4(11)T Cisco IOS documentation.

Resolved Caveats - Cisco Release 12.4(11)XW6
CSCsk61275 no ring on 7941 phone while hunting second overlay number
Symptom    The Cisco Unified IP Phone 7941 does not ring while hunting the second overlay number in Call Forward No Answer (CFNA) configuration.
Conditions   Overlay button is configured on Cisco 7941, and CFNA is configured from the first number to the second number.

Workaround   Use Cisco IOS Release 12.4(11)XJ3 or Cisco IOS Release 12.4(11)T3.
CSCsk09132 Hotice router crashed with debug parser before-after and session-server
Symptom    The router crashes when the maximum permissible number of session-servers are configured for a voice register dn with the command 'session-server 1 2 3 4 5 6 7 8'.
Conditions   A voice register dn should be configured.

Workaround   This symptom can be worked around if one less than the number of maximum session-servers are configured. 'session-server 1 2 3 4 5 6 7 ' should solve this problem if it occurs.
CSCsj81015 IPIP Gateway crash ccsip_bridge
Symptom    Cisco Multiservice IP-to-IP Gateway (IPIPGW) crashes during a stress scenario.
Conditions   This symptom occurs in a stress scenario with 100 SIP-H323 calls + 150 SIP-H323 DTMF interworking (rtp-nte to h245-alpha) calls.

Workaround   There is no workaround.
CSCsk42299 IPIPGW h323 no H.245 TCS with FS-SS interwork call to CCM
Symptom    Cisco IPIPGW does not establish TCP connection for H.245 on the TCP port suggested by Cisco Unified CallManager (CCM).
Conditions   The IPIPGW is configured for FS-to-SS interworking. In CCM, the "Wait for Far-End H.245 Terminal Capability Set" option is unchecked.

Workaround   There is no workaround.
CSCsj27183 Transcoding: Call fails for H323--SIP Fast start call
Symptom    H323-->SIP interworking fails for a Fast start call when transcoding is enabled on an IPIPGW. Transcoding is done between G711ulaw and G729r8 codecs.
Conditions   This failure is seen for H323--SIP--SIP--SIP and H323--SIP--SIP--H323 call flows when transcoding is enabled on IPIPGW1. It is also seen on H323--H323--H323--SIP call flow for transcoding on IPIPGW2. This is seen only with a Fast Start call (both with H245 Tunnel enabled and disabled), and the call passes with a slow start call.

Workaround   There is no workaround.
CSCsl53327 max-ephones and max-dn show wrong range on UC520-48U-SKU.
Symptom    max-ephones and max-dn show wrong range on UC520-48U-SKU
Conditions   This symptom occurs only if the FLU variable is changed.

Workaround   Do not change the FLU variable.
CSCsl79588 Router crashes after changing the MOH
Symptom    Router running Cisco IOS may crash with a bus error.
Conditions   The router must be configured to stream MOH (Music-on-Hold) from a .wav file with a header longer than 256 bytes.

Workaround   Do not use ".wav" files for Music-on-Hold. Use only ".au" files.
CSCsm20994 kron job daily reoccurrences fail after new year
Symptom    kron occurrences are not rescheduled properly when the clock is set near the end of a calendar year.
Conditions   A kron occurrence is scheduled daily or hourly. The clock is reset near the end of the year such that the next occurrence of the kron policy would happen in the next year.

Workaround   After clock reset, remove/restore kron occurrences to cause them to be scheduled properly.

Open Caveats - Cisco Release 12.4(11)XW5

There are no open caveats in this release.

Resolved Caveats - Cisco Release 12.4(11)XW5
CSCsk45804 CME speeddials fails after attempting to invalid number
Symptom    Pressing a speeddial button on CME does nothing.
Conditions   Previously, a speeddial was used to target an unavailable/non-existent number.

Workaround   Connect a normal call on the problematic phone.
CSCsk65748 If POE 48V fails to come up, we need to retry 3 timesCSCsk60054 Configuration buffer full. Cannot display show run
Symptom    When certain configuration changes, the running configuration might not be able to be displayed and the following error message might appear:
% Configuration buffer full, can't add command: !
%Aborting Save. Compress the config, Save it to flash or Free up space on device
Conditions   The issue is seen either using or not using service compress-config on a Cisco IOS Router running CallManager Express (CME) when configuring more than 22 voice user-profiles.

Workaround   There is no workaround.
CSCsk31644 Spurious Access at cmm_crs_proc_tr_call_consult_resp
Symptom    Spurious memory access is seen while executing call forward scenarios.
Conditions   This is seen on c3845 while executing CME and UCCX related test scenarios.

Workaround   There is no workaround.
CSCsk55078 CME 4.2 Diversion Header issue in chained supplementary serviceCSCsk22265 CME: 7935 and 7936 Corporate Directory Lookup fails in CME 4.1 and 4.2
Symptom    When attempting to use the Corporate Directory Lookup feature on a Cisco 7935 or 7936 Conference IP Phone, an attempt to search for matching records using a First Name or Last Name query results in the message "Server not found" being returned.
Conditions   This behavior is observed when the Cisco 7935 and 7936 Conference IP Phones are registered to a Cisco Unified Call Manager Express (CUCME) Voice Router installed with CUCME version 4.1 or newer (IOS 12.4(15)T train and newer, or 12.4(11)XJ and newer). The 7935 and 7936 IP Phones can be installed either with the approved SCCP Firmware Version 7.x or 8.x phone loads.

Workaround   (1) This problem is not observed in CUCME 3.3 (IOS 12.4 mainline) up to 4.0(2) (IOS 12.4(11)T3). If CUCME 4.1 features are not required use these older versions of CUCME. (2) Use a non-79x5 IP Phone registered to the same CUCME Voice Router to perform the Local Directory Search.
CSCsk50911 Need to update the max-ephones range for various platformsCSCsk25651 ephone-dn removal does not clean up mwi state
Symptom    With Cisco Unity Express (CUE) integrated to Cisco Unified Communication Manager (CUCM) / CallManager utilizing SRST functionality, when the IP phones are registered to the SRST router, the MWI states may be incorrect.
Conditions   When a phone registers to an SRST router, each directory number (DN) gets a particular ephone-dn number that will have a particular MWI state. If the phone unregisters from the SRST router and later re-registers to the router (possibly due to an intermittent connectivity to the CUCM), the ephone-dn number may be different since the ephone-dn numbers are assigned sequentially in a first-come-first-served fashion. The MWI state, however, is remembered from the previous registration that used the ephone-dn number so the MWI status could be incorrect.

Workaround   There is no workaround.
CSCsj53899 Remove xlate profile from voice register dn removes from dial-peer
Symptom    Removing voice xlate profile from a voice register dn results in the same xlate profile being removed from a dial-peer.
Conditions   Have the same xlate profile name under a voice register dn and dial-peer and using IOS 12.4(11)XW - XW2.

Workaround   There is no workaround.
CSCsj93762 Resume fails after HOLD for SIP phones regist with voice-class codecCSCsj81363 FRU incorrect and Carrier Set empty on wireless B sku platforms
Symptom    Under the show controller output for the Dot11 interface, the carrier set field is empty. This should say Americas. This does not affect functionality, all of the correct channels are present. Under the show diag output, the FRU says CISCO1811W-AG-A/K9 instead of CISCO1811W-AG-B/K9. This is just the labeling and does not affect functionality.
Conditions   This is seen with the B models of the 1800 wireless routers running 12.4(11)XW1.

Workaround   There is no workaround. This issue does not affect functionality.
CSCsk42889 SIP call xfer to voicemail fails with DNS Query failed error
Symptom    SIP trunk----CME/CUE AA---xfer extension---CFNA---CUE voicemail. Call transfers from AA to extension, CFNA back to CUE voicemail drop.
Conditions   CME running 12.4(11)XW3.

Workaround   There is no workaround.
CSCsk58359 Update max sip phone range for various platformCSCse14595 call may be connected while being cfna to an PSTN call
Symptom    CME allows call connect after CFNA timer expire. On the 3745 with IOS 12.4(5)a customer can pick up the phone and get connected to the calling party after the CFNA timer expire.
Conditions   When this problem is seen then there is a delay between Call-proc and Alerting messages from ISDN side.

Workaround   Use the longer CFNA timer or use the "application default.c.old".
CSCsk35315 CME: calledName= displayed garbled characters
Symptom    Display on Cisco IP Phone contains corrupted characters when placing outbound PSTN call on an ISDN circuit.
Conditions   A Cisco IP Phone placing an outbound ISDN call through a Cisco IOS gateway configured for Cisco Unified Communication Manager Express may experience at times the name displayed on the screen with unrecognizable characters once the call connects.

This can occur if there is an ISDN Facility message received after the call connects that does not contain display name information; for example an inbound facility message for Advice of Charge (AOC) may trigger this problem.

These messages can be seen on the gateway through the use of debug isdn q931. Caution should be taken when enabling any debugs on a production router/gateway as it can impact performance. Make sure as a minimum to disable console logging on the IOS device before enabling any debug. This issue does not have an impact to the operation or performance of the gateway nor phone.

Workaround   Contact the ISDN service provider to determine if the facility messages causing this problem can be disabled.
CSCsk16153 Modem won't be disconnected on exit
Symptom    Modem connection is still active on exit.
Conditions   After "exit" from modem session.

Workaround   There is no workaround.
CSCsk73035 dtmf stop working if using connection plar opx immediate on fxo port
Symptom    dtmf stop working if using connection plar opx immediate on fxo port.
Conditions   Cu is running 124-11.XW on uc520. the dtmf does not work in the following call flow:

pstn--fxo---gw--sip--cue AA

If removing "immediate" from the following config,
the dtmf works.

voice-port 0/1/0
connection plar opx immediate 111
caller-id enable
Workaround   Don't use "immediate" option for the "connection plar opx".
CSCsk46424 Authentication fails on main dot11 interface when xconnect configuredCSCsk52683 System crashed when wireless client is trying to associate with AP
Symptom    System crashes when there are clients trying to associate with AP.
Conditions   When AAA authentication fails with mis-configuration in the system or the wireless client's password is given wrong to try to associate.

Workaround   Make sure the AAA configuration is setup correctly and the client password is configured correctly.
CSCsk17498 Per Port Storm-Control is brokenCSCsj88854 Router crashes when a call is made from Remote Phone registered to CUCME
Symptom    A call made over a SIP trunk from a remote phone registered to Cisco Unified Call Manager Express 4.1 to a phone registered to a SIP proxy server results in router crash due to memory overrun.
Conditions   Phone call has to be from remote phone. MLPPP should be configured as the WAN link. SIP trunk also traverses the same WAN link.

Workaround   Remove the MLPPP.
CSCsj02456 HTTP PUT operation using copy command failed
Symptom    HTTP PUT operation using copy command failed.
Conditions   Failure is seen with HTTP PUT operation using copy command.

Workaround   There is no workaround.
CSCsk83795 call may be disconnected when resetting other ephone

CSCsj14565 ACL = deny; sa request ignored when crypto local-address is dynamic
Symptom    After a reboot of the router, or sometimes during normal operation, an IPsec tunnel fails to initiate. When debug crypto ipsec is enabled, the following error can be seen in the debug output: IPSEC(sa_initiate): ACL = deny; sa request ignored.
Conditions   The router is running 12.4(12) or later, and a crypto map name local-address interface statement is present in the configuration, where interface is the name of an interface that has a dynamic IP address configured (e.g. ip address negotiated or ip address dhcp)

For example:
crypto map mycryptomap local-address Dialer0
interface Dialer0
ip address negotiated
Workaround   A short term workaround consists of removing the access-list used in the crypto map, and then adding it again. This will bring up the tunnel as soon as there is an interesting traffic, but the problem may occur again later. Remove the crypto map name local-address interface statement, if possible. Downgrade to a release earlier then 12.4(12).
CSCsk74181 SIP DO-DO - Basic Fax call fails
Symptom    Fax call fails for a SIP DO-DO call.
Conditions   When the CUBE receives a ReINVITE with fax params, it does not forward the same. Instead it sends a BYE and the call gets disconnected.

Workaround   There is no workaround.
CSCsl04993 uc520 devices does not get reload via SNMP
Symptom    Cisco Unified Communications Series Integrated Services routers are not reloaded through SNMP.
Conditions   Cisco Unified Communications Series Integrated Services routers (ISRs) are not reloaded using SNMP when you restore the device configuration. Cisco Monitor Manager sends a device-reload request to the device after configuration file is restored; however, Cisco Unified Communications 500 Series ISRs do not accept this request through SNMP.

Workaround   To work around this problem, reload the device manually after restoring the configuration file.
CSCsj56438 Crafted EAP Response Identity packet may cause device to reload

CSCsj38652 Freddo DTMF/cptone issues for Taiwan, Hong Kong, Singapore Compliance
Symptom    DTMF levels are 0.3-0.5 dB below minimum limits for DTMF high/low tone signal power for Taiwan, Hong Kong and Singapore.
Conditions   This causes under normal conditions.

Workaround   Setting the cptone on the voice port to Singapore cures the problem.
CSCsk83813 sip call will pick up the wrong codec type from voice class codec
Symptom    When a SIP call is established, the Cisco IOS correctly uses the "codec preference 2" setting (G.711ulaw) that is configured in the voice class codec configuration. When this problem occurs, the tone remote control functionality does not work and voice becomes distorted due to the codec mismatch.
Conditions   A SIP call consistently uses the incorrect codec type from the "voice class codec" configuration. It should use the value that is configured for "codec preference 1," instead it uses the value that is configured for the "codec preference 2" setting. This issue occurs when the following configuration is used:

voice class codec 1
codec preference 1 g729r8
codec preference 2 g711ulaw

CSCsk42180 Few Objects of CISCO-LICENSE-MGMT-MIB giving wrong values during SNMP waCSCsj94818 C877: ADSL2+ AnnexM: PVC goes to INAC after QoS is applied
Symptom    On C877 device for VC which is configured with vbr-nrt and PCR rate higher that VC bandwidth, when changes are introduced (e.g. QoS applied), VC goes in INAC status due to the fact that PCR is higher than physical bandwidth.
Conditions   Problem is seen on C877 device with ADSL2+ and with SW releases 12.4(11)XJ3 and 12.4(15)T1.

Workaround   Resetting VC resolve issue.
CSCsk06443 SIP TGW sends 183 response even though no response from ISDN
Symptom    IOS Gateway is sending 183 Response upon receiving retransmission of Invite Request.
Conditions   IOS GW has sent 100 trying response to original Invite Request and the call is in progress on other leg. Other leg could be either PSTN OR IP.

Workaround   There is no workaround.
CSCsk36600 Router crashes when ExtACL has mixed of tcp host and tcp net with QoS
Symptom    Router might crash when Extended ACL is applied with mixed of tcp permit statements with host and networks and this acl is applied in the class-map.
Conditions   The crash is seen when QOS with this Extended ACL is configured first and ACL statements are defined later.

Workaround   Configure permitted host statements successively and do the same for permitted networks. Configure ACL statements first and attach this ACL to class-map later.
CSCsj80906 Router crashes on changing ACL linked to service policy
Symptom    A Cisco router may crash due to a bus error.
Conditions   This has been experienced on multiple Cisco router platforms running IOS release 12.4(15)T1. The crash can occur if an access-list linked to a service-policy is removed, or if a service-policy is removed on an interface.

Workaround   There is no workaround.
CSCsl17037 CME: Local Directory Issue
Symptom    Directory numbers that are configured in local directory of CME are not being shown in received calls directory. The number and name shows while call in ringing state but is not showing during connected state.
Conditions   This is seen in Inbound call.

Workaround   There is no workaround.
CSCsl04115 CM call to CME when Put on Hold, CME Hears FastBusy instead of TOH
Symptom    Cisco IP Phone placed on hold hears fast busy instead of tone-on-hold.
Conditions   A Cisco IP Phone registered with a Cisco Unified CallManager Express (CME) may hear a fast busy tone when placed on hold. This can occur when interworking with Cisco Unified CallManager (CCM) as shown here:

IPPhoneA---CM---H323---CME---IpPhoneB

- Phone A calls Phone B
- Phone A puts Phone B on Hold.
- Instead of playing Tone On Hold, Phone B user hears a fast busy tone.
Workaround   This behavior was introduced in 12.4(15)T. Either downgrade the IOS version on the CUCME or configure music-on-hold (MOH) to be played from CUCM, instead of TOH.
CSCsk72582 Call in B-ACD drops if answered after hunting second time round
Symptom    Calls in B-ACD on CME router drops if the first round hunting is done through the hunt group lines. If the call is not answered, the caller is placed in the queue and hears an announcement with "all agents busy please hold " and so on. When the script hunts again after a timeout and this time, the call is answered, it drops the call completely. All phones in the hunt group will see a display of 1 call in queue for a few seconds before clearing.
Conditions   Call drops only after the 1st round of hunting. If the call is answered in the initial hunting, the call connects. Once the caller is in the queue and hears MOH, if the agent (hunt member) answers the call after that the call will drop.

Workaround   There is no workaround.
