http://www.cisco.com/univercd/cc/td/doc/product/access/acs_mod/1800fix/index.htm 

Determining the Software Version

To determine which version of the Cisco IOS software is currently running on your Cisco 1800 series (fixed) routers, log in to the router, and enter the show version EXEC command. The following sample output from the show version command indicates the version number on the second output line.

Router> show version Cisco IOS Software, C1800 Software (C1800-ADVENTERPRISEK9-M), Version 12.4(11)XW, EARLY DEPLOYMENT RELEASE SOFTWARE Copyright (c) 1986-2007 by Cisco Systems, Inc

Upgrading to a New Software Release

For general information about upgrading to a new software release, see the Software Installation and Upgrade Procedures, which are located on Cisco.com.

Feature Set Tables

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.

Caution Cisco IOS images with strong encryption (including, but not limited to 168-bit (3DES) data encryption feature sets) are subject to U.S. 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 because of U.S. 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.

The feature set tables have been removed from the Cisco IOS Release 12.4 release notes to improve the usability of the release notes documentation. 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://www.cisco.com/go/cfn

For frequently asked questions about Cisco Feature Navigator, see the FAQs at the following URL:

http://www.cisco.com/support/FeatureNav/FNFAQ.html

Determining Which Software Images (Feature Sets) Support a Specific Feature

Resolved Caveats - 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 - Release 12.4(11)XW5

There are no open caveats in this release.

Resolved Caveats - 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 times CSCsk60054 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 service CSCsk22265 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 platforms CSCsk25651 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 codec CSCsj81363 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 platform CSCse14595 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 configured CSCsk52683 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 broken CSCsj88854 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

Symptom    Call is disconnected when another ephone is reset or unregisters.

Conditions   The call on the ephone-dn shared by other phone as non monitor button is disconnected if it is reset or unregisters from the CCME.

Workaround   There is no workaround.

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

Symptom    This Cisco Bug ID identifies vulnerability in Cisco's implementation of Extensible Authentication Protocol (EAP) that exists when processing a crafted EAP Response Identity packet. This vulnerability affects several Cisco products that have support for wired or wireless EAP implementations.

This vulnerability is documented in the following Cisco bug IDs:

* Wireless EAP - CSCsj56438
* Wired EAP - CSCsb45696 and CSCsc55249

CSCsk66907 %SYS-3-CPUHOG: due to Skinny MOH Server process

Symptom    PU Hog due to Skinny MOH Server causing phones to unregister:

%SYS-3-CPUHOG: Task is running for (xxx)msecs, more than (xxx)msecs
(xxxxxx),process = Skinny MOH Server.x

Conditions   Occurs if Music on Hold (MOH) is being streamed from flash in IOS 12.4(11)XW3.

Workaround   Use the live feed option by plugging in a CD player or iPOD or any such device to the MOH port on the UC500. Disable MOH from flash that implies tone on hold (or beep on hold).

CSCsi60392 CME does not send SIP NOTIFY DTMF to CUE-AA after txfer from CUE-VM

Symptom    No response to DTMF inputs during Auto Attendant session.

Conditions   Remote caller (across SIP Trunk) leaves voice message on local subscriber's CUE and then gets transferred to local AA. AA requests DTMF input for prompts played but this is not detected by CUE.

Workaround   There is no workaround.

CSCsl12443 CME: TNP phones may experience one way audio

Symptom    IP phone with FXO trunk config may experience intermittent one way audio. Debug ephone detail will show the following error:

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

dial-peer voice 9191916 pots
description #1/1:16#0# INUSE 163

Using 2811
Cisco IOS versions: 12.4(17.4)PI1b and 12.4(17.4)PI1a

Workaround   There is no workaround.

CSCsk63037 CME 4.2 has broken caller ID feature

Symptom    Calling name is corrupted for ISDN calls on CME.

Conditions   The problem can be seen for every call.

Workaround   There is no workaround.

CSCsk95708 10 to 30 sec delay in starting media in secure meet-me conference

Symptom    SCCP messages are delayed by a few seconds for secure calls, this could effect secure dspfarm secure analog endpoints.

Conditions   Using secure dspfarm or analog endpoints.

Workaround   There is no workaround.

CSCsk42180 Few Objects of CISCO-LICENSE-MGMT-MIB giving wrong values during SNMP wa CSCsj94818 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.

CSCec12299 Corruption of ext communities when receiving over ipv4 EBGP session

Symptom    EIGRP-specific Extended Community 0x8800 is corrupted and shown as: 0x0:0:0.

Conditions   This symptom is observed when EIGRP-specific Extended Community 0x8800 is received via an IPv4 EBGP session on a CE router. This occurs typically in the following inter-autonomous system scenario:

ASBR/PE-1 <----> VRF-to-VRF <----> ASBR/PE-2

Workaround   Use a configuration such as the following to remove extended communities from the CE router:

router bgp 1
address-family ipv4 vrf one
neighbor 1.0.0.1 remote-as 100
neighbor 1.0.0.1 activate
neighbor 1.0.0.1 route-map FILTER in

Conditions   This happens only when the transcoding calls on IPIP Gw are disconnected abruptly or ungracefully.

Workaround   There is no workaround.

CSCsg40567 Memory leak found with malformed tls/ssl packets in http core process

Symptom    Malformed SSL packets may cause a router to leak multiple memory blocks.

Conditions   This symptom is observed on a Cisco router that has the ip http secure server command enabled.

Workaround   Disable the ip http secure server command.

CSCsg69022 c1700 router crash @ nv_write_internal

Symptom    When a user configures the no telephony-service command, router crashes at running configuration generation.

Conditions   This symptom is highly unreproducible, but there is a potential race condition between the running configuration generation and the no telephony-service command.

Workaround   There is no workaround.

CSCsh65321 Phones fail to do secure authentication in 12.4(12.12)PI6

Symptom    Non-7921 phones will not register securely to CME.

Conditions   The cnf files for the non-7921 phones have their processNodeName field under CAPF server set to the CAPF IP address. A null value in this field will allow the phones to register securely.

Workaround   Remove the processNodeName parameter in the capf server of the phone's cnf file.

CSCsh73754 SmartPorts: PC connected to an IP phone cannot connect to WAN CSCsh80217 No Audio Path after REFER from xto to xee in a Meetingplace scenario

Symptom    No audio heard on Caller IP phone

Conditions   Meeting Place RSNA environment

Workaround   Yes Fallback image available

CSCsh81876 Traceback & crash if guest mode and multiple vlans

Symptom    In case the platform supported number of BSSIDs is 8 then configuring any ssid which comes in the 9th to 16th order in "sh run" as "guest-mode" results in a software crash. In general, if the platform supported BSSIDs considered as X and the maximum supported SSIDs considered as Y then configuring any ssid which comes in the X+1 to Y order(in "sh run") as "guest-mode" results in crash. Problem is not seen on platforms on which supported number of BSSIDs is 16.

Workaround   Configure only that ssid as "guest-mode" which comes in the order 1st to X(platform supported BSSIDs) in "sh run" i.e. if the number of platform supported BSSIDs is 8 then configure any ssid as "guest-mode" which comes in the order 1st to 8th in "sh run".
