Hardware Supported

Cisco IOS Release 12.4(11)XW supports the following Cisco 3800 series routers:

•Cisco 3825

•Cisco 3845

For descriptions of existing hardware features and supported modules, see the hardware installation guides, configuration and command reference guides, and additional documents specific to the Cisco 3800 series routers, which are available on Cisco.com at the following location:

http://www.cisco.com/univercd/cc/td/doc/product/access/acs_mod/3800/index.htm 

Determining the Software Version

To determine which version of Cisco IOS software is currently running on your Cisco 3800 series router, 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.

Router> show version
Cisco Internetwork Operating System Software
IOS (tm) C3800 Software (C3800-Y7-MZ), Version 12.4(11)XW, EARLY DEPLOYMENT RELEASE SOFTWARE (fc1)
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. Release 12.4(11)XW supports the same feature sets as Releases 12.4 and 12.4(11)T, but Release 12.4(11)XW includes new features supported by the Cisco 3800 series routers.

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 Cisco IOS Release 12.4(11)XW.

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(4)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.

New Software Features in Cisco IOS Release 12.4(11)XW

The following new features are supported on the Cisco 3800 series router in Cisco IOS Release 12.4(11)XW:

•FXO Delayed Caller ID Delivery

•H.323 Name Display

•Universal Voice Transcoding Support for IP-to-IP Gateways

•Voice Quality Enhancements

•Session Border Controller Enhancements for H.323-SIP and SIP-SIP Supplementary Services, Transcoding Optimization and Firewall Integration

Note Due to performance issues when using telephone features, the new features of CME and SRST will be released in the next rebuild for 12.4(11)XW. TAC support for CME and SRST will only be available with with 12.4(11) XW1 or later rebuilds.

FXO Delayed Caller ID Delivery

Before Cisco IOS Release 12.4(11)XW, Foreign Exchange Office (FXO) Caller ID in North America was delivered between the first and second ring cycles based on the GR-30-CORE standard. FXO software was configured to wait for Caller ID delivery before initiating the call setup for the next leg. As a result, the destination endpoint did not start ringing until after 1.5 to 2 ring cycles on the FXO port.

Beginning with Cisco IOS Release 12.4(11)XW, the immediate keyword has been added to the connection plar opx command. When this keyword is included in the syntax, the FXO port sets up calls immediately so that the ring-cycle discrepancy is eliminated, and the perception of the number of rings is the same for both the caller and the called party. When the Caller ID is available, it is forwarded to the called number. If the called party answers the call before the Caller ID has been forwarded, then the Caller ID update will not be forwarded to the display at the called party.

Note This feature does not require that Caller ID be enabled. If Caller ID is enabled, it will be handled as described here. The fundamental benefit of this enhancement is to ring the destination party immediately.

This feature is critical for service organizations that have service level agreements (based on calls being answered within a specified number of ring cycles) with their customers.

H.323 Name Display

Calling name display information may be populated in ISDN messages in the Display Information Element (IE) of a Q.931 Setup or Notify message, or in the Facility IE of a Q.931 Setup or Facility message. The Cisco IOS gateway places this information into the same field of the corresponding H.323 message.

Cisco Unified Communications Manager (CUCM) interprets calling name information (for purposes of name display on IP phones registered with CUCM) only in the Display IE of the H.323 Setup and Notify messages. Name display information delivered in an H.323 Facility message is not interpreted by CUCM. Some ISDN switch types (for example, NI2) send a "name-to-follow" indication in the Q.931 Setup message and deliver the calling name subsequently in the Facility IE of a Q.931 Facility message. When a Cisco IOS gateway is connected to such an ISDN switch, and interoperating with CUCM using the H.323 protocol, CUCM is unable to display calling name on the IP phones.

Beginning with Cisco IOS Release 12.4(11)XW, two new modes of operation are introduced on the Cisco IOS gateways:

•When a Q.931 Setup message with a "name-to-follow" indication is received from an ISDN switch, an H.323 Setup message with no name information is sent to CUCM. When the subsequent Q.931 Facility message is received with calling name information, it is mapped by the gateway to an H.323 Notify Display IE so that CUCM can interpret it correctly and display it on the IP Phone.

•When a Q.931 Setup message with a "name-to-follow" indication is received from an ISDN switch, the gateway can buffer the setup message until the subsequent Q.931 Facility message with calling name information is received. The name information from the Q.931 Facility message is now placed into the H.323 Setup message Display IE and sent to CUCM. If the buffer timer expires before the Q.931 Facility message is received, an H.323 Setup is sent with no name information and, if it subsequently arrives, the information is sent on using an H.323 Notify message.

This software operation is transparent to CUCM and works with all releases, although CUCM 4.2 or later is recommended.

To enable the H.323 Display feature without buffering for ISDN trunks that use the Facility message to deliver Name Display information, configure the following:

At the voice service level:

voice service voip
 h323
 h225 display-ie ccm-compatible

At the voice class level:


voice class h323 1
 h225 display-ie ccm-compatible [system]

To enable the H.323 Display feature with buffering for ISDN trunks that use the Facility message to deliver Name Display information, additionally configure the following:

interface Serial0/3/0:23
no ip address
encapsulation hdlc
isdn switch-type primary-ni
isdn incoming-voice voice
isdn map address *. plan isdn type unknown
isdn supp-service name calling
isdn bind-l3 ccm-manager
no cdp enable

http://www.cisco.com/en/US/products/ps6706/products_feature_guide09186a0080756fd1.html

Session Border Controller Enhancements for H.323-SIP and SIP-SIP Supplementary Services, Transcoding Optimization and Firewall Integration

Session Border Controller Enhancements for H.323-to-SIP and SIP-to-SIP Supplementary Services enhances terminating and re-originating both signaling and media between VoIP and Video networks by supporting H.323 (ECS)-to-SIP (Refer/302 & Re-Invite based) Supplementary Service, Transcoder optimization, and RAS message enhancements.

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.

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

This Cisco Security Response is available at the following link: http://www.cisco.com/warp/public/707/cisco-sr-20071019-eap.shtml.

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

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

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

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".

CSCsh89887 One way voice path with h/w conference on ephone-dn w/o preference 0 CSCsi03314 test ecdsa display-stats command not displaying output CSCsi04538 Router crash with memory corruption when configure cert-upgrade auth mod

CSCsi15740 Memory leak in basic ICD call CSCsi22430 B-ACD Crashes CME 4.2

Symptom    CME could crash when running B-ACD script while call monitoring is enabled.

Conditions   CME could crash if (1) call monitoring is turned AND (2) an incoming call gets routed to any application scripts other than the Default Session.

Workaround   The work around is to manually disable callmon before running any non-default applications.

CSCsi27400 Memory leak in TGW for basic SRTP-TLS SIP call

CSCsi31667 SIP Registrations sent to Service Provider Proxy for Internal extensions CSCsi34163 Restore: Radar Detection for non-European regions. CSCsi42596 router crash when using MeetMe conference with 13 participants CSCsi44268 $$TS SIP trunk to AA to SIP phone disconnected

Problem Description: Call from sip-trunk to CRS/AA sip-phone, call disconnected after 19 seconds.

Symptom    The issues observed after V124_11_3_8_PI1A onwards. there was a major ida_t_pi1_atg sync to PI6 occurred in this label.

1. Two reINVITEs sent by originating gateway, received "500 Internal Server Error" on the 2nd reINVITE.

2. Terminating CME does not ACK on the reINVITE(unhold) received.

Root Cause:    In Xfering_SetupDone() when case of CS_ACTIVE, remove calling AFW_Leg_Resume() again when handling special delayDisconnect call-info in REFER. This code is no longer needed since AFW now unhold the sip XEE before shelbourne hairpin.

Workaround   There is no workaround.

CSCsi44465 change CME version from 4.1 to 4.2

CSCsi44549 Router crashes during pings when QoS+NAT+FW+IPSEC+GRE are configured CSCsi47359 Crash seen in AFW_Process at the customer site CSCsi48062 H323--H323--SIP call fails with media transcoder high-density

Symptom    On the IPIPGW, an H.323-to-H.323 call fails to complete call setup.

Conditions   This problem happens when this call requires transcoding on the IPIPGW and media transcoder high-density is configured for use. Also, after TCS and MSD negotiation, only one of the OGW and TGW sides initiates the OLC negotiation, but not both.

Workaround   The workaround is not to use media transcoder high-density on the dial-peers which would handle such described interconnected calls.

CSCsi51441 uclient cannot ping to gateway via non-native vlan Please refer Release-note enclosure attached to the DDTS CSCsg58791. CSCsi52410 Add version 6.0 to the available CCM version on dspfarm CSCsi53006 Router crash in cmm_crs_proc_tr_call_trans_req

Symptom    CME with UCCX integration could crash at the following function:

cmm_crs_proc_tr_call_trans_req()

Conditions   The crash would only occur in very rare condition. Indeed the problem is difficult to reproduce. This could happen when an sccp endpoint attempts a consult transfer.

Workaround   There is no workaround.
