Upgrading to a New Software Release

For general information about upgrading to a new software release, refer to 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)XJ supports the same feature sets as Releases 12.4 and 12.4(4)T, but Cisco IOS Release 12.4(11)XJ includes new features supported by the Cisco 1700 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. Please 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 Release 12.4(11)XJ 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)XJ" indicates that the feature was introduced in 12.4(11)XJ. 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(4)T and Release 12.4(4)T Cisco IOS documentation.

•CME SIP Features

•SIP REFER

CME SIP Features

MoH, Dialing, Line Updates, Presence with BLF, Provisioning New Phones

A presence service, as defined in RFC 2778 and RFC 2779, is a system for finding, retrieving, and distributing presence information from a source, called a presence entity (presentity), to an interested party called a watcher. When you configure presence in a Cisco Unified CME or Cisco Unified SRST system with a SIP WAN connection, a phone user, or watcher, can monitor the real-time status of another user at a directory number, the presentity.

http:/www.cisco.com/univercd/cc/td/doc/product/voice/its/cme41/cme410ft.htm

SIP REFER

Outside the Scope of a Dialog Created with an INVITE

Out-of-dialog REFER (OOD-R) allows remote applications to establish calls by sending a REFER message to a SIP gateway without an initial INVITE.

CSCsh12480

Cisco IOS software configured for Cisco IOS firewall Application Inspection Control (AIC) with a HTTP configured application-specific policy are vulnerable to a Denial of Service when processing a specific malformed HTTP transit packet. Successful exploitation of the vulnerability may result in a reload of the affected device.

Cisco has released free software updates that address this vulnerability.

A mitigation for this vulnerability is available. See the "Workarounds" section of the advisory for details.

This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20080924-iosfw.shtml.

CSCsg91306

Multiple vulnerabilities exist in the Session Initiation Protocol (SIP) implementation in Cisco IOS that can be exploited remotely to trigger a memory leak or to cause a reload of the Cisco IOS device.

Cisco has released free software updates that address these vulnerabilities. Fixed Cisco IOS software listed in the Software Versions and Fixes section contains fixes for all vulnerabilities addressed in this advisory.

There are no workarounds available to mitigate the effects of any of the vulnerabilities apart from disabling the protocol or feature itself, if administrators do not require the Cisco IOS device to provide voice over IP services.

This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20080924-sip.shtml.

Open Caveats - Cisco IOS Release 12.4(11)XJ2

There are no open caveats in this release.

Resolved Caveats - Cisco IOS Release 12.4(11)XJ2

CSCec12299

Devices running Cisco IOS versions 12.0S, 12.2, 12.3 or 12.4 and configured for Multiprotocol Label Switching (MPLS) Virtual Private Networks (VPNs) or VPN Routing and Forwarding Lite (VRF Lite) and using Border Gateway Protocol (BGP) between Customer Edge (CE) and Provider Edge (PE) devices may permit information to propagate between VPNs.

Workarounds are available to help mitigate this vulnerability.

This issue is triggered by a logic error when processing extended communities on the PE device.

This issue cannot be deterministically exploited by an attacker.

Cisco has released free software updates that address these vulnerabilities. Workarounds that mitigate these vulnerabilities are available.

This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20080924-vpn.shtml.

CSCsd85587

A vulnerability has been discovered in a third party cryptographic library which is used by a number of Cisco products. This vulnerability may be triggered when a malformed Abstract Syntax Notation One (ASN.1) object is parsed. Due to the nature of the vulnerability it may be possible, in some cases, to trigger this vulnerability without a valid certificate or valid application-layer credentials (such as a valid username or password).

Successful repeated exploitation of any of these vulnerabilities may lead to a sustained Denial-of-Service (DoS); however, vulnerabilities are not known to compromise either the confidentiality or integrity of the data or the device. These vulnerabilities are not believed to allow an attacker will not be able to decrypt any previously encrypted information.

The vulnerable cryptographic library is used in the following Cisco products:

–Cisco IOS, documented as Cisco bug ID CSCsd85587

–Cisco IOS XR, documented as Cisco bug ID CSCsg41084

–Cisco PIX and ASA Security Appliances, documented as Cisco bug ID CSCse91999

–Cisco Unified CallManager, documented as Cisco bug ID CSCsg44348

–Cisco Firewall Service Module (FWSM)

This vulnerability is also being tracked by CERT/CC as VU#754281.

Cisco has made free software available to address this vulnerability for affected customers. There are no workarounds available to mitigate the effects of the vulnerability.

This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20070522-crypto.shtml.

---

Note Another related advisory is posted together with this Advisory. It also describes vulnerabilities related to cryptography that affect Cisco IOS. A combined software table for Cisco IOS only is available at http://www.cisco.com/warp/public/707/cisco-sa-20070522-cry-bundle.shtml and can be used to choose a software release which fixes all security vulnerabilities published as of May 22, 2007. The related advisory is published at http://www.cisco.com/warp/public/707/cisco-sa-20070522-SSL.shtml.

Open Caveats - Cisco IOS Release 12.4(11)XJ

There are no open caveats in this release.

Resolved Caveats - Cisco IOS Release 12.4(11)XJ

CSCse89321 DTMF path not getting confirmed in sip media forking call

Symptom    There is no end-to-end DTMF path confirmation.

Workaround   There is no workaround.

CSCsf26561 User portion of Diversion header is incorrect when calling through AA

Symptom    Tests on customer setup have revealed that PSTN to AA --> tx to SCCP phone--> CFWD to CUE/PSTN has an issue. The 302 Moved Temporarily from CME to BroadSoft has a Diversion header whose user portion is the private extension #, not the expanded DID # due to which the subsequent call fails.

Workaround   Remove the dialplan-pattern.

CSCsf32028 Host portion of Refer-To: header must be an Address of Record

Symptom    SIP trunking environments (for example, Cbeyond) need the URIs to carry Address of Record [AOR] in many SIP headers.

Workaround   There is no workaround.

CSCsg17289 DNS-SRV issues for SIP registrations

Symptom    Registrar, both the dial-peers would try to send a REGISTER request sequentially. When first Dial-peer (D1) is sending REGISTER Request, the registrar cache is empty. It first sends a DNS query (SRV). After getting the DNS Response, it updates the Registrar cache and sends the REGISTER request to Registrar R1. dns_count variable here is set to SIP_DNS_MODE.

When second dial-peer is sending REGISTER request, it finds the resolved IP address in registrar cache (R1) so it sends the REGISTER request to R1. dns_count variable here is set to SIP_NON_DNS_MODE. But both the REGISTER request fails as R1 is down.

As D1 is set to SIP_DNS_MODE, D1 would send a DNS query again with incremented dns_count to get any alternate Registrar and it gets R2. It sends REGISTER request to R2 and gets successfully registered. As D2 is set to SIP_NON_DNS_MODE, it does not retry the DNS query and simply backs off for period REG_EXPIRES/20.

Workaround   There is no workaround.

CSCsg18902 Blind transfer is not working on SIP trunk

Symptom    Blind transfer failed on SCCP endpoint over SIP trunk

Conditions   When session-target is configured but outbound-proxy is not configured.

Workaround   There is no workaround.

CSCsg30101 CME: dtmf-relay force rtp-nte CLI does not work

Symptom    The voice-class sip dtmf-relay force rtp-nte command does not work.

Conditions   Call comes from PSTN gw to CUE-AA, w/offer SDP of g711u, 100(NSE) CME invite's the CUE by offering g711u and NOTIFY for DTMF. CUE replies with g711u & NOTIFY for DTMF CME replies to the PSTN gw with only g711u codec with the software image.

As a result, rfc2833 is not negotiated and hence DTMF is sent raw inband. When PSTN caller presses DTMF digits after being prompted by AA, nothing works, since the CME cannot convert raw-inband DTMF to NOTIFY. With 12.4-4T3 the CME replied to the PSTN gw with g711u and rfc2833(PT=101).

Workaround   There is no workaround.

CSCsg39750 Spurious mem access/traceback while resetting sip phone with presence

Symptom    Spurious memory access and traceback is encountered while resetting the SIP phone (7961). After configuring presence with CME.BLF speed dial entries, the status is not updated for the watched phones.

Workaround   There is no workaround.

CSCsg46362 contact header incorrect in 302 message using sip-srst redirect mode

Symptom    The contact header ip address is incorrect in the 302 message sent by SIP SRST in redirect mode. As the result basic call fails in this mode. B2b mode is working okay.

Workaround   Use b2b mode.

CSCsg46411 CME does not send a REFER over SIP trunk for calls involving AA

Symptom    CME fails to send a REFER over the SIP trunk for calls coming into the CUE-AA and being transferred to a local extension.

Conditions   The CUE does a BYE-Also transfer and the CME is supposed to look at the Also: header and put that into the URI for REFER message.

Workaround   There is no workaround.

CSCsg51244 CME does not send 3xx messages for transfer --> forward scenarios

Symptom    CME does not send a 3xx message during call fwd if there was a call-transfer invoked before the call-forward happens.

Conditions   With only no suppl service sip refer configured on CME at global level, we do not see the CME sending a 3xx over the SIP trunk to BSFT, Instead, a wrong reINVITE (only g711u, no dynamic payload 101) is seen when the call is forwarded to B's mailbox. This could potentially cause DTMF issues for PSTN caller. For PSTN to extension-A(DID #) CFNA to A's voicemail, the CME does send a 3xx as expected. Therefore, when a transfer is done before a forward to voicemail happens, the CME does not send a 3xx.

Workaround   There is no workaround.

CSCsg51259 DTMF stops working after consult transfer to called party mailbox

Symptom    PSTN connects to extension A, A transfers to B, B's CUE voicemail answers due to CFNA, A does a full consult transfer to B's CUE voicemail.

Conditions   The call goes through fine, and the caller can leave a message for B, but DTMF fails even if signaling shows that 101 payload was negotiated for the SIP trunk. So if the caller wants to re-record or mark the message urgent, it does not work, although the message gets recorded.

Workaround   There is no workaround.

CSCek61666 Ephone DNs get stuck in SEIZE state under certain conditions

Symptom    : Ephone DNs gets stuck in seize state under certain conditions, particularly under the following sequence:

1. phone-A has multiple trunk-DNs configured. 

2. Call comes in on one of trunk-DN, say DN1. Call is answered and the 

   transfer button is pressed and another extension (DN3) is dialed. 

   The dialed extension answers the call.

3. At this time, the user on phone-A goes offhook on another trunk DN 

   (say DN2), and dials one digit.

4. The PSTN user who is connected to DN1 hangs up and so does DN3

The above sequence gets both channels of DN1 into SEIZE state.

Conditions   : The rootcause of the issue was narrowed down to trunkdial flag that is part of the skinnyCB structure which is maintained per-phone. So, when DN2 goes offhook this trunkdial flag is set. When trunkdial flag in ON, all state transitions in the DN is ignored in SkinnyUpdateCallState. So, all state transitions are ignored for DN1 when the call is being cleared because the trunkdial flag is set for the entire phone rather than the specific DN.

Workaround   CSCek61570 resolves this issue in the Cisco IOS 12.4(XC) throttle using a mechanism where the state transitions are not ignored it is not the active DN with trunkdial flag still in the skinnyCB structure. Make the trunkdial flag per-DN specific rather than per-phone.

CSCek37305 Cisco 7200 router crashes at get_hwidb_if_same

Symptom    Router crashes on unconfiguring T1 controller with interface configured for RTP priority.

Conditions   This is seen on 7200 NPE-G1 router loaded with 12.2(31.4.17)SB image

Workaround   A workaround is to ensure that the ip rtp priority or ip rtp reserve command is removed before deleting the interface.

CSCek39470 Router memory leak due to pak subblock chunk leaking with crypto+BVI

Symptom    Cisco IOS router running 12.4 may experience per packet memory leak due to pak subblock leak in Process memPool (not in IO mem pool). The symptom is: show proc mem 1 output seeing the first allocator's memory count is keep growing, and never decrease.

Conditions   The leak is observed with BVI (Bridge-group Virtual Interface) interface configured with crypto ipsec tunnels. Specifically when the router is doing decryption, then send the decrypted packet to BVI interface.

Workaround   Shutdown any BVI (Bridge-group Virtual Interface) if being used in a router with crypto ipsec configured.

CSCek45272 NAT overload failing with static mappings

Symptom    NAT overloading from inside source address to an outside interface may fail.

Conditions   The symptom was seen when translation ports were specified in an access-list associated to a route map and a second static NAT translation condition. Traffic which should have been NATed via the primary NAT overload statement failed because of the specified translation ports being used in second NAT translation condition. This occurred even though the traffic to be NATed did not meet the conditions of the second static NAT translation condition.

Workaround   Remove the ip nat inside source interface X overload statement and then re-add it. The AT translations will then worked correctly until the next router reload.

CSCek61570 Trunk dn stuck in seize/seize state and does not recover

Symptom    The ephone DN may get stuck in SEIZED state and one-way audio would occur afterwards.

Conditions   If another call is dropped during trunk dialing, the DN for this terminated call would move to seized state.

Workaround   Press ENDCALL softkey twice to move the seized DN to idle state after finishing the and trunk call. To work around the one-way audio issue, the call needs to be transferred out and then transferred back.

CSCek62099 MLP: PPPoE encap not applied to CEF switched non-MLP packets

Symptom    When PPP Multilink is enabled over a PPP over Ethernet (PPPoE) session, outbound packets are incorrectly sent without PPPoE headers. This causes them to be dropped.

Conditions   Symptom is observed in IOS version 12.4 on all software-forwarding router platforms. It only affects packets which are not multilink encapsulated (due to the bundle only having a single link).

Workaround   Either disable multilink PPP, or use the ppp multilink fragment delay interface command to force multilink headers to be applied to all outbound packets.

CSCir00074 Router crashes when casnDisconnect is set to true for pppoe session

Symptom    A router crashes when the casnDisconnect object is set to "true" for a PPPoE session.

Conditions   This symptom is observed on a Cisco 10000 series when you attempt to terminate the PPPoE session through SNMP by using the casnDisconnect object of the ISCO-AAA-SESSION-MIB.

Workaround   There is no workaround.

CSCir00530 CJ-Ph2:Entry missing in cefcModuleTable for a CJ PA in Escort slot

Symptom    Entry for Crackerjack PA missing from cefcModuleTable.

Conditions: SNMPGet on the table is issued.

Workaround   There is no workaround.

CSCsc48536 A router may reload unexpected due to bus error at ipnat_lock_nat

Symptom    A Cisco router may reload unexpectedly with a bus error exception.

Conditions   This symptom has been observed on a router with Network Address Translation (NAT) enabled.

Workaround   There is no workaround.

CSCsd50476 When channel-group configured serial interface goes down CSCse35510 OER 
misidentifying overlapping prefixes

Symptom    A serial link goes down.

Conditions: This symptom occurs when a T1/E1 controller that is configured with channel-group causes the serial link to go down. The CEM interface will not come up.

Workaround   There is no workaround.

CSCse46648 IP Address Getting Removed From Interface On Deleting Crypto Config

Symptom    IP address removal from a physical interface

Conditions   When IPSEC connection fails and the ip unnumbered config is applied on the virtual template

Workaround   Use cryptomaps, wit vtis, to configure the ip address on the physical interface and re attempt connection.

CSCse88584 Router proposes the default ISKMP policy if configured one does not matc

Symptom    Router is proposing the default ISAKMP policy if the configured one does not match

Workaround   There is no workaround.

CSCsf16536 IOSIPS - router crashes at tw_timer_start with sig action 
denyFlowInline

Symptom    A Cisco IOS router may experience a unexpected reload.

Conditions   This problem occurs when the router has IPS (Intrusion Prevention Systems) configured, and one or more attack signatures has the denyFlowInline action enabled.

Workaround   Do not enable the denyFlowInline action for any IPS signatures.

CSCsf27796 1841 router reloads at retparticle with %SYS-2-BADSHARE error 

Symptom    A 1841 router may reload at retparticle with %SYS-2-BADSHARE errors.

Conditions   The router must be running crypto traffic using a dialer interface over a GSHDSL interface.

Workaround   There is no workaround.

CSCsg02881 MLP: Bandwidth of down MLP group should be sum of member bandwidths

Symptom    The bandwidth of a multilink group interface that is down does not reflect the actual bandwidths of the links that are configured as members of the multilink group. In Cisco IOS Release 12.4(8) and later, the multilink interface bandwidth reflects the bandwidth of the last link in the bundle prior to going down. In earlier versions, the bandwidth is restored to 100000 Kbps.

Conditions   This symptom is observed when the multilink interface is down. The bandwidth is correct when the multilink bundle is up.

Workaround   There is no workaround.

CSCsg10159 Successive Default route ctrl fails on different link but on same router

Symptom    Default route withdrawn message is send from BR immediately after successful control of default roue. And prefix goes to DEFAULT state.

Conditions   This only happens if OER system has only one BR and static routing protocol is used. The bug is limited to default route prefix only.

Workaround   Use non-default route prefix.

CSCsg12813 Speech loss after receiving MDCX from PGW

Symptom    A Cisco AS5400 gateway may change it's RTP sequence numbers after receiving a MDCX command. The RTP Stream SSRC is always the same but the Sequence Number seems to be randomly initiated again.

Conditions   MGCP receives a modification request from PGW for echo cancellation 3 seconds after the call is established.

Workaround   There is no workaround.

CSCsg16186 SCMabort Event crash seen on NPE-G2

Symptom    System may crash during bootup.

Conditions   When PA-MCX-8TE1+ is in the system and 256MB IO Memory is configured.

Workaround   Reduce IO memory in the configuration.

Further Problem Description: You should see SCM Abort message in the crash info file.

CSCsg16748 ABR deletes OSPF type 3 LSA after it received max-aged type 2 LSA

Symptom    In the situation ABR has both type 2 LSA and type 1 LSA for a prefix, ABR deletes type 3 LSA if it received max-aged type 2 LSA.

Workaround   The workaround of this issue is configuring timers lsa arrival and timers throttle lsa all or timers lsa-interval.

CSCsg33172 IPS 5.0: Provide more informational error message XML and names

Symptom    A few inconsistent error message.

Conditions   Some SDEE messages aren't consistent with SDEE schema.

Workaround   There is no workaround.

CSCsg38907 rip - redistribute static: redistributed prefixes have metric 16

Symptom    Under some conditions redistributed static routes are sent out with metric 16

Conditions   * the static route for a subnet of a classfull network has a next-hop in another classfull network that is not enabled under rip. The rip update is sent out to a subnet within the same major network that the prefix of the static is about

Workaround   Enable the next-hop network under rip. Configure distribute-list to filter the update.

CSCsg39216 ezvpn tunnel traffic with acl keyword is not excluded from NAT

Symptom    When EZVPN client is configured with "acl" keyword, the tunneled (vpn) traffic also gets NATed.

Conditions   This only happens if there is a NAT configuration that includes the interesting VPN traffic. The tunneled traffic should be bypassed from NAT when the VPN is up.

Example:

crypto ipsec client ezvpn hwclient

 connect auto

 group cisco key cisco123

 mode network-extension

 peer 10.1.1.1

 acl 103

access-list 103 permit ip 192.168.100.0 0.0.0.255 192.168.1.0 0.0.0.255

This occurs when the following is true:

1) ezvpn client is configured

2) interesting tunnel traffic is defined using the "acl" keyword under global ezvpn configuration

3) NAT is configured

Workaround   Use crypto ipsec ezvpn client <ezvpn-name> inside on the interface instead of acl keyword under ezvpn global configuration.

CSCsg39961 crash sending pki request to CA CSCsg43460 Improve NPE-G2 ENVM handling

Symptom    A router may unexpectedly reload when trying to send a PKI request to a CA.

Conditions   The router must be configured with crpyto PKI trustpoints.

Workaround   Because this is a 1 byte redzone overrun, the following will prevent the crashes, and will display error messages instead. First, to prevent the usage of chunks, configure no memory lite. Second, configure exception memory ignore overflow processor to correct the redzone overrun.

CSCsg46546 Erroneous alerting during pickup with CSCek58324 scenario

Symptom    Pickup will result in alerting from the pickup target instead of connected.

Conditions   Two calls come into a trunk monitor dn. The first one to come in is answered. The second one is then answered on the same phone using the line button. Another phone uses the pickup softkey to dial the first incoming call, which is now on hold.

Workaround   This issue only appears to occur on the second scenario of the above after a router reload.

CSCsg47834 NACK is observed for Open voice channel command

Symptom    NACK message may be received from 5510 DSP in response to Open Voice Channel command sent by the Cisco IOS software.

2568288: Oct 24 13:11:33.240: //-1/xxxxxxxxxxxx/HPI/[]/hpi_tx_global_debug_info: 

    DSP 3/0x3  port  INVALID_CHANNEL_STATE(85), info 0x01(1) 

    DSP 3/0x00000003 port  mode CLOSED(1), state UNDEFINED(133), NACKed message 
74/0x4A @0 

    DSP message header 0008 0003 004A 0001 Payload: 0x0000 0x0000 0xFFFF 0x0000 

Conditions   This problem may be observed when a same 5510 DSP is used as a Transcoding and Voice Termination resource.

Workaround   

1) Disable Transcoding

(or)

2) Make sure that the Transoding and Voice Termination are on different DSP(s).

This can be performed by configuring the maximum number of transcoding sessions to a value such that it would require a multiple of 240 DSP credits.

Example 1:

In the following configuration each transcoding session (complexity=high) will require 40 DSP credits. In order to use a multiple of 240 credits, we need to set the maximum transcoding sessions to 6 (6 * 40 = 240) or any multiple of 6.

dspfarm profile 1 transcode

 codec g711ulaw

 codec g729r8

 associate application SCCP

Router(conf-t)#dspfarm profile 1 transcode

Router(config-dspfarm-profile)#maximum sessions 6

Example 2:

In the following configuration each transcoding session (complexity=medium) will require 30 DSP credits. In order to use a multiple of 240 credits, we need to set the maximum transcoding sessions to 8 (8 * 30 = 240) or any multiple of 8.

dspfarm profile 2 transcode

 codec g711ulaw

 codec g711alaw

 codec g729ar8

 codec g729abr8

 associate application SCCP

Router(conf-t)#dspfarm profile 2 transcode

Router(config-dspfarm-profile)#maximum sessions 8

Use show voice dsp group all command to verify DSP resource allocation.

---

Note Each 5510 DSP has 240 Credits. This work-around cannot be implemented if the router has only one PVDM2-16 which has only one DSP.

---

CSCsg48183 Unforeseen ARP request send from all interfaces

Symptom    A router may unexpectedly send an ARP request from all its active interfaces to the nexthop of the network of an SNMP server.

Conditions   This symptom is observed on a Cisco router that has the snmp-server host command enabled after any of the following actions occur:

–Reload the router.

–A switchover of the active RP occurs.

–Enter the redundancy force-switchover main-cpu command.

Workaround   There is no workaround.

CSCsg57228 IPS5.0: c871 reloads using IOS-S222 package file

Symptom    Router crashes loading the IOS signature package file

Conditions   Appeared to happen the most on the Cisco 871 and Cisco 2600 platforms.

Workaround   There is no workaround.

CSCsg68199 Trunk DN offhook is not propagated to a phone already in dial out mode

Symptom    Two IP Phones A and B are registered with Cisco CallManager Express; these phones share two trunk DNs 1 & 2. If Phone-A goes offhook on DN-1 and Phone-B immediately goes offhook on DN-2. This condition should show the DN-2 button on Phone-A as busy which is not happening.

Conditions   This happens only when trunk DNs are used and the they go offhook in quick succession on different phones and are in dialing mode.

Workaround   There is no workaround.

CSCsg68711 Incoming call in background does not audibly ring after transfer commit

Symptom    Phone does not ring for the second incoming call after committing transfer at alert for the first call.

Conditions   While transferring a trunk DN call, a call comes in. After committing the transfer at alert, the incoming call still doesn't ring on the phone.

Workaround   There is no workaround.

CSCsg70221 DTMF through the hairpin of a trunk DN does not work

Symptom    DTMF tones are being suppressed to prevent duplicate DTMF tones from being extended to an SCCP controlled VG224 port. This problem is direct result of a fix implemented for correct CSCsf98754. The lack of DTMF prevents IVR devices from working correctly

Conditions   PSTN -- FXO --- CME GATEWAY --- VG224/FXS --- IVR

A call comes into a FXO port that is part of a trunk group and gets transferred to an extension that is hanging off of a vg224. DTMF is not relayed to the end point

Workaround   Set the transfer system to full blind to prevent the blocking of the DTMF.

CSCsg70355 Adopt new default summer-time rules from Energy Policy Act of 2005

Symptom    Starting in calendar year 2007, daylight savings summer-time rules may cause Cisco IOS to generate timestamps (such as in syslog messages) that are off by one hour.

Conditions   The Cisco IOS configuration command, clock summer-time zone recurring, uses United States standards for daylight savings time rules by default. The Energy Policy Act of 2005 (H.R.6.ENR), Section 110 changes the start date from the first Sunday of April to the second Sunday of March, and it changes the end date from the last Sunday of October to the first Sunday of November.

Workaround   A workaround is possible by using the clock summer-time configuration command to manually configure the proper start date and end date for daylight savings time. After the summer-time period for calendar year 2006 is over, one can for example configure:

clock summer-time PDT recurring 2 Sun Mar 2:00 1 Sun Nov 2:00

(this example is for the US/Pacific time zone)

CSCsg73806 Runaway debugs: AFW_Module_ObjectCount pCallIndSs

Symptom    A router may display the following message to the console repeatedly:

AFW_Module_ObjectCount pCallIndSs 1

This is a cosmetic error. With the fix, this message will only be seen with debugs enabled.

Conditions   This is seen on voice routers.

Workaround   There is no workaround.

CSCsg78801 4.x MinHits or 5.0 event-count not summarizing correctly

Symptom    Min hit or event count not resetting correctly

Conditions   Will fire signature on 1st occurrence of event, but never resets correctly so may or may not continue to fire signature.

Workaround   There is no workaround.

CSCsg90212 VSA: Add code to handle CRNG failure interrupt

Symptom    When VSA encounters a Continual RNG failure, the IOS will print the message

VSA encountered CRNG failure

Workaround   There is no workaround.
