---

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

---

Note H.323 name delivery is supported only on the first voip dial-peer used. If the call setup is unsuccessful on the first dial-peer, but successful on the second one, the calling name will not be delivered.

---

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:

At the voice service level:

voice service voip

h323

h225 timeout ntf <50-5000>

h225 display-ie ccm-compatible

At the voice class level:

http://www.cisco.com/en/US/docs/ios/12_4t/12_4t15/vqmetric.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.

CSCek52673 Single crafted udp packet reloads router with dhcp server

Symptom    A router that has DHCP server enabled could reload after receiving a malformed UDP packet.

Workaround   There is no workaround.

CSCek71149 Error message when dir is issued

Symptom    "Error getting file system status (Unknown error 0) or (Bad file number)" was observed when dir <archive/system/tmpsys:> was issued. The rest of the file systems have no problem (i.e. dir nvram/flash/usbtoken0:... etc)

Conditions   Load routers with problem releases.

Workaround   There is no workaround.

CSCsg42546 Reload when MGCP CRCX has sRTP and V150 params in LCO

Symptom    An MGCP gateway reloads when receiving Secure Real-Time Transport Protocol (SRTP) and V.150 parameters in the local connection options of a Create Connection (CRCX) message.

Conditions   This symptom has been observed when the gateway is configured to use SRTP and V.150 protocols.

Workaround   Disable the use of either SRTP or V.150 protocol in the gateway.

CSCsj32422 CBWFQ:Unable to reconfigure the policy map after exceeding the 
bandwidth

Symptom    Once policy map is configured and bandwidth is exceeded while dividing amongst the classes, re-configuration of the policy map is not possible.

Conditions   Create a policy map, exceed the bandwidth amongst the classes (e.g. try to divide more than 75% in CBWFQ).

Workaround   Don't exceed the bandwidth while configuring the policy map.

CSCsj50773 High cpu when querying ipRouteTable MIB

Symptom    Performing the snmpwalk on the ipRouteTable MIB may cause high CPU and reloads.

Conditions   This symptom is observed on a router that is running Cisco IOS Release 12.4(13b) or later releases.

Workaround   Create a view that excludes the ipRouteTable:

snmp-server view cutdown 1.3.6.1.2.1.4.21 exclude

snmp-server view cutdown internet included

snmp-server community <comm> view cutdown RO

This view restricts the objects that the NMS can poll. It excludes access to the ipRouteTable, but allows access to the other MIBs.

CSCsj82622 Crash editing ACL cce_dp_named_db_ip_access_list_impure

Symptom    A router may crash when you configure an access control list (ACL) that has at least 50-60 ACEs (about 100 nodes) that is used in policy maps that are already applied to an interface or when you boot the router after having made the configuration change. When the crash occurs, the following error message is generated: %ALIGN-1-FATAL: Corrupted program counter pc=0x0 , ra=0x0 , sp=0x66EFB8A0

Conditions   This symptom is observed on a Cisco 7200 series that runs Cisco IOS Release 12.4(15)T or Release 12.4(15)T1.

Workaround   There is no workaround.

CSCsk27147 SNMP stops responding while polling from CISCO-MEMORYPOOL-MIB

Symptom    The following SNMP is incorrectly generated:"%SNMP-3-INPUT_QFULL_ERR: Packet dropped due to input queue full". This issue is affecting the CISCO-MEMORYPOOL-MIB instead.

Conditions   Occurs on a Cisco 2600 series router running Cisco IOS Release 12.4(11)T3. The router keeps dropping SNMP packets. The log shows that the packets are dropped because of the input queue being full. Although the utilization is sometimes high, this could not be the root cause, as the router keeps dropping packets regardless of the current utilization. Also, the snmp process takes 5-20% of the CPU load.

Workaround   Exclude ciscoMemoryPoolMIB from your query with the following commands:

snmp-server view public-view iso included

snmp-server view public-view ciscoMemoryPoolMIB excluded.

Apply this view to the RW community string. This view will exclude only ciscoMemoryPoolMib, all other MIBs will be available.

CSCsk39642 router crash when copying saved config to running config

Symptom    A router crashes.

Conditions   This symptom is observed when you are running Cisco IOS Release 12.4(17) or Release 12.4T and when you copy the saved configuration to the running configuration.

Workaround   There is no workaround.

CSCsk94676 dlsw with tbridge, COMMON_FIB-4-FIBIDBMISMATCH

Symptom    Transparent bridging into DLSw does not work.The following messages are displayed:

*Jan 29 19:00:50.727: %COMMON_FIB-4-FIBHWIDBMISMATCH: Mis-match between hwidb DLSw Port0 (ifindex 5) and fibhwidb GigabitEthernet2/3 (ifindex 5)-Traceback= 407C7004 407C8A38 407C7CEC 407C7EE4 413C9900 41BCE138 41BCCD54 41BCCFA8 41BCA330 413C0128 413C0114

Conditions   When using DLSw+ together with transparent bridging.

Workaround   For a workaround, all transparent bridging commands related to dlsw can be replaced with DLSW Ethernet redundancy.

i.e.

As global command:

no dlsw bridge-group X

and on the interface:

no bridge-group X

on the interface replace it with:

dlsw transparent redundancy-enable 9999.9999.9999

CSCsl70722 Router crash polling rttmon mib with active IP SLA probes

Symptom    A router running Cisco IOS may crash due to watchdog timeout.

Conditions   Occurs when IP SLA probes are configured and active for a period of 72 weeks. After this much time has passed, polling the rttmon mib for the probe statistics will cause the router to reload. Then the problem will not be seen again for another 72 weeks.

Workaround   There is no workaround.

CSCsm17281 Router crashes when adding ACL line to Service Policy

Symptom    Device running 12.4(17.6)T will crash after adding line to an access-list attached to a service policy

Workaround   There is none.

CSCsm77199 DATACORRUPTION-1-DATAINCONSISTENCY HTTP_FIND_FLASH_FILE

Symptom    If the HTTP secure server capability is present, Switch shows the error message "%DATACORRUPTION-1-DATAINCONSISTENCY: copy error" with tracebacks after initializing the supervisor. This error message can be verified in show logging output.

Conditions   ip http server is configured.

Workaround   Configure no ip http server. The switch functionality is not affected by this error message.The problem is cosmetic.

CSCso09539 ACK not sent to 200 OK from CUE during h323 slowstart -- sip delayed med

Symptom    Incoming H323 slow start call to CME when forwarded to voicemail in CUE may result in no audio.

Conditions   This problem was observed when CME did not send ACK to 200 OK response from CUE.

Workaround   Use H323 Faststart.If incoming H323 calls need to be slow-start for video calls and calls to voicemail need to be faststart, enable H.450 call transfer feature and use two incoming dial-peers:

•One H323 dial-peer configured with "incoming called-number <ephone-dn extension range>"

and H323 slowstart using voice-class h323.

•Another H323 dial-peer configured with "incoming called-number <voicemail dn>" and

H323 faststart using voice-class h323.

CSCsq42134 JPN: 7921 XML Services are displayed as squares

Symptom    7921 directories are displayed as squires in CME Userlocale: JP environment.

Conditions   7921: 1.1.1

CME: 4.2 (IOS 12.4(11)XW7)

Locale File : CME-locale-jp_JP-4.1.0.1.tar

Workaround   There is no workaround.

CSCsq44013 View used twice with logging enabled

Symptom    The CPE does not reply to the DNS query from the client for the first try, first response is being dropped.

Conditions   This is seen on a router running 12.4T IOS image configured with Split DNS

The view is used twice rather than once.

Workaround   There is no workaround.

CSCsq64715 EM login credential could be set to stack junk in error condition

Symptom    EM login username and password may be set to random values in process stack in case the actual input from the phone is in an invalid format. And if both string picked up from the stack happen to match a username/password pair in a configured user profile, EM will login the user accidentally.

Workaround   There is no workaround.

CSCsq67163 IPSLA RTP operation crashes the router

Symptom    Scheduling of IP SLA RTP operation crashes the router.

Conditions   This problem occurs only when IPSLA RTP operation is configured and is scheduled to run.

Workaround   There is no workaround.

CSCsq74999 SCCP FXS ports connected to FAX machines lock up

Symptom    FXS that have fax/modems connected intermittently fail. Once they are in this stuck state, an incoming call to them will not ring the line, there will be no output in debug vpm sig. Outbound calls/faxes typically still work.

FXS port must be SCCP controlled. The problem is likely to occur when the pots leg is disconnected before the voip leg. If this occurs the port can go into this "stuck" state. Any subsequent calls will not ring the fax machine on this port.

Workaround   Temporary workaround is to "shut/no shut" the voice-port. This problem seems to be related to cisco fax-relay being invoked and it's interoperability with SCCP in this IOS version. Configuring:

voice service voip

fax protocol none

will prevent the problem from happening. Removing the SCCP config from the ports will prevent it from happening too.

CSCsr01058 SPLIT_DNS: Debug msg Forwarding back reply is missing

Symptom    An IOS device configured as a DNS server is vulnerable to forged answer attacks. In this type of attack, a malicious user can cause the IOS DNS server to accept a forged answer that associates a name with an IP address chosen by the malicious user. This answer ends up in the cache of the DNS server. This attack can be made more difficult by randomizing both the DNS transaction ID and the UDP source port number that the DNS server (the IOS device) uses to relay DNS queries for domain it is not authorized for.

Conditions   The above symptom is seen on a router loaded with 12.4(19.18)T image and above.

Workaround   In the case of IOS, when the IOS name server relays a query, the DNS transaction ID that is used is the original ID received from the client, and the source UDP port is always 53. To make the IOS DNS server more resilient and less vulnerable to DNS cache poisoning attacks, at the very minimum both the DNS transaction ID and the UDP source port number must be randomized. The use of bit 0x20 in DNS labels to improve transaction identity is also recommended.

This is a security issue. The problem, however, only exists for customers who are running the IOS DNS Server/Forwarder and this is presumed to not be the usual case.

CSCsr18200 busy tone issue when receiving a 183 Message

Symptom    A busy tone is not heard when a 183 message is received before a 4xx busy message.

Conditions   SIP Trunk architecture with Italtel SSW. The bug affects both 12.4(15)T and 12.4(11)XW software releases.

Workaround   A patch is required, forcing the media off when a busy message is received.

CSCsr71715 Call display missing when park or xfer HW conference call

Symptom    Caller ID and Call bubble missing when a HW conference call is parked or Xfere.

Open Caveats - Release 12.4(11)XW8

There are no open caveats in this release.

Resolved Caveats - Release 12.4(11)XW8

CSCse70333 CFwdAll erroneously reconfigured after disabling night service

Symptom    CFwdAll incorrectly appears after night service is disabled.

Conditions   CFwdAll was initially configured via softkey and un-configured via CLI. On the same dn as CFwdAll was on, night service is enabled and disabled.

Workaround   Remove CFwdAll via softkey or reload the router.

CSCsj38755 Ping Fails over ATM interface.

Symptom    Ping fails over the atm interface while applying Quality of Service.

Conditions   When we configure the qos on ATM interfaces on the back to back connected routers the ping fails.

Workaround   There is no workaround.

CSCsl26765 DTMF not detected by CUE if I/C call is txfer to ph with CFDWALL to VM

Symptom    On CUBE DTMF is not detected to stop prompt playback or record message.

Conditions   When the REMOTE incoming call is transferred to SCCP phone with CFWDALL to CUE-VM, DTMF is not detected to stop prompt playback or message recording. If original caller was LOCAL and followed the same call sequence, then there was no issue

Workaround   There is no workaround.

CSCsm23378 DTMF transcoding from rtp-nte to in-band fails for same codec

Symptom    DTMF transcoding should be done between call legs if DTMF relay is different, even if voice codecs are the same.

Conditions   If voice codecs are the same, but DTMF relay settings are different then no transcoding is done. But when voice codecs are different then transcoding is invoked, and DTMF is transcoded from rtp-nte to in-band.

Workaround   There is no workaround.

CSCsm34706 CUBE sends fixed DTMF duration and ignores received H.245 User Input

Symptom    CUBE sends a fixed 800 time units for every digit pressed (sent via RFC 2833) regardless of what it receives in the duration of a H.245 User Input field.

Conditions   In H323-SIP interworking scenario on CUBE, for DTMF conversion from 245-alphanumeric to RFC2833, regardless of the duration received in H.245 User Input field, CUBE always sends a fixed 800 ms for every digit pressed (sent via RFC 2833).

Workaround   There is no workaround.

CSCsm37093 CME 4.1after security is enabled 7970 will register with US locale.

Symptom    After security is enabled locale in the phone 7970 cannot be changed.

Conditions   Customer cannot leave security enabled and configure their locale on . Cisco 7960 and Cisco 7940 donot present the issue as they have the firmware locally stored (flash)

CSCsm64258 ephone-hunt group does NOT present calls to overlaid DNs

Symptom    When an ephone hunt-group is configured with 'present-call idle-phon', the ephone hunt-group skips the DNs which are configured as overlay.

Conditions   The problem is observed under the folowing conditions:

- ephone hunt-group is configured with 'present-call idle-phone'

- DN is configured as overlay

Workaround   Remove the 'present-call idle-phone' configuration from the ephone-hunt configuration and do not use overlaying.

CSCsm74560 phone does not look for network locale file for user defined languages

Symptom    Wireless IP phone 7920 doesnot download the 7960-tones.xml files when user defined network locale is configure.

Conditions   CME writes incomplete XML tags in the phone config file, for user defined language network locale. So phone cannot generate the query for the relevant network locale file.

Workaround   Complete the following steps to resolve the problem:

a. Along with User defined, we also need to define inbuilt network locale. For example:

–DE - Germany

– telephony- service

– network- locale DE

– create cnf- files

b. Rename the user defined file to 'germany_7960-tones.xml'.

c. Replace the file under ITS directory with the new 'germany_7960-tones.xml' (Make sure the name is the system defined name).

d. Do not run 'create cnf-file' as it will again override with the system defined parameters.

e. Reboot the 7921 wireless phone.

In case if you have issue in 'create cnf-file', then ensure to repeat all the steps mentioned above again.

CSCsm88771 CME trunk optimized calls being put on hold automatically

Symptom    Answering a trunk call transferred from another phone is automatically put on hold and cannot be resumed.

Conditions   The call originally came in on a trunk dn and is transferred to another extension on a phone sharing that trunk. Trunk optimization takes place.

Workaround   There is no workaround.

CSCsm89158 7921 does not display call park number while the call is parked

Symptom    7921 does not show the parked number when the call is parked .

Conditions   UC520W-16U-4FXO-K9 and 7921(CP7921G-1.0.3.LOADS)

Workaround   There is no workaround.

CSCso25982 SIP transfer at connect with No Audio

Symptom    No audio when one SIP extension transfers a call from PSTN side to second SIP extension.

Conditions   The call flows from PSTN to SIP Extension-A, transfer at connect to SIP Extension-B.Make a call from PSTN to DID number of SIP extension-A, extension-A answers. SIP extension-A transfer-at-connect to SIP extension-B, Extension-B answers. Extension-A completes the transfer by pressing transfer button. PSTN and Extension-B gets connected but NO AUDIO.

Workaround   There is no workaround.

CSCso26056 SIP Extension unable to transfer at alert to a PSTN number

Symptom    SIP(XOR) extension is also UNABLE to retrieve the call to PSTN-A(XEE) (hold state).

PSTN-A(XEE) remains in hold state.

Conditions   "No supplementary-service sip refer" XEE coming to CME through SIP trunk, to SIP phone XOR, consultation transfer to XTO going out through SIP trunk. The SIP trunk dial-peer has same destinationpattern as pots dial-peer, and pots dial-peer needs to have preference lower than SIP trunk dial-peer.

Workaround   Use "supplementary-service sip refer" or remove pots dial-peer with same destination pattern or make SIP trunk dial-peer preference lower than pots dial-peer.

CSCso27097 One way audio after xferring incoming SIP trunk call with transcoder

Symptom    One way audio after transfer.

Conditions   XEE SIP trunk or phone, XOR SIP Phone, XTO sccp. XEE codec is different from XOR codec, using transcoder.

Conditions   Wrong primary-phone observed after re-configure primary-dn of the ephone

Workaround   There is no workaround.

CSCso39201 ephone gets into DND mode while in Connected state

Symptom    7961 and 7941 phones going into DND mode in Connectd state.

Conditions   User getting incoming call on 7941 and 7961 phones . Since the softkeys donot update fast, if the user presses DND immediately after going into connected state then after going onhook the user phone would stuck in DnD mode.

Workaround   There is no workaround.

CSCso42145 CCME ephone name config result in called number display issue

Symptom    IP phone is displaying the calling name in placed of called name for an incoming call from PSTN.

Conditions   The problem exists in 12.4(15)XW code.
