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 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. This is just the labeling and does not affect functionality. Conditions This is seen with the B models of the wireless routers running This issue does not affect functionality. Conditions CME running On the with IOS 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 q 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. Symptom Modem connection is still active on exit.
Conditions After "exit" from modem session. Symptom dtmf stop working if using connection plar opx immediate on fxo port. Conditions Cu is running XW on uc Workaround Don't use "immediate" option for the "connection plar opx". 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. Conditions Phone call has to be from remote phone. 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.
Symptom After a reboot of the router, or sometimes during normal operation, an IPsec tunnel fails to initiate. Conditions The router is running 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 Instead it sends a BYE and the call gets disconnected. Workaround To work around this problem, reload the device manually after restoring the configuration file. This vulnerability affects several Cisco products that have support for wired or wireless EAP implementations. Disable MOH from flash that implies tone on hold or beep on hold. Debug ephone detail will show the following error:.
Workaround Reboot the phone. Symptom DTMF levels are 0. Conditions This causes under normal conditions. Workaround Setting the cptone on the voice port to Singapore cures the problem. 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:. Conditions The problem can be seen for every call. 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 Resetting VC resolve issue. 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. Workaround Configure permitted host statements successively and do the same for permitted networks.
Symptom A Cisco router may crash due to a bus error. 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. 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. Symptom Cisco IP Phone placed on hold hears fast busy instead of tone-on-hold.
Workaround This behavior was introduced in 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. Symptom The Cisco Embedded Event Manager may hang and tie up virtual terminal vty lines if the devices host name is longer than 20 characters.
Conditions The device has a hostname configured that is longer than 20 characters. Workaround Use a hostname less than 20 characters.
These vulnerabilities pertain to the following protocols or features:. Cisco has made free software available to address these vulnerabilities for affected customers. Fixed Cisco IOS software listed in the Software Versions and Fixes section contains fixes for all vulnerabilities mentioned 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. Conditions This happens under any normal conditions. If the phones are configured as SCCP endpoints, the phones will not register. Workaround This issue has been resolved.
The solution is available in the release of CME 4. Conditions This symptom is observed on a Cisco router that is "fresh out of the box" and affects the following routers:. Workaround For extensive information and a workaround, see the following Field Notice:. Overall performance of the device can deteriorate to some extent.
Solution The only way to rectify this situation is to reboot the device. Cisco recommends upgrading to a fixed software release. Symptom IP phone trying to create an ad-hoc conference is dropped when pressing "Conf" softkey the second time. Conditions Must be using hardware conferencing in CME 4. The IP phone must receive a call first on on overlaid button. This initial call must come in on any DN besides the first DN configured in the "button" command in ephone configuration.
A caller call a person "A". Person "A" answer the call. Person "A" is monitored by the person "B". The person "B" see on his phone that the person "A" has received a call. Also person "B" calls person "A" using the monitor button.
Person "A" answers the call, putting the first caller on hold. Person "A" uses the conference softkey "Confirm". The message "Select Line" appears without any effect. Devices running Cisco IOS versions This memory leak is not seen until we load a tcdf file. This issue is specific to the PI11 codebase. Conditions ipbasek9 is the only package enabled. Conditions Only for SBC proxy address configuration and only if either of the addresses is zero.
Symptom cme on cadvipservicesk9-mz. For example:. Symptom Queue-limit configured in ms is not displayed in show policy-map int output. Conditions This happens in a scenario where queue-limit is configured in ms in class-default. Symptom Chunk memory leaked while configuring the ip nat pool. Conditions While configuring the pool with subnet mask smaller than required length for the start and end ip address. Symptom Using the command default dest-ipaddr for udp-echo, udp-jitter, and tcp-connect causes a device to crash.
Conditions The symptom is observed with the command default dest-ipaddr. Workaround Do not use the command default dest-ipaddr. This sets the address to 0. Symptom A Cisco router may crash when configuring the object id in config-event-objlist subconfiguration mode. Conditions This symptom is observed when entering the cns config notify command. Symptom NIOS watchdog timer times out. Conditions This symptom is observed when an MC modem is power-cycled.
Workaround Reload the router. Workaround Once the phone state changes, it will reflect the real state to the blf sessions. Symptom The CME does not process the incoming sip message.
Conditions Call forward scenario where incoming sip messsage is received. Workaround Configure : voice service voip no notify redirect ip2ip. The IOS version is Workaround Use earlier IOS such as Remove voice source-group configuration. Conditions Happens when the CME is loaded with Workaround Call will flow through. Symptom User can not press the button configured as trunk-dn monitor to pick up the parked call.
Or user cannot press the button configured as M button to speed-dial. Conditions Pressing the monitor button, no OP. Symptom Not able to configure call-forward system redirecting-expanded. Conditions Not able to configure call-forward system redirecting-expanded on a router. Symptom After a license upgrade from 48 to 64 user license on a UC, the Cisco series phone registration fails with the following errors in debug ephone register output:. The problem only occurs when the ephone tag value for this phone registration is 56 or higher.
Workaround Use an ephone tag that is of lower numerical value. Ephone 55 or lower will work. Symptom When shared line has 2 calls, and these 2 calls disconnect at the same time, the port might hang. Symptom Build failure is happening for platform images. Conditions FXO ports are members of a huntgroup where the first member port is disconnected or down. Unconfigure max-retry. Under each port, configure "timeouts power-denial 0" so that disconnected ports are moved to offhook state and will not be hunted.
Symptom CPU profiling under interrupts is not reliable. Symptom A Cisco router reloads when trying to connect to irc. Conditions The symptom is observed only in the first 36 hours following a reload. Workaround Do not connect to irc. Conditions This happens when the CLI's parser chain was moved, hence missing them on the platforms.
Need to ensure the parser chain is implemented as platform independent. Symptom Consult transfer with third party sip endpoints results in one way audio when the third party endpoint has delayed response to resume request which includes change in rtp stream parameters i. Conditions sip supplementary services refer is disabled. Symptom IP connectivity fails for the interface following extended pings from FastEthernet interface. The show interface command will indicate that the output queue is wedged:.
No indication at this time that this is specific to these images. This problem has not yet been seen on an interface in full duplex mode. Symptom Router reloads with a bus error and no tracebacks. The installed IOS version is any Workaround There is no known workaround available. Subsequent calls through that same channel continue to fail with "resource unavailable" cause value equal to 47 even after DSP resources have been made available to handle the call.
The call must first fail with a legitimate DSP allocation error. Any call made through the same channel as the failed call will also fail. DSP allocation failures on gateway can be checked through the use of the exec command show voice dsp group all. The last line of the show command output includes a counter for "DSP resource allocation failure". This issue can also be seen in some cases upon bootup. When a gateway is reloaded, system resources will come up with a slightly different timing.
If, for example, a PRI interface comes up before the DSP resources have fully initialized, there may be a similar failure. Workaround The workarounds are as follows:. When the gateway comes back up, take the voice-port out of shutdown. An increase of almost 10 percent in CPU utilization is observed with every voice call. Workaround Remove the AIM compression card from the motherboard.
Outbound calls to the SIP provider have one-way audio. The internal IP phone can hear the remote party, but the remote party cannot hear the internal IP phone. Conditions TNP phones with firmware 8. Workaround Wait for about a minute, and the port will automatically recover back to registered.
Symptom A call from a night hunt forwarded to BACD dial by an extension to an ephone call forwarding no answer to voicemail goes to the night hunt number and not the last redirected number. The packets will appear as output drops on the ATM interface statistics. Under the PVC level, there are no drops.
The ATM interface s need to be bridge-group configured. The bridge-group is in forwarding mode. Symptom The call-waiting tone will not be generated and the caller ID will not be displayed for the second call to a phone connected to a FXS port. Configuring either caller-id enable or caller-id enable type 2 on the FXS voice port will trigger this issue. Workaround Configuring caller-id enable type 1 under the voice port will provide call-waiting tone. However, caller-id will not be provided for the second call.
This timer dictates how long a T1 CAS, wink-start endpoint must remain offhook before completing a wink. Thanks for following! As follower of the group you will receive email notifications of events in the group. Bigger groups, bigger fun. It looks like I've been quite unfortunate in my selection of router from the looks of it. The only viable update I can find for the specification I have is cnm-advipservicesk9-mz. I'm unable to find it anywhere. Does anyone know if I go via Cisco's security vulnerability policy if I can get that way?
