In response to Carlos Aguinaldo. In response to Joseph W. RAM requirements, should be on the download page, per image. Here is the current RAM usage. I believe this states I have Conditions Multi node cluster and VG endpoint is registered with node other then the first node in the cluster.

Workaround Have VG endpoints register with first node. The activation of the callback is successful. What fails is when the callback destination becomes idle again and the VG endpoint gets notified ring. After the VG endpoint goes offhook, the system should automatically connect to the Callback destination.

This does not happen and VG endpoint gets silence. Symptom HLog softkey stops working. Conditions The symptom is observed under the following conditions:. Workaround Log in with the EM profile on the phone that was used to log out the huntgroup. Workaround Configure transfer-pattern with the same length of the destination number. This causes a crash in fragmentation code. Workaround Set physical interface MTU to a higher appropriate value.

Conditions IP phone part of a huntgroup and resets or power cycled when all huntgroup members logged out. Workaround Log into huntgroup Hlog and log out. When using Single Number Reach SNR feature on an ephone-dn via the ephone-dn subcommand snr , the calling party to that phone when snr is active may not hear ringback indication. Call completes without issue but the ringback may not be heard by the calling party during the alerting stage. Workaround Only known workaround is to disable the SNR feature.

Conditions CDMA modem. Workaround Use modem. Symptom Traceback observed while configuring rel1xx require CLI. Conditions Traceback can be observed after configuring rel1xx require CLI with a string of 49 characters. Symptom The system prompt may be shown during Hlog out. Conditions When an agent or all agents log out, the logout message and system message may be shown every 30 seconds. Conditions If the calls come in a PRI or FXO interface, and a user on an active call on the Octoline puts the call on hold while there is an incoming call, it will automatically answer the incoming call.

Approximately 13 seconds later the second call is dropped. If you want to put a call on hold while a new call is coming in, you must wait until the incoming call stops ringing. Symptom Lost DM connection a few minutes after bidirectional traffic started. Conditions DM configured at speed K, Smartbit configured with bytes at rate pps. Workaround Use lower speed k. Workaround Use a minimum MCR value no less than the granularity used by the router.

Conditions In the configuration mode, this always happens. Symptom A Cisco router may crash when unconfiguring IPv6 nodes. The traceback is produced after configuring the no ipv6 unicast-routing command. Conditions Problem is observed when NAT is enabled while router is configured to pass multicast traffic. Ingress interface contains analysis-module monitoring CLI command. Conditions PVC is configured with encapsulation aal5ciscoppp virtual-template 1.

Symptom Software-forced reload occurs on Cisco router. It does not come up again. This vulnerability could allow valid users to retrieve or write to any file on the device's file system, including the device's saved configuration and Cisco IOS image files, even if the CLI view attached to the user does not allow it. This configuration file may include passwords or other sensitive information. Devices that are not specifically configured to enable the Cisco IOS SCP server, or that are configured to use it but do not use role-based CLI access, are not affected by this vulnerability.

Workaround There are no workarounds available for this vulnerability apart from disabling either the SCP server or the CLI view feature if these services are not required by administrators. Workaround Have VG endpoints registered with first node. Further Problem Description : The activation of the callback is successful. Erasing the nvram filesystem will remove all configuration files!

Bad configuration memory structure -- try rewriting. It is seen only when XOR and XTO are on the same side, if they are on different sides, the call transfer goes through fine.

Symptom Memory leaks are observed in "gk process" when memory lite is disabled. Conditions When no memory lite cli is configured from the global configuration mode. Conditions Configure memory lite cli from the global configuration mode. Symptom During the firmware upgrade on E modem using microcode reload command, it is found that the modem upgrade process will stop. Conditions Any firmware upgrade to a newer version fails.

Workaround Use the laptop based watcher to upgrade. Further Problem Description : There are two issues associated with the failures:. The current enzo only uses management channel instead of data channel. The locking code interferes with the firmware upgrade code during the upgrade process, thus the upgrade fails. Observe the LED behavior.

Conditions This happens whenever the call gets connected immediately after sending Alerting response or Progress response to the caller. Symptom A call is disconnected during call resume in a sip-h call.

Conditions This symptom is observed under the following conditions:. Received call resume ReInvite. Capabilities exchanged on H leg. Sent OLC. Symptom show call active voice command may display incorrect value for codecbytes.

Symptom Outgoing of router FXO loop-start call randomly disconnected after far-end answered the call. Conditions The far-end is able to generate reverse-battery signal when called side answered the call. Also, supervisory disconnect was configured to either anytone or dualtone.

Workaround Use supervisory disconnect signal if possible. Symptom Call will be disconnected with 2 ipipgws. Conditions The media forking feature used to send stream to ASR server will fail.

Workaround This problem is introduced by cvp based media forking feature in Pi Symptom Call over the FXO loop-start cannot be established since gateway's dsp detects reverse-battery signal. Conditions The far-end is able to generate reverse-battery signal when called side is ringing. Also, supervisory disconnect is configured to either anytone or dualtone. Symptom CME version 7. Ephones register after the initial fail over to SRST and configuration is provisioned by the system, but the preferred codec used is Gulaw instead of Gr8.

However if the system is rebooted after the initial fail over, the phones register with correct codec. Workaround Reboot the system once the configuration ephone and ephone-dn is provisioned in the system.

Show voip rtp connection shows one single ip address as the local address in the cube. Conditions Occurs with single point to point or multipoint calls regardless of CTS model. This occurs only when the CTS resides in a different subnet than the interfaces on the cube and the configuration pass- thru content sdp is used in the voice service voip sip menu.

Workaround If the network architecture or policy permits use the Cisco IOS bind command to bind media to single loopback address. This address then can be advertised to connecting networks so that media is routable to the CUBE loopback.

Further Problem Description : This issue does not affect the signalling side, just the media. The command pass-thru content sdp was introduced in YB to allow flows that require a G codec such as music on hold.

Removing this command can cause disconnects on Hold and Resume. Symptom When call is disconnected, shared-line resource is not released. They cannot register with CME. Conditions When the phone is configured. The router does not even synchronize with its own internal clock. Conditions Need to have both ntp master and ntp server configured. Workaround If configuring only "ntp master" or "ntp server", the router will synchronize.

The FXS phone goes off-hook and back on-hook. The IP phone then hangs up. The next call placed will not ring the FXS port. Place the call again and the FXS will ring properly again. Call comes into shared line. IP phone answers. While the line is in-use, the analog phone goes off-hook, then back on-hook. IP phone ends the call. Conditions The issue is seen on Workaround For the first issue there is no known workaround other than placing another call to the DN after the issue is seen, or by not having the FXS phone go offhook during active IP phone calls.

Further Problem Description : Note that the second scenario is not a support solution. The call connected but audio path did not established. Conditions The call has to originate from a SIP phone thru gateway to another cme sccp endpoint and transfer back to a sccp endpoint of original cme then xfer again to another sccp endpoint within the cme.

After the cross cme call and 2 xfers, the error message shown and observed audio path failed. This results in a remote denial of service DoS condition on the affected device. Workarounds that mitigate this vulnerability are available and are documented in the workarounds section of the posted advisory. By manipulating the state of a TCP connection, an attacker could force the TCP connection to remain in a long-lived state, possibly indefinitely.

If enough TCP connections are forced into a long-lived or indefinite state, resources on a system under attack may be consumed, preventing new TCP connections from being accepted. In some cases, a system reboot may be necessary to recover normal system operation. To exploit these vulnerabilities, an attacker must be able to complete a TCP three-way handshake with a vulnerable system. This additional vulnerability was found as a result of testing the TCP state manipulation vulnerabilities.

Cisco has released free software updates for download from the Cisco website that address these vulnerabilities.

Workarounds that mitigate these vulnerabilities are available. Symptom Memory leak was found after voice stress testing on a Cisco Testing was performed for 2 hours, and call duration was 60 seconds. Symptom During 7xi2b monitoring c10k crashed at igmp-process. Note that WFQ is the default for some types of dialer interfaces.

Workaround Remove "police cir percent" from child queuing policy "cbwfq- sip". Alternate Workaround: Use a different child-policy with the same. Define a second policy-map, say "cbwfq-sip1", with the same configuration. Symptom A policy with unsupported queuing features is allowed to attach to sessions. It may cause potential issues that require a reload to recover. Further calls attempted through this port once in this state will result in the following error messages being displayed:.

Jan 8 Workaround Once in this state, the router will need to be reloaded to recover. The use of this command for stcapp controlled FXS ports does not seem to provide any benefit but can lead to the port getting into this hung state. However, when the "software mode"is used, meaning when the two member links 2 T1s are across two different PSs, then the downstream line rate drops down to 2 Megs the most. Symptom Unable to create sessions and ACLs.

Symptom SCCP phone can't act as conferencing controller. Workaround The problem doesn't exists if there is no back-to-back NAT setup. Symptom Trace back is shown when show crypto session is issued. Workaround Use commands show crypto isakmp sa and show crypto ipsec sa. Symptom Crash with the following message:. Symptom A router reloads continuously on switching off one of the redundant power supplies. Symptom Router may crash while unconfiguring "source template test" in interface configuration mode.

Symptom Router may crash and reload intermittently with TLB load or instruction fetch exception. Workaround The workaround is to temporarily remove the NTP servers from the config with:. Symptom A small memory leak may occur. The user will hear fast-busy signal when attempting to make inbound or outbound calls from or to that port.

Outbound calls to the port in this state may return a error "Previous message in-progress" in response to the CRCX. Workaround Reload the gateway to recover a port once it is in this state. Further Problem Description : Changes applied through CSCsq have been found to greatly reduce the instances of this issue from occurring. But the link on the CPE side will come up.

Symptom Unable to attach service policy to VT when bandwidth is configured in class default. Workaround Configure bandwidth in user defined class and attach to VT.

Symptom A router may crash when unconfiguring IPv6. Symptom A router may crash when reattaching a map-class or accessing the time-slots in controller mode or a router may crash when doing an OIR or flapping the peer interface. Symptom Spurious memory seen in unit test while pinging from generator to reflector. Conditions Occurs while the ping passes through router after applying the crypto map.

If the crypto map is not configured then the spurious memory will not be seen. Once this occurs there is no way to remove the HSRP config. Eventually the router will stop passing all traffic over the interface. Workaround Remove the service-policy from the xDSL interface. Symptom Router may incorrectly drop non TCP traffic. Note that this may cause higher CPU due to fragmentation and reassembly in certain tunnel environments where the command is intended to be used. Conditions I have observed this issue in Symptom When policy from mlp vaccess is removed, router crashes in queuing enqueue.

Conditions Attach queuing policy to vaccess. Remove queuing policy from vaccess. Symptom Igmp-proxy reports for some of the groups are not forwarded to the helper. This causes members not to receive the multicast traffic for those groups. Conditions The problem is seen when the igmp-proxy router is receiving UDP control traffic.
