When the symptom has occurred, you must reload the gateway to restore proper operation. These changes have been shown to help mitigate this problem in the majority of cases. This mechanism will trigger immediately if the impacted voice port is an analog FXO port. For other voice ports, a delay in the detection will be present and it is possible to see the symptom of this problem before the recovery code triggers.
Note that the reset mechanism will cause any active calls utilizing the DSP in question to be dropped. It is recommended if running with modules which can be impacted by this issue to upgrade to a release of software which contains the changes in CSCse Note that this output is sent at debug level and it is recommended to enable either syslog or logging buffered on the gateway.
Logging buffered on the gateway is enabled through the global command logging buffered debug as an example to set the logging buffered to use 50K bytes of processor memory for logging. The output of the log can be seen with the exec command show log. A calls B. B does an at-alert transfer to C. While C is ringing, B does a ringing pickup on C's extension. One way voice results with B being unable to hear A. Symptom No support for media flow-around in h passthru mode.
Symptom Traceback seen on the gatekeeper while deleting endpoint max-calls CLI. Symptom When trying to configure call-waiting ring on a ephone-dn x , the configuration is accepted, but cannot be seen in the configuration in show running. Symptom Router may reload due to fragmented RTP packets. This is a platform independent problem. This is not correct. Symptom Analog phones connected to the Cisco VG voice gateway can establish a three-party conference. After establishing the three-party conference, it is not sustained, the Cisco VG phone is fed with re-order tone.

New Hardware in Release The Cisco IDS network module is installed on a Cisco or a Cisco chassis to provide full-featured intrusion-protection services within the router. Only one Cisco IDS network module is supported per router and is not hot-swappable. The network module runs the latest version of the Cisco IDS software, version 4. Because the NM-CUE is a self-contained processing unit for voice applications, it adds business critical voice capabilities to the router without burdening the router processor.
Note The Fast Ethernet port and compact Flash slot, though available on the hardware, are not supported by the Cisco Unity Express network module. The Cisco IDS network module provides the ability to inspect all traffic traversing the router, to identify malicious activity, and to terminate illegitimate traffic. For instructions on accessing the IDS documentation on Cisco. It provides entry-level, IP-based voice mail and auto attendant services for small branch office environments.
Cisco Unity Express operates under Cisco CallManager Express control and is integrated into Cisco's mid-range full service branch office routers for voice and data services in a single network device. CUE offers voicemail for as few as users or up to 50 mailboxes for the small branch office of an Enterprise or for the small business with multiple branches.
For further information refer to CUE product literature and product documentation. Voice network modules convert telephone voice signals into a form that can be transmitted over an IP network. These modules have one or two slots for installing supported interface cards.
This interface supplies ringing voltage, dial tone, and so on to the station. This is the interface a standard telephone provides. The dsl operating-mode command was modified to support this new WIC. Without the NSF configuration, users have to configure their associated gateways as stand-alone H. 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.
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. This problem is direct result of a fix implemented for correct CSCsf 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 vg DTMF is not relayed to the end point.
Symptom Starting in calendar year , 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 H. 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 is over, one can for example configure:. Symptom A router may display the following message to the console repeatedly:. This is a cosmetic error. With the fix, this message will only be seen with debugs enabled. Conditions This is seen on voice routers. 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.

This reload is seen for both H and SIP calls. Workaround :There is no workaround. Symptom : After an attempt to pick up an onhold trunk dn, the call display on the ephone which puts this DN to onhold is messed up. The call can not be picked up successfully by other phone and it becomes the focus one on the phone. The connected trunk dn can not be displayed and other incoming call can not be put on hold. Conditions : There are two incoming trunk DN calls. The 1st one is answered and then the 2nd one.
The 1st one is put onhold automatically when the 2nd one is answered. After the other phone attempts to pick up the 1st call, the pickup fails and the 1st call becomes the focus one on the phone.
The softkey is displayed incorrectly. Workaround : Press the line button to resume the call onhold instead of picking it up from pickup button or fac dialing. However, this workaround can not be applied to a phone which does not have the trunk DN configured. Workaround : 1 Disable Trans coding or. This can be performed by configuring the maximum number of trans coding sessions to a value such that it would require a multiple of DSP credits. Example See this link for more information:. 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. 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 does not ring on the phone.
This problem is a direct result of a fix implemented for correct CSCsf DTMF is not relayed to the end point. Symptom : Starting in the calendar year , 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 H. 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. For example: After the summer-time period for the calendar year is over, one can configure:.
Conditions : This happens when loading a running adventerprisek9-mz. 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.
These vulnerabilities can be exploited when processing a malformed SNMPv3 message. These vulnerabilities could allow the disclosure of network information or may enable an attacker to perform configuration changes to vulnerable devices. The SNMP server is an optional service that is disabled by default. Only SNMPv3 is impacted by these vulnerabilities. Workarounds are available for mitigating the impact of the vulnerabilities described in this document. Workaround :Cisco has made free software available to address this vulnerability for affected customers.
Symptom : The minimum after-hours login timer is 5 minutes. It is too long. Customer wants to be able to deactivate the login in 1 min. Conditions : The problem is observed when after-hours call blocking is enabled. Symptom : The call display does not work correctly when attempting to pick up an onhold trunk DN.
The call cannot be picked up successfully by any other phone and it becomes the focus one on the single phone. The connected trunk DN cannot be displayed and other incoming calls cannot be put on hold. The first one is answered and then the second one.
The first one is put onhold automatically when the second one is answered. After the other phone attempts to pick up the first call, the pickup fails and the first call becomes the focus on the single phone. However, this workaround cannot be applied to a phone that does not have its trunk configured for DN.
The softkey template needs to be defined for the ringing state of an incoming call. Symptom : After a certain amount of time, some calls that have been received on a shared line and placed on hold will show From Unknown Number.
You can change the lines on the ip phone but not the lines that belong to the sidecar. If a user is logged in the Cisco CME GUI log in as user and changes the ringtype via GUI for the sidecar line and then hits save, the action will save successfully but when you go to the line again the previous ringtype still shows. Symptom : A redzone violation causes a Cisco AS to crash. Specifically, the SIP register timer expiry messages are causing this behavior. Reloading the router does not resolve the issue.
Conditions : The message below is what causes this behavior:. Symptom : Router may reload due to fragmented RTP packets. This is a platform independent problem. A calls B. B answers the call. Once the conversation is done, A hangs up. B does not go onhook. After 60 seconds, B starts hearing offhook alert howler tone. Putting B onhook now has no effect. B continues to play offhook alert for the rest of its life until the router is reloaded.
Symptom : Extension assigner will chose wrong extension if the provision-tag input is zero. Workaround : Use the ephone-tag. T crashed. The decoded tracebacks is as follows:. Conditions : This seems similar to CSCsb Workaround : Configuring no memory lite seems to alleviate the crashes. Symptom : Ephone-1 has extension 88, which is also added as a monitor line on a The Ephone-2, which is connected to the is in DND state.
Now when you try to login to a hunt-group on ephone-1, it fails because the ephone with the monitor lines is in DND state. Symptom : When an ephone hunt-group is configured with present-call idle-phone , the ephone hunt-group skips over certain members of the hunt group. Conditions : The problem is observed when members of the ephone hunt-group are monitored. Workaround : Do not monitor the members of the hunt-group.
Conditions : This happens when the phone requests for a socket that has already been used by another ephone. Symptom : The following scenario is seen:. Conditions : A simple way to reproduce this problem is as follows:. Make a call from phone on the left to a CME controlled endpoint. Press a digit button on the left phone and hold it for a long time. The user on the CME controlled endpoint on the right can hear: digit beep, silence and continuous digit beep.
If the squelching flag was set on the FXS DSP channel, the user would have heard digit beep, silence and back to voice path. This does not work for TCP sessions with a destination port that is less than , if it does not match a predefined signature on the router.
Symptom : Under heavy stress, time division backplane timeslots may be lost over time. Conditions : The symptom occurs with SS7 and more than 50 calls per second. Symptom : The show controller t1 call-counters command displays negative values for the DSO Active counter. Symptom : The called party may not be able to hear the caller.
B does an at-alert transfer to C. While C is ringing, B does a ringing pickup on C's extension. One - way voice results with B being unable to hear A. Conditions : The speed dials are configured using an ephone template, which is then applied to the affected phone. Workaround : Remove and re-apply the ephone template after the router reloads. Conditions : During call pickup, the CME sends an onhook signal to the VG port, presents a new call and immediately instructs the port to move to connected state.
During these quick steps, the voice port on the VG is erroneously reporting a hookflash. Workaround : Configure no supervisory disconnect lcfo on the Cisco VG voice port to avoid the false hookflash detection in the CME call pickup case. Conditions : With caller-id enable configured on FXO ports, the call will connect, but no audio is heard. When this occurs, the following error message can be seen at debug level:. Workaround : Disable caller-id on the voice port.
Conditions : If the Symptom : CFwdAll incorrectly appears after night service is disabled. Workaround : Remove CFwdAll via softkey or reload the router.
It would show them all in IDLE state. This problem occurs in any CME releases. Workaround : There is no work around. Symptom : An analog or digital CAS port enters a state in which inbound or outbound calls, or both, may no longer function through the port.
