Automatic configuration is not supported on IMA groups. Once a group is automatically configured, no other group can be created. All manually created groups must be deleted before creating an automatic configuration group. For details about enabling this feature, see the encap clear-channel standard and voice-class sip encap clear-channel commands in the Cisco IOS Voice Command Reference :.
Support for resetting the Expires timer upon receipt of SIP message so that when the terminating device lacks answer supervision or does not send the required SIP OK message within the timer expiry, you can enable this feature to send periodic SIP messages to reset the Expires timer and preserve the call until final response. Support for stripping off progress indicator PI from incoming Q.
Configuration of this feature determines whether an incoming Q. This behavior allows interworking with third-party SIP and H. The ITU-Y. This feature allows the Cisco Unified Border Element interwork between different dynamic payload type values across the call legs for the same codec.
No further DDTS will be committed to this branch. The migration path for this release is Affected devices would need to be configured to process SIP messages for these vulnerabilities to be exploitable.
Cisco has released free software updates that address these vulnerabilities. There are no workarounds for devices that must run SIP; however, mitigations are available to limit exposure to the vulnerabilities. Symptom After launching a flood of random IPv6 router advertisements when an interface is configured with ''ipv6 address autoconf'', removing the IPv6 configuration on the interface with ''no ipv6 address autoconf'' may cause a reload. Other system instabilities are also possible during and after the flood of random IPv6 router advertisements.
Conditions Cisco IOS is configured with ''ipv6 address autoconf''. Workaround Not using IPv6 auto-configuration may be used as a workaround. Note Cisco IOS checks for the hop limit field in incoming Neighbour Discovery messages and packets received with a hop limit not equal to are discarded. Symptom Router drops valid packets, causing SIP call to fail. Workaround There is no workaround. We can also see crashes on the Standby router if the Active interface is brought up.
Symptom A Cisco router may face ping failure between provider and customer networks. Symptom With Reverse Route Injection RRI configured with the reverse-route command, if the crypto map is applied to a multi-access interface for example, ethernet , then egress traffic may fail when the router cannot populate an ARP entry for the crypto peer address.
Conditions The symptom could occur when the upstream device does not support proxy arping. Symptom The H. Symptom Certain crafted packets may cause a memory leak in the device in very rare circumstances. Workaround Disable SIP if it is not needed.
Symptom The VTP feature in certain versions of Cisco IOS software is vulnerable to a locally exploitable buffer overflow condition and potential execution of arbitrary code. Conditions The packets must be received on a trunk enabled port, with a matching domain name and a matching VTP domain password if configured.
The first vulnerability is in the translation of Session Initiation Protocol SIP packets, the second vulnerability in the translation of H. Each advisory lists the releases that correct the vulnerability or vulnerabilities detailed in the advisory. Advisory Bundled Publication at the following link:. Repeated attempts to exploit this vulnerability could result in a sustained denial of service DoS condition. Cisco has released free software updates that address this vulnerability.
The H. There are no workarounds to mitigate these vulnerabilities other than disabling H. Two separate Cisco Security Advisories have been published to disclose the vulnerabilities that affect the Cisco Unified Communications Manager at the following locations:. Conditions When outgoing call is done using queuing-dn. Symptom Router crashes or spurious memory access can be seen. Symptom A Cisco UC crashes with memory corruption and frozen console access.
Workaround Power-cycle the router. This symptom will not occur after the image has been upgraded. Symptom Router crash when configured as mobile router with IP phone attached.

Workaround Download the IP phone firmware to a version that does not use sccp version Conditions If there are more than 42 buttons configured on the phone, some line buttons may be missing after the phone fails over to the SRST. Workaround Downgrade the phoneload to sccp v16 or lower.
Symptom The IOS messages could be observed. Conditions The symptom could happen under normal condition. Workaround Remove the split tunnel configuration. Symptom FXO ports can get stuck in offhook state. Conditions The symptom is observed when FXO ports are members of a huntgroup where the first member port is disconnected or down. The trunkgroup has max-retry configured and rapid calls are connected and disconnected using the trunkgroup.
Workaround 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. The output is different compared to the value received from the same configuration on and Workaround Use reset instead of restart. Symptom 69xx phones display toast message "From : XXXX" when it receives an incoming call for 6 seconds and then it displays the caller ID of the person.
Conditions Observed for 8. Workaround Not seen for phone firmware 8. Symptom The Update method would have two call-info headers in certain call scenarios. This would cause the caller ID information to be "unknown" when the two headers were present.
Conditions Under certain call scenarios, the Update method would have two call-info headers, one for normal remotecc info and one for security status. Workaround There is no workaround but it is not service effecting. Caller ID would be unavailable in certain instances. Symptom CME group pickup or pickup features do not work properly. Symptom A monitor phone can change the monitored dn SNR number via myphoneapp application.
Conditions Using myphoneapp on a monitoring phone can change the SNR target of a monitored dn. Symptom AnyConnect Client version 2.
AnyConnect 2. This only pertains to the 2. Workaround Any of the following workarounds may be used:. The TCP sessions could be a telnet or H. Symptom SPAG2 phone would not register. Symptom No line or speed dial buttons are shown on the fallback skinny phone. Workaround Attach side cars to the phone. Workaround Issue clear crypto isa. Symptom When using the copy ftp command to update IOS software issued on a router, it takes approximately 80 seconds before the file transfer begins.
Conditions This is seen on a or series router, but is not seen on routers in other series, such as or Conditions This symptom is observed if a WAN outage happens when more than 40 calls are in progress.

Symptom Failed to get media source address for a stream in a DO call. Conditions Failed to get media source address for a stream in a DO call with rsvp. Symptom When using mgcp dtmf-relay type nte-gw, a sniffer trace will reveal that digits are sent both in-band within the audio stream and out-of-band dtmf-relay. Because of this, double digits can be seen in Unity and MeetingPlace.
Workaround Use mgcp dtmf-relay type out-of-band. Symptom If a certificate map is changed or added to the trustpoint, the pub key cache for the peers is not cleared. This makes it possible for a client which was connected in the past to reconnect again even if its certificate was banned by the certificate map.
Conditions Only seen with IE8. Workaround IE6 can be used as a workaround. Some pages on server A automatically does a silent login to server B and gets the information required to generate reports. When using IE8 this login information does not gets properly propagated to the backend server B which results in redirection request to the login page from server B.
Symptom Tunnel sources get mixed up when tunnel interfaces are configured with serial subinterfaces as sources and the router is reloaded. Conditions The symptom occurs only after a reload or when a saved configuration is applied to the running configuration. Conditions Phone A does a call blast by calling pilot number xxxxx. All the phones start ringing till time out 60 seconds then call lands on the final phone B.
