The following new software is supported in this release:
•
CME SIP Features
MoH, Dialing, Line Updates, Presence with BLF, Provisioning New Phones
A presence service, as defined in RFC 2778 and RFC 2779, is a system for finding, retrieving, and distributing presence information from a source, called a presence entity (presentity), to an interested party called a watcher. When you configure presence in a Cisco Unified CME or Cisco Unified SRST system with a SIP WAN connection, a phone user, or watcher, can monitor the real-time status of another user at a directory number, the presentity.
http://www.cisco.com/en/US/docs/ios/voice/sip/configuration/guide/sip_cg-roadmap.html
SIP REFER
Outside the Scope of a Dialog Created with an INVITE
Out-of-dialog REFER (OOD-R) allows remote applications to establish calls by sending a REFER message to a SIP gateway without an initial INVITE.
http://www.cisco.com/en/US/docs/ios/voice/sip/configuration/guide/sip_cg-roadmap.html
VRF-Aware H.323 and SIP for Voice Gateways
VPN routing and forwarding (VRF) divides a physical router into multiple logical routers, each having its own set of interfaces and routing and forwarding tables. Adding VRF-awareness to voice gateways allows a voice gateway to exist in the same router as a customer edge (CE) or provider edge (PE) WAN router.
The VRF-Aware H.323 and SIP for Voice Gateways feature adds single voice VRF support to session-initiated protocol (SIP), H.323, and IP-to-IP gateways and to Cisco Survivable Remote Site Telephony routers. For more information, see the following link on Cisco.com:

There are no open caveats in this release.
Resolved Caveats - Cisco IOS Release 12.4(11)XJ6
CSCsh12480Cisco IOS software configured for Cisco IOS firewall Application Inspection Control (AIC) with a HTTP configured application-specific policy are vulnerable to a Denial of Service when processing a specific malformed HTTP transit packet. Successful exploitation of the vulnerability may result in a reload of the affected device.
Cisco has released free software updates that address this vulnerability.
A mitigation for this vulnerability is available. See the "Workarounds" section of the advisory for details.
This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20080924-iosfw.shtml.
CSCsg91306Multiple vulnerabilities exist in the Session Initiation Protocol (SIP) implementation in Cisco IOS that can be exploited remotely to trigger a memory leak or to cause a reload of the Cisco IOS device.
Cisco has released free software updates that address these vulnerabilities. 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.

Open Caveats - Cisco IOS Release 12.4(11)XJ4
There are no open caveats in this release.
Resolved Caveats - Cisco IOS Release 12.4(11)XJ4
Miscellaneous Caveats
•
A device running Cisco IOS software that has Internet Protocol version 6 (IPv6) enabled may be subject to a denial of service (DoS) attack. For the device to be affected by this vulnerability the device also has to have certain Internet Protocol version 4 (IPv4) User Datagram Protocol (UDP) services enabled. To exploit this vulnerability an offending IPv6 packet must be targeted to the device. Packets that are routed throughout the router can not trigger this vulnerability. Successful exploitation will prevent the interface from receiving any additional traffic. The only exception is Resource Reservation Protocol (RSVP) service, which if exploited, will cause the device to crash. Only the interface on which the vulnerability was exploited will be affected.
Cisco is providing fixed software to address this issue. There are workarounds available to mitigate the effects of the vulnerability.
This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20080326-IPv4IPv6.shtml.
•
Certain Cisco Catalyst 6500 Series and Cisco 7600 Router devices that run branches of Cisco IOS based on 12.2 can be vulnerable to a denial of service vulnerability that can prevent any traffic from entering an affected interface. For a device to be vulnerable, it must be configured for Open Shortest Path First (OSPF) Sham-Link and Multi Protocol Label Switching (MPLS) Virtual Private Networking (VPN). This vulnerability only affects Cisco Catalyst 6500 Series or Catalyst 7600 Series devices with the Supervisor Engine 32 (Sup32), Supervisor Engine 720 (Sup720) or Route Switch Processor 720 (RSP720) modules. The Supervisor 32, Supervisor 720, Supervisor 720-3B, Supervisor 720-3BXL, Route Switch Processor 720, Route Switch Processor 720-3C, and Route Switch Processor 720-3CXL are all potentially vulnerable.
OSPF and MPLS VPNs are not enabled by default.
This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20080326-queue.shtml.
•
Cisco IOS contains multiple vulnerabilities in the Data-link Switching (DLSw) feature that may result in a reload or memory leaks when processing specially crafted UDP or IP Protocol 91 packets.
Cisco has released free software updates that address these vulnerabilities. Workarounds are available to mitigate the effects of these vulnerabilities.
This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20080326-dlsw.shtml
•
A vulnerability in the Cisco implementation of Multicast Virtual Private Network (MVPN) is subject to exploitation that can allow a malicious user to create extra multicast states on the core routers or receive multicast traffic from other Multiprotocol Label Switching (MPLS) based Virtual Private Networks (VPN) by sending specially crafted messages.
Cisco has released free software updates that address this vulnerability. Workarounds that mitigate this vulnerability are available.
This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20080326-mvpn.shtml.
•
Two vulnerabilities exist in the virtual private dial-up network (VPDN) solution when Point-to-Point Tunneling Protocol (PPTP) is used in certain Cisco IOS releases prior to 12.3. PPTP is only one of the supported tunneling protocols used to tunnel PPP frames within the VPDN solution.
The first vulnerability is a memory leak that occurs as a result of PPTP session termination. The second vulnerability may consume all interface descriptor blocks on the affected device because those devices will not reuse virtual access interfaces. If these vulnerabilities are repeatedly exploited, the memory and/or interface resources of the attacked device may be depleted.
Cisco has made free software available to address these vulnerabilities for affected customers.
There are no workarounds available to mitigate the effects of these vulnerabilities.

CSCse89321: DTMF path not getting confirmed in sip media forking callSymptom There is no end-to-end DTMF path confirmation.
Workaround
CSCsf26561: User portion of Diversion header is incorrect when calling through AASymptom Tests on customer setup have revealed that PSTN to AA --> tx to SCCP phone--> CFWD to CUE/PSTN has an issue. The 302 Moved Temporarily from CME to BroadSoft has a Diversion header whose user portion is the private extension #, not the expanded DID # due to which the subsequent call fails.
Workaround
CSCsf32028: Host portion of Refer-To: header must be an Address of RecordSymptom SIP trunking environments (for example, Cbeyond) need the URIs to carry Address of Record [AOR] in many SIP headers.
Workaround
CSCsg17289: DNS-SRV issues for SIP registrationsSymptom Registrar, both the dial-peers would try to send a REGISTER request sequentially. When first Dial-peer (D1) is sending REGISTER Request, the registrar cache is empty. It first sends a DNS query (SRV). After getting the DNS Response, it updates the Registrar cache and sends the REGISTER request to Registrar R1. dns_count variable here is set to SIP_DNS_MODE.
When second dial-peer is sending REGISTER request, it finds the resolved IP address in registrar cache (R1) so it sends the REGISTER request to R1. dns_count variable here is set to SIP_NON_DNS_MODE. But both the REGISTER request fails as R1 is down.
As D1 is set to SIP_DNS_MODE, D1 would send a DNS query again with incremented dns_count to get any alternate Registrar and it gets R2. It sends REGISTER request to R2 and gets successfully registered. As D2 is set to SIP_NON_DNS_MODE, it does not retry the DNS query and simply backs off for period REG_EXPIRES/20.

Workaround
1) Disable Transcoding
(or)
2) Make sure that the Transoding and Voice Termination are on different DSP(s).
This can be performed by configuring the maximum number of transcoding sessions to a value such that it would require a multiple of 240 DSP credits.
Example 1:
In the following configuration each transcoding session (complexity=high) will require 40 DSP credits. In order to use a multiple of 240 credits, we need to set the maximum transcoding sessions to 6 (6 * 40 = 240) or any multiple of 6.
dspfarm profile 1 transcodecodec g711ulawcodec g729r8associate application SCCPRouter(conf-t)#dspfarm profile 1 transcodeRouter(config-dspfarm-profile)#maximum sessions 6Example 2:
In the following configuration each transcoding session (complexity=medium) will require 30 DSP credits. In order to use a multiple of 240 credits, we need to set the maximum transcoding sessions to 8 (8 * 30 = 240) or any multiple of 8.

Note: Each 5510 DSP has 240 Credits. This work-around cannot be implemented if the router has only one PVDM2-16 which has only one DSP.

CSCsg70221: DTMF through the hairpin of a trunk DN does not workSymptom DTMF tones are being suppressed to prevent duplicate DTMF tones from being extended to an SCCP controlled VG224 port. This problem is direct result of a fix implemented for correct CSCsf98754. The lack of DTMF prevents IVR devices from working correctly
Conditions
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 vg224. DTMF is not relayed to the end point
