SIP Multicast Music on Hold (MoH)
The Session Initiation Protocol (SIP) Multicast Music on Hold (MoH) feature allows the SIP gateway to subscribe to multicast music on hold when the SIP gateway is put on hold by the Cisco Unified Communications Manager.
When a VoIP phone puts a call on hold, the Cisco Unified Communications Manager asks the MoH server to stream Real-Time Transport Protocol (RTP) packets on a preconfigured multicast address. The Cisco Unified Communications Manager also sends a midcall invite with the "recv-only" attribute and multicast address to the SIP gateway. The SIP gateway subscribes to this multicast address. RTP packets are received from the MoH server and relayed by the SIP gateway to the voice interfaces.
When the VoIP phone resumes the call, the SIP-Service Provider Interface (SPI) instructs the multicast MoH server to unsubscribe from the multicast group. The IP layer drops any received multicast packets. The two-way audio channel is reestablished between the plain old telephone system (POTS) phone and the VoIP phone.
For more information on the Music on Hold features in Cisco Unified Communications Manager, see the following:
http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/admin/7_0_1/ccmcfg/b04mohas.html

http://www.cisco.com/en/US/docs/ios/voice/cminterop/configuration/guide/vc_ucm_mgcp_gw_ps6441_TSD_Products_Configuration_Guide_Chapter.html#wp1063184
The following commands are associated with the SIP Multicast Music on Hold feature:
•
•
•
•
The ccm-manager music-on-hold command enables the multicast MoH feature. The feature is turned off by default. The ccm-manager music-on-hold bind command binds the multicast music-on-hold feature to a designated interface, which decreases bandwidth usage. The debug ccm-manager music-on-hold command enables debugging. The show ccm-manager music-on-hold command displays media information.
For detailed information about the commands associated with the SIP Multicast Music on Hold feature, see the Cisco IOS Voice Command Reference:
http://www.cisco.com/en/US/docs/ios/voice/command/reference/vr_book.html
SIP SRTP Fallback to Nonsecure RTP for CUBE
The SIP SRTP Fallback to Nonsecure RTP feature enables a Cisco IOS SIP gateway to fall back from SRTP to RTP by accepting or sending an RTP/AVP(RTP) profile in response to an RTP/SAVP(SRTP) profile. This feature also allows inbound and outbound SRTP calls with nonsecure SIP signaling schemes (such as SIP URL) and provides the administrator the flexibility to configure TLS, IPsec, or any other security mechanism used in the lower layers for secure signaling of crypto attributes. This functionality was extended to the Cisco Unified Border Element (CUBE) in Cisco IOS Release 12.4(22)T.
For more information about configuring SRTP fallback and negotiation, see the srtp, srtp negotiate, and voice-class sip srtp negotiate commands in the Cisco IOS Voice Command Reference at http://www.cisco.com/en/US/docs/ios/voice/command/reference/vr_book.html.
SIT Detection and Reporting
The SIT Detection and Reporting feature provides detection of the eight U.S. special information tones (SITs) and reporting of the detected SIT with a preassigned disconnect cause code for disconnect supervision. This capability is supported for analog FXO trunk and T1/E1 channel-associated signaling (CAS) FXO loop-start. The SIT reporting complies with standard Q.850 messages in order for fax servers to uniquely identify each condition.
For more information, see the supervisory sit us command in the Cisco IOS Voice Command Reference:

http://www.cisco.com/en/US/docs/ios/qos/configuration/guide/qos_frhqf_support.html
FXO Delayed Caller ID Delivery
Before Cisco IOS Release 12.4(11)XW, Foreign Exchange Office (FXO) Caller ID in North America was delivered between the first and second ring cycles based on the Telcordia GR-30-CORE standard. FXO software was configured to wait for Caller ID delivery before initiating the call setup for the next leg. As a result, the destination endpoint did not start ringing until after 1.5 to 2 ring cycles on the FXO port.
Beginning with Cisco IOS Release 12.4(11)XW, the immediate keyword is added to the connection plar opx command. When this keyword is included in the syntax, the FXO port sets up calls immediately so that the ring-cycle discrepancy is eliminated, and the perception of the number of rings is the same for both the caller and the called party. When the Caller ID is available, it is forwarded to the called number. If the called party answers the call before the Caller ID has been forwarded, the Caller ID update will not be forwarded to the display at the called party. Refer to the Cisco IOS Voice Command Reference:
http://www.cisco.com/en/US/docs/ios/voice/command/reference/vr_book.html

G.729br8 Codec as a Superset of G.729r8 and G.729br8 Codecs
The G.729br8 Codec as a Superset of G.729r8 and G.729br8 Codecs feature enables a Cisco IOS Session Initiation Protocol (SIP) gateway to treat G.729br8 as a superset of G.729r8 (G.729 or G.729a) and G.729br8 (G.729b or G.729ab). When this feature is enabled, the Cisco IOS gateway presumes that the remote endpoint supports both G.729r8 and G.729br8 codecs and negotiates which codec to use based on the local configuration. Similarly, when the Cisco IOS SIP gateway sends a G.729br8 offer, it can accept either a G.729r8 or G.729br8 response from the remote endpoint. In both cases, the negotiated codec is downloaded to the DSP and used by both endpoints.
For more information about this feature, see the g729-annexb-all and voice-class sip g729 annexb-all commands in the Cisco IOS Voice Command Reference at http://www.cisco.com/en/US/docs/ios/voice/command/reference/vr_book.html.

PKI—CLI to Control Certificate Revocation List (CRL) Cache
The PKI—CLI to Control Certificate Revocation List (CRL) Cache feature allows the administrator to control the CRL cache size. CRLs are received by Cisco IOS software in Distinguished Encoding Rules (DER) encoded format. Because processing a DER encoded CRL uses CPU time, Cisco IOS software allows CRLs either to be stored in cache after being processed or to be decoded for the first time. Configuring the CRL cache size allows the amount of memory used for the CRL cache to be reduced (for instance, if low memory conditions exist) or to be increased for better performance (for instance, when a large number of CRLs are being processed).
The following commands were introduced or modified by this feature: crypto pki crl cache and show crypto pki crls. The crypto pki crl cache command allows the administrator to set the maximum amount of volatile memory used to cache CRLs. When the crypto pki crl cache command is configured, the show crypto pki crls command output includes information on the CRL cache size.
For detailed information about the commands that are introduced or modified by the PKI—CLI to Control Certificate Revocation List (CRL) Cache feature, see the Cisco IOS Security Command Reference:

ISDN Setup: Hash Character Within Called Party Information Element
Before Cisco IOS Release 12.4(15)T, for overlap receiving, the "sending complete" indication was obtained through the Sending Complete IE. A hash mark (#) character received in the Called Party Number IE of an Information message was notified to the application without any special consideration and simply passed "as is" for number matching.
Starting with Cisco IOS Release 12.4(15)T, the hash mark (#) within the Called Party Number IE can also be used as an indication of "sending complete" and digit collection is stopped. As a result, the hash mark is treated as a terminating character for the Called Number. Receiving this hash mark character is equivalent to receiving a Sending Complete IE.
This feature is enabled by using the following command:
isdn overlap-receiving terminating-char #

Warm Reload
The Warm Reload feature is supported on the Cisco 7200 VXR router with the NPE-G2 network processing engine. The Warm Reload feature allows users to reload their routers without reading images from storage. That is, the Cisco IOS image reboots without ROM monitor mode (ROMMON) intervention by restoring the read-write data from a previously saved copy in the RAM and by starting execution without either copying the image from flash to RAM or self-decompression of the image. Thus, the overall availability of the system improves because the time to reboot the router is significantly reduced.
X.25 Call Record
The X.25 Call Record feature makes it possible to generate a record on the source, destination, and intermediate routers for each X.25 call made through those routers. The Record also logs that Call Record onto a specified remote syslog server. This feature is disabled by default. The Record will be generated for each call that is set up and terminated successfully, each call that is set up successfully but terminates abnormally without exchange of X.25 Clear packets, and each call that fails to set up.

ADSL2/2+ Annex M support on CISCO 877-M, CISCO 1801-M, and HWIC-1ADSL-M
The Asymmetric Digital Subscriber Line (ADSL) 2/2+ Annex M feature supports routed bridge encapsulation over VC bundles on specific platforms in Cisco IOS Release 12.4(11)XJ. ADSL 2/2+ Annex M supports an upstream data rate of up to 3 Mbps and a downstream data rate of up to 24 Mbps. The increase of the Annex M (upstream) data rate is achieved by using some of the tones that were previously used in the downstream data rate in Annex A. As a result, downstream data rates are decreased in Annex M.
The ADSL training log generation command, dsl-enable-training-log, has been enhanced to specify the time when to capture a log file. This command enables the training log to record firmware debug messages.

IGMP Version 3
Support for the Internet Group Management Protocol Version 3 (IGMPv3) feature was added on the Cisco 87x and the Cisco 1800 series Integrated Services Routers (ISRs) and on EtherSwitch high-speed WAN interface cards (HWICs) and EtherSwitch network modules running on the Cisco 1841, 2800, and 3800 series ISRs.
Note
IGMPv3 provides supports for source filtering, which enables a multicast receiver host to signal to a router which groups it wants to receive multicast traffic from, and from which sources this traffic is expected. Enabling the IGMPv3 feature with IGMP snooping on Cisco ISRs provides Basic IGMPv3 Snooping Support (BISS). BISS provides constrained flooding of multicast traffic in the presence of IGMPv3 hosts. This support constrains traffic to approximately the same set of ports as regular IGMPv2 snooping does with IGMPv2 hosts. The constrained flooding only considers the destination multicast address.
In support of the IGMPv3 feature in Cisco IOS Release 12.4(15)T, the groups and count keywords were added to the show ip igmp snooping command and the output of the show ip igmp snooping command was modified to include global information about IGMP snooping groups. Use the show ip igmp snooping command with the groups keyword to display the multicast table learned by IGMP snooping for all VLANs or the show ip igmp snooping command with the groups keyword, vlan-id keyword, and vlan-id argument to display the multicast table learned by IGMP snooping for a specific VLAN. Use the show ip igmp snooping command with the groups and count keywords to display the number of multicast groups learned by IGMP snooping.
iLBC Support for SIP and H.323
The iLBC Supports for SIP and H.323 feature supports the internet Low Bitrate Codec (iLBC), a standard, high-complexity speech codec that is suitable for robust voice communication over IP. This codec is supported on both SIP and H.323.
For detailed information about this feature, see the "Dial Peer Overview" chapter and "Dial Peer Features and Configuration" chapter in Dial Peer Configuration on Voice Gateway Routers.
ISDN QEP
The ISDN QEP feature introduces the isdn layer2-flap command. When you include the isdn layer2-flap command in the ISDN configuration, the router (as a user agent) sends a RESTART or STATUS-ENQUIRY message to the remote peer when a Layer 2 flap and recovery occurs. This notification enhances the gateway's ability to gracefully recover from a Layer 2 flap or failure error condition. This graceful recovery frees gateway resources to handle future calls and to increase the call completion rate.
Use the isdn layer2-flap command with the isdn timer t309 command in your configuration. The isdn timer t309 command enables the router to hold or drop calls. The effect of using these two commands in the event of a Layer 2 flap and recovery is summarized as follows:

HWIC-1ADSL Supporting the Cisco 1841, Cisco 2800 and Cisco 3800 Platforms
This is an incremental set of Quality of Service (QoS) features that allow customers to deploy differentiated services on ADSL/ADSL2/ADSL2+ lines with the HWIC-1ADSL WAN Interface Card (WIC) on the modular Cisco 1800, 2800 and 3800 series integrated services routers. This complements the rich set of IP and ATM QoS features already supported on the platforms with an ADSL2+ interface. These additional features allow users, applications and traffic to get appropriate Service Level Agreements (SLA) as well as provide service providers with opportunities for incremental revenue generation through differentiated services.
Today, QoS is an important infrastructure component that facilitates the widespread adoption of broadband in SMB and enterprise branch office environments. In response to customer requirements and pressures, network operators and service providers are finding it critical to offer QoS features for DSL deployments. This release enables service providers with their ADSL2+ deployments with a critical set of features such as:
•
•
•
UBR+ Support
Traditionally the unspecified bit rate (UBR) service class has been used for data communications applications such as file transfer and email. UBR is a best effort service and is the lowest class of service in the ATM service class hierarchy. There are no guarantees to the actual bandwidth allowed. Therefore, UBR virtual circuits (VCs) are susceptible to a large number of cell drops or a high cell transfer delay as cells move from the source to the destination. Unspecified bit rate plus (UBR+) is a special ATM service class designed to provide a minimum bandwidth guarantee. With UBR+, the ADSL ATM interface has the ability to assure a minimum as well as maximum bandwidth on the line. As a result, the user can have some assurance of a range of bandwidth values necessary for QoS.
Multiqueue Support
Today's access networks are increasingly carrying voice, video and data traffic over physical lines. Thus it is crucial for the access routers to honor latency, jitter and other requirements for delay sensitive traffic. The multiqueue feature provides for 2 separate hardware queues on the access router for every permanent virtual circuit (PVC) in the system, one to carry high priority and the other to carry regular (data) traffic.
ATM Oversubscription for DSL
Today, more and more business customers demand high availability in the networks. In many cases they use primary as well as secondary WAN interfaces for 24x7 connectivity. In ADSL networks, loss of connectivity may arise when the ADSL line is down or when the PVC is non-functional because of equipment failure in core networks. In order to overcome the challenges posed by the latter case, service providers are increasingly deploying primary and backup PVCs on the ADSL interface. However with a backup PVC, the configurable bandwidth requirement of all the PVCs in the system may be greater than the ADSL line rate. This may cause PVCs that need minimum bandwidth guarantees to be downgraded to a UBR class of service. The ATM Oversubscription feature allows the operator to configure oversubscription on the ADSL interface up to a defined bandwidth. The operator can configure variable bit rate (VBR) and unspecified bit rate plus (UBR+) service classes for PVC connections with a sum of sustainable cell rates (SCRs) greater than the line rate. Resource limitations on Cisco xDSL interfaces require a way to configure bandwidth oversubscription up to a defined bandwidth (a finite oversubscription of bandwidth by a factor of 2).

Smartports on ISR EtherSwitch
Smartports macros are supported in EtherSwitch network modules that are installed in a Cisco Integrated Service Router (ISR). The EtherSwitch network module is a high-density voice network module that provides Layer 2 switching across Ethernet ports. Smartports macros, also known as role-based macros, are sequences of CLI commands that enable features and configure settings on a switch port. Because they support an easily repeatable mechanism for enabling features and configuring settings, Smartports macros provide a simple method for configuring switch ports based on the location of the switch within the network. Smartports macros are also useful for customizing specific switch port configurations for mass deployment.
When you apply a Smartports macro on an EtherSwitch module or interface, the CLI commands within the macro are configured both on the target interface (or interfaces) and on any existing module or interface configurations. The new commands are added to the interface and are saved in the running configuration file.
Six default Smartports macros are provided as part of the Cisco IOS software. Each of these macros configures features suitable for connecting a switch port to a specific type of device:
•
•
•
•
•
•
Although you cannot modify the default Smartports macros, you can create any number of customized Smartports macros. Customized macros can be tailored to define alternative or customized switch port configuration profiles.

VLAN.DAT to NVGEN
The VLAN.DAT to NVGEN feature enables you to save VLAN database configuration information for EtherSwitch network modules installed in a Cisco Integrated Service Router (ISR) in a single configuration file. The EtherSwitch network module is a high-density voice network module that provides Layer 2 switching across Ethernet ports. This feature enables network administrators of modular switches that contain VLAN information to back up the switch system in a single configuration file stored in NVRAM, rather than with multiple configuration files. With versions of Cisco IOS software prior to Release 12.4(11)T, VLAN database configuration information is stored in the compact flash memory in a VLAN.dat file and is not included in the startup configuration file. To save and restore a complete backup of a modular switch system with versions of Cisco IOS software prior to Release 12.4(11)T, you must manage both the startup configuration and VLAN.dat files.
With the introduction of this feature, an ISR EtherSwitch that uses the VLAN.DAT to NVGEN feature is in VTP server mode by default. When the switch is in VTP server mode, you can save the VLAN information to the VLAN.dat file only. To save the VLAN database configuration information to NVRAM instead, first use the vtp transparent global configuration command to set the device to the transparent VTP device mode; configuring the switch as VTP transparent disables VLAN Trunking Protocol (VTP) from the VTP management domain but does not remove the domain from the switch. Then configure VLAN information in the new config-vlan command mode. The VLAN database configuration information will be included in the startup configuration file that is generated by the nonvolatile generation (NVGEN) process invoked by the copy running-config command.

FRF 1.2 Annex A Support
The FRF 1.2 Annex A Support feature is also called Local Management Interface (LMI) segmentation. It supports an enhancement to the Frame Relay LMI protocol by which LMI full status messages are segmented because of MTU constraints or large numbers of permanent virtual circuits (PVCs). This feature is useful when the maximum MTU size is insufficient to accommodate the large number of PVCs on the link. During Frame Relay internetworking with other Layer 2 protocols, the MTUs on each interface must match. In software that does not have the FRF 1.2 Annex A Support feature, you cannot change the MTU size on the Frame Relay side and place all PVC data in one LMI packet. The FRF 1.2 Annex A Support feature removes this limitation.
The FRF 1.2 Annex A standard adds a new message type "Full status continued" to an LMI packet. When a DCE determines that it cannot fit all PVCs into one packet (enforced by the MTU size), the message type is set to "Full status continued." The DTE responds immediately to "Full status continued" messages that are sent to this packet instead of waiting for the T391 timer to expire. The DCE sends the remaining PVCs in one or more "Full status continued" messages until all the remaining PVCs can fit into one message. At this point, a normal "Full status" message is sent.
If the DTE receives a "Full status" or "Full status continued" STATUS message in response to a "Full status continued" STATUS ENQUIRY message, this exchange indicates a lower-valued data-link connection identifier (DLCI) than the prior "Full status continued" STATUS message (and is considered to be an error event), and PVC information elements (IEs) are not processed. The next time the T391 timer expires, the "Full status" STATUS ENQUIRY procedure is reinitiated.
This feature follows the FRF 1.2 implementation agreement and allows Cisco IOS software to be compliant with the FRF 1.2 standard. The implementation is platform-independent and applies to all platforms running Cisco IOS software that support Frame Relay. This feature interoperates only with existing Cisco IOS software releases in which all PVCs can be reported in one packet. A router running the new functionality must be able to interoperate with routers that are running existing Cisco IOS software releases and with routers that support the new functionality using the continuation status request and reply frames. Only LMI types Q.933A and ANSI support the FRF 1.2 Annex A standard.
You can track "Full status continued" packets by using the debug frame-relay lmi command in privileged EXEC mode. An extra field, 04, has been added to the display output (the last row in the following example indicates where in the report to look for this field):
17:42:39: Serial1(out): StEnq, myseq 126, yourseen 125, DTE up17:42:39: datagramstart = 0x40058DA4, datagramsize = 1317:42:39: FR encap = 0x0001030817:42:39: 00 75 51 01 04 53 02 7E 7DThe string segment "active/inactive" in the display of the show interface commands indicates whether the FRF 1.2 Annex A standard is triggered. The report indicates active when routers receive the "Full status continued" message; otherwise, the report indicates inactive.
