Feature Set Tables
The Cisco IOS software is packaged in feature sets consisting of software images—depending on the platform. Each feature set contains a specific set of Cisco IOS features.
Cisco IOS Release 12.2(11) YT2 supports the same feature sets as Cisco IOS Release 12.2, but Cisco IOS Release 12.2(11) YT2 can include new features supported by the Cisco 2600 series routers.
Caution
Cisco IOS images with strong encryption (including, but not limited to, 168-bit Triple Data Encryption Standard [3DES] data encryption feature sets) are subject to United States government export controls and have limited distribution. Strong encryption images to be installed outside the United States are likely to require an export license. Customer orders may be denied or subject to delay because of United States government regulations. When applicable, purchaser and user must obtain local import and use authorizations for all encryption strengths. Please contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com.
Table 3 and Table 4 lists the features and feature sets supported by the Cisco 2600 series routers in Cisco IOS Release 12.2(11)YT and uses the following conventions:
•Yes—The feature is supported in the software image.
•No—The feature is not supported in the software image.
•In—The number in the "In" column indicates the Cisco IOS release in which the feature was introduced. For example, "12.2(11)YT1" means a feature was introduced in Cisco IOS Release 12.2(11) YT2. If a cell in this column is empty, the feature was included in the initial base release.
Note These release notes are not cumulative and list only features that are new to Cisco IOS Release 12.2(11) YT1. The parent release for Cisco IOS Release 12.2(11) YT1 is Cisco IOS Release 12.2(11)T. For information about inherited features, refer to Cisco.com or Cisco Feature Navigator.

New and Changed Information
The following sections list the new hardware and software features supported by the Cisco 2600 series routers for Cisco IOS Release 12.2(11) YT2.
New Hardware and Software Features in Cisco IOS Release 12.2(11)YT2
No new hardware or software features are supported in Cisco IOS Release 12.2(11)YT2.
New Hardware Features in Cisco IOS Release 12.2(11)YT1
There are no new hardware features supported by the Cisco 2600 series routers in Cisco IOS Release 12.2(11)YT1.
New Software Features in Cisco IOS Release 12.2(11)YT1
The following new software features are supported by the Cisco 2600 series routers for Cisco IOS Release 12.2(11)YT1:
Cisco IOS Telephony Service V2.1 Updates
Cisco IOS Release 12.2(11)YT1 introduces improvements to phone rebooting commands and an updated script for the H.450 transfer and forward application.
After you update information for a phone that is associated with a Cisco IOS Telephony Service (ITS) router, the phone must be rebooted for the new information to take effect. In Cisco IOS Release 12.2(11)YT1, the reset command has been modified to allow the sequential reboot of the ITS phones. Using a sequential reboot minimizes the risk of conflict which can occur when multiple phones attempt to access changed ITS configuration information through TFTP. In addition, the restart command has been added to support quick phone rebooting for use when only the line and speed-dial configuration for a phone is changed.
The tool command language (TCL) script that controls H.450 applications has been updated in the current release and is named app-h450-transfer.2.0.0.2.tcl. You can continue to use the previous script, called app-h450-transfer.2.0.0.1.tcl, with Cisco IOS Release 12.2(11)YT1, but you cannot use the new app-h450-transfer.2.0.0.2.tcl script with a release of Cisco IOS software that is earlier than Cisco IOS Release 12.2(11)YT1.
For more information, refer to Cisco IOS Telephony Service V2.1:New Features for Cisco IOS Release 12.2(11)YT at the following URL:

Platforms supported: Cisco 2691
Clear Channel T3/E3 with Integrated CSU/DSU
Non-channelized (Clear Channel) T3/E3 service is delivered as a T3/E3 pipe with the bandwidth being 28x24x64k for T3 or 16x32x64k for E3. Clear Channel T3/E3 service is generally used in point-to-point applications (one customer sending data to one remote site). Any subdivision of bandwidth is performed at each customer site rather than at the central office.
Platforms supported: Cisco 2650XM, Cisco 2651XM, and Cisco 2691.
For more information, refer to the document at the following URL:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122limit/122y/122yt/122yt11/ft_te3nm.htm
Content Engine Network Module for Caching and Content Delivery
The Content Engine (CE) Network Module for Caching and Content Delivery offers the ability to integrate the features of Cisco Application and Content Networking System (ACNS) software into branch office platforms. The CE network module combines the Content Caching, Content Filtering, and Content Delivery features of ACNS with robust branch office routing and is supported on Cisco 2600 series, Cisco 3600 series, and Cisco 3700 series routers. The network module requires the use of ACNS 4.2 software.
The CE network module can operate as a standalone cache or in an integrated enterprise content delivery network (E-CDN) environment. As one element of an E-CDN, the CE network module can be deployed with a combination of other content engines, content routers, content services switches, and content distribution managers to create a complete content delivery network system.
Platforms supported: Cisco 2610 to Cisco 2613, Cisco 2620, Cisco 2621, Cisco 2650, Cisco 2651, Cisco 2610XM, Cisco 2611XM, Cisco 2620XM, Cisco 2621XM, Cisco 2650XM, Cisco 2651XM, and Cisco 2691.
For more information, refer to the document at the following URL:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122limit/122y/122yt/122yt11/ft_1cenm.htm
Gigabit Ethernet Network Module
The Gigabit Ethernet network module provides gigabit connectivity. The throughput of the interface depends on the platform. The network module has one GBIC slot to carry any standard copper or optical Cisco GBIC, including CWDM. The GE network module optimizes the performance for branch office customers by offering a high-speed uplink to both existing and new LAN or WAN environments. The extended reach of the provided fiber connectivity allows customers the option of interconnecting branch offices with Gigabit Ethernet and avoids expensive leased serial lines. Metro Area Service Providers now have additional options when connecting their customers in branch offices to MANs.
Platforms supported: Cisco 2691.

CSCdy48624 |
Caller ID is not updated on XTO to XEEs ID once XOR commit transfer Symptom: After a call is transferred, transferee phone is connected to the transfer-to phone; however, the display on transferee phone shows it is connected to the transferrer phone instead. Respectively after consultation transfer, the transfer-to phone shows it is connected to the transferrer phone instead of the transferee phone. Conditions: The wrong display on the transferee phone happens on both blind transfer and consultation transfer. The wrong display on the transfer-to phone happens on consultation transfer. Workaround: There is no workaround. |
12.2(11)YT1 |
CSCdy63251 |
IVR TCL fail to send gtd Symptom: A voice over IP (VOIP) gateway running with Interactive Voice Response (IVR) application cannot pass Generic Transparency Descriptor (GTD) information to the next gateway. Conditions: This happens on setup message only. Workaround: There is no workaround. |
12.2(11)YT1 |
CSCdz03521 |
Phones TFTP access contention causes locale changes to remain in EN Symptom: When more that one IP phone attempts to access configuration files from ITS at the same time by using the Cisco IOS TFTP server, the second phone fails to gain access and may report an error on the phone display and in the status messages display (accessed through the Settings key on the phone). In most cases the phone will continue to operate by using the configuration information that was stored in the phone the last time that the phone was rebooted. Only if the configuration information has changed, for example if the Services URL is modified, or the phone language or local changed, or the phone firmware version is changed, will the TFTP access failure cause a problem. The phone may end up misconfigured if it is able to access some but not all modified configuration files. Workaround: Reset any phone that reports a TFTP error again. When making global changes to the configuration that affect multiple phones, reset the phones one at a time and wait until the phone reregistration is completed before commencing the reset sequence for the next phone. |

raw message lost when h450 information exists in setup request Symptom: Raw message may fail to be sent from a Voice Over IP (VoIP) gateway to another gateway across an IP link. Conditions: This happens only on the setup message, and when the raw message coexists with an H.450 message. Workaround: There is no workaround. |

Traceback at CallSetupCleanup for redirect at alert Symptom: A Cisco IOS voice gateway may show traceback messages when using the H450 call transfer and call forward TCL application. Conditions: This may happen when the Cisco IOS gateway has the transferrer party committing the transfer while the transfer-to party is still alerting. Workaround: There is no workaround. |

no dial tone after transfer during alerting to an FXS phone. When performing a transfer with consultation, if a call transfer is made to an analog FXS phone (or any call transfer that provides in-band alerting) and the transfer is committed during the alerting stage (while the consulted phone is ringing), then after the transfer is completed, if the phone attempts to make any outgoing calls, the phone will not get dial-tone. The call can still be made; however, the user does not hear dial tone. This situation continues until a call is made to or from the phone that results in a call actually being connected, or the phone is rebooted. When transfers to other local IP phones are attempted (which provide out-of-band alerting), this problem does not occur. Workaround: Do not use transfer with consultation. Configure the system so that all call transfers are committed as blind transfers. Alternatively, do not attempt call transfers to destinations that provide in-band alerting. |

LBDN converts in-band alerting state to out-of-band alerting Symptom: An originating Foreign Exchange Station (FXS) phone hears a ringback tone instead of a busy tone. Conditions This symptom is observed when a call comes in from an FXS phone on Gateway 1 or Gateway 2. The call comes into Gateway 2 through a pair of loopback-directory numbers (loopback-dns) and is forwarded on Call Forward No Answer (CFNA)/call forward busy (CFB) to a public switched telephone network (PSTN)/PRI gateway. The PSTN gateway phone is busy; hence, a disconnect tone is sent to the originating side in the form of PI value 8. Gateway 2 receives in-band alerting. The loopback-directory number (loopback-dn) pair converts in-band alerting to out-of-band alerting. Workaround There is no workaround. |

CFNA fails(ls_007) in 2GW scen, mainly when XOR(reroutemode)REDIRECT Symptom: A TCL Interactive Voice Response (IVR) script may not receive an ev_setup_done event after the call is forwarded. Conditions: This happens on a diverting gateway when call forwarding end before the outgoing leg is disconnected. Workaround There is no workaround. |

Abnormal disconnect of XEE-XTO call in 2 gateway consult transfer Symptom: A consultation transfer is prematurely disconnected shortly after it is committed. Conditions: Transferrer and transfer-to parties are on different gateways, and on the transfer- to gateway, the leg towards transferrer is disconnected before the new conference between transferee and transferrer-to leg is established. Workaround: There is no workaround. |

One way speech path after one gateway fullblind transfer Symptom: In a Voice Over IP (VoIP) gateway running Interactive Voice Response (IVR), an IP phone may hear a one-way voice after a blind transfer. Conditions: Both transferee and transfer-to parties are IP phones connected to the same gateway. The blind transfer is initiated by the calling party. Workaround: There is no workaround. |

Loopback-dn hangs when call gets disconnected Symptom: Calls are made from PSTN to IP phone of ITS through a pair of LBDN. A call is transferred to another IP phone over PSTN. When the terminate side disconnects by sending an inband disconnect tone to remote end, the IP phone goes off-hook, but the LBDN stays hung, making it unusable. Workaround: Reload the router. |

Double-Alert indication send to LBDN instead of single-alert Symptom: Calls are made from PSTN to IP phone of ITS through a pair of LBDN. A call is transferred to another IP phone over PSTN. The remote IP phone is busy. A double alert indication is sent instead of a single alert. Workaround: There is no workaround. |

Local Consult is broken Symptom: When ITS is configured to perform a call transfer by using the local-consult option, the call transfer is committed during alerting of the transfer-to IP phone and the transfer-to IP phone attempts to answer the (consultation) call at the instant that the transfer is committed, the transferred call may be dropped. Workaround: Wait for the consultation call to be answered before transferring the call, or use an alternate call transfer mode. |

one way voice path with loopback-dn if RTP header compression enable Symptom: A one-way voice path is heard if the RTP header compression is enabled for the external VoIP call segment, and the call is routed through a loopback-dn to a local ITS IP phone. To get the one-way voice path, the call must be transferred by using the app-h450-transfer.tcl script to support transfer with consultation. The transfer must be committed during alerting of the transfer-to local IP phone. If the transfer is committed after the local transfer-to IP phone has answered the consultation call, the problem is not seen. Workaround: Disable the RTP header compression. |

IVR leg setup returns ls_009 instead of ls_004 for disc cause 0x1C Symptom: When a call setup fails due to reason 0x1C (Invalid number format), an voice interactive response (IVR) application may return status ls_009 (Destination disconnect) instead of ls_004 (Invalid number). Workaround: There is no workaround. |

Symptom: The delay required in auto-negotiation for copper GigaBit Interface Convertor (GBIC), may flap the GE interface ONCE when the interface with copper GBIC is re-configured. This may also cause the EtherChannel to flap if the copper GBIC interface is a member of the EtherChannel. Workaround: Do not use the GE interface with copper GBIC as a member of EtherChannel. |

Symptom: You cannot forward a call that was transferred. Conditions: A Cisco IP phone on a voice over IP (VoIP) gateway has call forwarding configured, but the call-forward pattern is not set or it does not match the forwarding number. If the incoming call to the local IP phone is a transferred call, then the call forwarding initiated by the phone fails. Workaround: Set the call-forwarding pattern correctly under telephony-service on the local gateway, so that the pattern matches the forwarding number. |
