New Software Features in Cisco IOS Release 12.1(5) XM2
The following new software features are supported by the Cisco AS5400 for Cisco IOS Release 12.1(5) XM2.
Call Admission Control Based on CPU Utilization
The Call Admission Control for CPU Utilization feature permits Cisco access servers, and Cisco universal gateways to deny incoming calls exceeding a preconfigured threshold, permitting the selection of a system CPU load level value. This feature helps ensure the quality of service of existing calls and reliability of system processes by preventing system overload caused by excessive incoming calls. The feature rejects new digital calls (PRI, CAS, and ISDN), with minor disruption to system users. When the preconfigured call denial threshold is reached, subsequent calls cannot get through and the caller hears a busy tone.
For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5800/sw_conf/ios_122/dt61294.htm.
Cisco H.235 Accounting and Security Enhancements for Cisco Gateways
The Cisco H.323 gateway now supports the use of CryptoH323Tokens for authentication. The CryptoH323Token is defined in H.225 Version 2 and is used in a "password-with-hashing" security scheme as described in section 10.3.3 of the H.235 specification.
For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5800/sw_conf/ios_122/pul0242x.htm.
Cisco H.323 Multizone Enhancements
This feature enables the Cisco gateway to provide information to the gatekeeper with the use of additional fields in the RAS (registration, admission, and status) messages.
For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5400/sw_conf/ios_121/pull0244.htm.
Cisco H.323 Version 2 Phase 2
Cisco H.323 Version 2 Phase 2 upgrades Cisco IOS software by adding several optional features of the H.323 Version 2 specification and facilitates customized extensions to the Cisco Gatekeeper.
For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5400/121/121x/pullv2p2.htm
Configurable Timers in H.225
The H.323 Support for Virtual Interfaces feature allows users to configure the H.225 TCP connection timeout value for all out-going call attempts (on a per VoIP dial-peer basis).
For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5400/sw_conf/ios_121/pulcfgtm.htm.
Dial Peer Enhancements
The following are the new dial-peer enhancements supported:
•
Beginning in this release, additional dial string symbols are supported that you use with the destination-pattern dial-peer configuration command to establish the digit pattern.
•
To match on a number type for a dial peer call leg, the numbering-type command is used in dial-peer configuration mode. Number-type matching is supported on Plain Old Telephone Service (POTS), VoIP, VoFR, and VoATM dial peers.
•
When a called number is received and matched to a POTS dial peer, the matched digits are stripped and the remaining digits are forwarded to the voice interface. A new command called digit-strip makes this default behavior an option. The digit-strip option is supported on POTS dial peers only.
•
When configuring your dial peers, you are provided with an option called the translation rule. This rule applies a translation rule to a calling party number (Automatic Number Identification [ANI]) or a called party number (Dial Number Information Service [DNIS]) for both incoming and outgoing calls within Cisco H.323 voice-enabled gateways. Also, the rule allows translation of the type of number.
For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5400/sw_conf/ios_121/puldt662.htm.
Ecosystem Gatekeeper Interoperability Enhancements
The H.323 Support for Virtual Interfaces feature supplements the existing support for alternate gatekeepers and adds support for the alternate gatekeeper field (altGKInfo) to the gatekeeper rejection (GRJ) and registration rejection (RRJ) messages. This allows a gateway to move between gatekeepers during the gatekeeper request (GRQ) and registration request (RRQ) phases.
For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5400/sw_conf/ios_121/pulclrnt.htm.
Ecosystem Gatekeeper Interoperability Enhancements, Phase 2
The H.323 Support for Virtual Interfaces feature supplements the existing support for alternate gatekeepers and adds support for the alternate gatekeeper field (altGKInfo) to the admission rejection (ARJ). This allows a gateway to move between gatekeepers during the admission request (ARQ) phase.
For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5400/sw_conf/ios_121/pulgkarj.htm.
Feature Group D Support
This feature extends support for Feature Group D signaling on Cisco platforms. Feature Group D service is a trunk side connection that enables telephone customers to choose their long distance network and use the same number of digits no matter which carrier they use. Routers interface with interexchange carriers using Feature Group D to support voice traffic in the carrier environment.
For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5400/sw_conf/ios_121/pulhdvfg.htm.
Gateway Support for Alternate Gatekeeper
The Alternate Gatekeeper feature provides redundancy for a gatekeeper in a system where gatekeepers are used. This enhancement allows a gateway to use up to two alternate gatekeepers as a backup in the case of a primary gatekeeper failure.
For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5400/sw_conf/ios_121/pulaltgk.htm.
Gateway-to-Gatekeeper Billing Redundancy
The Gateway-to-Gatekeeper Billing Redundancy feature enhances the accounting capabilities of the Cisco H.323 Gateway and provides support for Vocaltec Gatekeepers. The Gateway-to-Gatekeeper Billing Redundancy feature provides redundant billing information to an alternate gatekeeper if the primary Gatekeeper to which a Gateway is registered becomes unavailable.
For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5400/sw_conf/ios_121/pulgwgkb.htm.

For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5400/sw_conf/ios_121/pull_bnd.htm.
H.323 Version 2 Support
Cisco H.323 Version 2 Support upgrades Cisco IOS software to comply with the mandatory requirements and several of the optional features of the version 2 specification. This upgrade enhances the existing Voice Over IP Gateway, the Multimedia Conference Manager (Gatekeeper and Proxy).
For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5400/sw_conf/ios_121/pullh323.htm.
Interactive Voice Response for Cisco Access Platforms
The Interactive Voice Response (IVR) feature allows the use of one of several interactive voice response scripts during the call processing. The TCL scripts are designed to interact with the IVR application software to perform the various functions. TCL scripts contain both executable files and audio files that interact with the system software. The IVR application is used for information gathering and processing purposes, such as accounting and billing.
For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5400/sw_conf/ios_121/pull_ivr.htm.
Interactive Voice Response Version 2.0 on Cisco VoIP Gateways
IVR Version 2.0 is the fourth release of IVR and TCL scripting on Cisco IOS VoIP gateways. The Cisco IVR feature (first made available in Cisco IOS Release 12.0(3)T and 12.0(7)T) provides IVR capabilities using TCL scripts.
IVR systems provide information in the form of recorded messages over telephone lines in response to user input in the form of spoken words. For example, when a user makes a call with a debit card, an IVR application is used to prompt the caller to enter a specific type of information, such as an account number. After playing the voice prompt, the IVR application collects the predetermined number of touch tones (digit collection), forwards the collected digits to a server for storage and retrieval, and then places the call to the destination phone or system. Call records can be kept and a variety of accounting functions performed.
For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5400/sw_conf/ios_121/pullskyn.htm.
Interworking Signaling Enhancements for H.323 VoIP
The Interworking Signaling Enhancements for H.323 and SIP VoIP feature enables VoIP networks to properly signal the setup and tear-down of calls, including generating in-band tones and announcements when needed at the originating or terminating switch. When a tone (for example, ringback, busy, reorder) or announcement (for example, "The number you have dialed is no longer in service") is played at the destination switch, the backward voice path from the called party to the calling party is cut-through early, so that the calling party can hear the tone or announcement. To prevent fraudulent calls, the voice path is cut-through in both directions only after the Connect message is received from the destination. The call progress indicator, which signals the availability of in-band communication, is carried end-to-end as required when interworking with ISDN and CAS protocols.
For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5400/sw_conf/ios_121/pul323pi.htm.
ISDN Network Side for ETSI Net5 PRI
The ISDN Network Side for ETSI Net5 PRI feature enables Cisco IOS to replicate the public switched network interface to a PBX that is compatible with the ETSI Net5 switch type.
For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5400/sw_conf/ios_121/puldtpri.htm.
Monitoring Voice and Fax Services on the Cisco AS5350 and Cisco AS5400 Universal Gateways
The universal port dial feature card (DFC) is a hardware card that processes voice and data services port technology for the Cisco AS5350 and Cisco AS5400. The ports on the Universal Port DFC support multiple types of service including modem, digital, voice, and fax. Ports can be aggregated at the slot level of the Universal Port module, the Service Processing Element (SPE) level within the Universal Port module, and the individual port level.
For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121newft/121limit/121x/121xm/121xm_5/ftupspe.htm.
Prepaid Distributed Calling Card via Packet Telephony
The Debit Card for Packet Telephony on Cisco Access Platforms is an application supported by the Cisco Interactive Voice Response (IVR) feature. The IVR voice scripts have been modified to use Tool Command Language (TCL) scripts.
The feature components consist of IVR functionality in Cisco IOS software that work in conjunction with an integrated third-party billing system. The Debit Card feature includes the ability to maintain per-user credit balance information through the use of a billing system. When these features are implemented, the billing system and IOS software functions enable a carrier to authorize voice calls and debit individual user accounts in real time at the edges of a voice-over-IP network, without requiring external service nodes. This feature uses vendor specific attributes (VSAs) to communicate with the billing system.
For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5400/sw_conf/ios_121/pull0134.htm.
Redundant Link Manager (RLM)
The goal of Redundant Link Manager (RLM) is to primarily provide a virtual link management over multiple IP networks so that the Q.931 signaling protocol and other proprietary protocols can be transported on top of multiple redundant links between the Cisco Signaling Controller (CSC) and the Network Access Server (NAS). In addition to this, RLM opens, maintains, and closes multiple links, manages buffers of queued signaling messages, and monitors whether links are active for link failover and Signaling Controller failover. The user can create more than one IP connection between the CSC and the NAS.
For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5400/sw_conf/ios_121/pull_rlm.htm.
Service Provider Features for Voice over IP
The Cisco voice Service Provider features include enhancements made to the functionality and configuration of both the gateway and the Voice over IP (VoIP) gatekeeper. The architecture of these features provides the Quality of Service (QoS), stability, and functionality necessary for carrier class, real-time IP communications services.
For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5400/sw_conf/ios_121/pulvoip1.htm.
Settlement for Packet Voice, Phase 2
The Settlements for Packet Voice, Phase 2 feature contains two features that were not in the first Cisco implementation of OSP (Settlement for Packet Telephony on Cisco Access Platforms): Roaming and PKI Multiple Roots.
For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5400/sw_conf/ios_121/pul0123b.htm.
SIP Diversion Header Implementation for Redirecting Number (CSCdr72341)
The SIP Diversion Header Implementation for Redirecting Number feature provides support for a new SIP header field; Call Control (CC)-Diversion. The CC-Diversion header field enables the SIP gateway to pass call control redirecting information during the call setup. Call control redirection is the redirection of a call based on a subscriber service such as call forwarding. Call redirection information is information is typically used for Unified Messaging and voice mail services to identify the recipient of a message. Call control rediversion information can also be used to support applications such as automatic call distribution and enhanced telephony features such as Do Not Disturb and Caller ID.
For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121rel/sipcfs/hennigan.htm.
T.38 Fax for Cisco Universal Gateways
A universal port dial feature card (DFC) is a hardware card that processes digital service port technology for the Cisco AS5400. Ports on the universal port DFC support multiple types of services such as modem, fax, digital data, and voice. The universal port DFC provides multiple port sessions, with each session capable of originating or terminating a session over a DS-0 in PCM format. The number of sessions depends on the port density of the card. You can manage your port connections at the universal port slot level, service processing element (SPE) level, or port level using monitoring and troubleshooting commands. A port is defined as an endpoint on a DFC card through which multiservice tones, voice, and data flow. There are six ports per SPE.
For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5400/sw_conf/ios_121/puldtfax.htm.
Voice over IP Q.SIG Network Transparency
Integration of Q.SIG enables Cisco voice switching services to connect private branch exchanges (PBXs), key systems (KTs), and central office switches (COs) that communicate by using the Q.SIG protocol.
The Q.SIG protocol is a variant of ISDN D-channel voice signaling. It is based on the ISDN Q.921 and Q.931 standards and is becoming a worldwide standard for PBX interconnection. By using Q.SIG signaling, the Cisco AS5300 can route incoming voice calls from a private integrated services network exchange (PINX) across a wide-area network (WAN) to a peer Cisco AS5300, which can then transport the signaling and voice packets to a second PINX.
For further details, please see http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5400/sw_conf/ios_121/pull0125.htm.

Open Caveats—Cisco IOS Release 12.1(5) XM2
This section documents possible unexpected behavior by Cisco IOS Release 12.1(5) XM2 and describes only severity 1 and 2 caveats and select severity 3 caveats.
•
On a Cisco AS5400 platform, when a configuration is copied from a TFTP server to the running configuration using the copy tftp running command, a low-memory error message is generated, even though there is sufficient memory. There is no workaround.
•
When the PPP Password Authentication Protocol (PAP)-password validation fails—that is, when the PPP PAP password is configured incorrectly—a slow memory leak occurs. There is no workaround.
•
On a Cisco AS5400, if the "Group-Async" interface has the ip address negotiated command enabled and the group-range command is removed while traffic is passing through the interface, the router reloads.
Workaround: Do not remove the group-range command while traffic is passing through the interface.
Alternative workaround: Instead of the ip address negotiated command, configure the ip unnumbered command on the "Group-Async" interface.
•
On a Cisco AS5400, if an NP108 card is hot-swapped with an NP60 card, the group-range command under the "Group-Async" interface does not change.
Workaround: Reconfigure the "Group-Async" interface.
Resolved Caveats—Cisco IOS Release 12.1(5) XM2
All the caveats listed in this section are resolved in Cisco IOS Release 12.1(5) XM2. This section describes only severity 1 and 2 caveats and select severity 3 caveats.
•
Cisco IOS software contains a flaw that permits the successful prediction of TCP Initial Sequence Numbers.
This vulnerability is present in all released versions of Cisco IOS software running on Cisco routers and switches. It only affects the security of TCP connections that originate or terminate on the affected Cisco device itself; it does not apply to TCP traffic forwarded through the affected device in transit between two other hosts.
To remove the vulnerability, Cisco is offering free software upgrades for all affected platforms. The defect is described in DDTS record CSCds04747.
Workarounds are available that limit or deny successful exploitation of the vulnerability by filtering traffic containing forged IP source addresses at the perimeter of a network or directly on individual devices.
This notice will be posted at http://www.cisco.com/warp/public/707/ios-tcp-isn-random-pub.shtml.
This caveat is resolved in Cisco IOS Release 12.1(5)XM2.
•
When running a Cisco SS7 Interconnect for Voice Gateways Solution configuration on a Cisco AS5400 platform, the output of the show isdn stat command might list call control blocks (CCBs) for calls that are no longer active. These CCBs might accumulate over time. There is no workaround.
This caveat is resolved in Cisco IOS Release 12.1(5)XM2.
Open and Resolved Caveats — Cisco IOS Release 12.1(5) XM1
