® IP Communications is a comprehensive system of powerful, enterprise-class solutions, including IP telephony, unified communications, IP video and audio conferencing, and customer contact. It helps organizations realize business gains by improving operational efficiencies, increasing organizational productivity, and enhancing customer satisfaction. Cisco CallManager is the software-based call-processing component of the Cisco enterprise IP telephony solution; it is enabled by Cisco AVVID (Architecture for Voice, Video and Integrated Data).
Cisco CallManager software extends enterprise telephony features and capabilities to packet telephony network devices such as IP phones, media processing devices, voice over IP (VoIP) gateways, and multimedia applications. Additional data, voice, and video services such as unified messaging, multimedia conferencing, collaborative contact centers, and interactive multimedia response systems interact with the IP telephony solution through Cisco CallManager open telephony application programming interfaces (APIs). Cisco CallManager is installed on Cisco 7800 Series media convergence servers (MCSs) and selected third-party servers. Cisco CallManager software is shipped with a suite of integrated voice applications and utilities, including the Cisco CallManager Attendant Console-a software-only manual attendant console; a software-only ad-hoc conferencing application; the Bulk Administration Tool (BAT); the CDR Analysis and Reporting (CAR) tool; the Real-Time Monitoring Tool (RTMT); a simple, low-density Cisco CallManager Auto Attendant (CM-AA); the Tool for Auto-Registered Phone Support (TAPS); and the IP Manager Assistant (IPMA) application.
FEATURES AND BENEFITS
Cisco CallManager Version 4.1 provides a scalable, distributable, and highly available enterprise IP telephony call-processing solution. Multiple Cisco CallManager servers are clustered and managed as a single entity. Clustering multiple call-processing servers on an IP network is a unique capability in the industry, and highlights the leading architecture provided by Cisco AVVID. Cisco CallManager clustering yields scalability of from 1 to 30,000 IP phones per cluster, load balancing, and call-processing service redundancy. By interlinking multiple clusters, system capacity can be increased up to one million users in a 100+ site system. Clustering aggregates the power of multiple, distributed Cisco CallManagers, enhancing the scalability and accessibility of the servers to phones, gateways, and applications. Triple call-processing server redundancy improves overall system availability.
The benefit of this distributed architecture is improved system availability, load balancing, and scalability. Call Admission Control (CAC) helps ensure that voice quality of service (QoS) is maintained across constricted WAN links, and automatically diverts calls to alternate public switched telephone network (PSTN) routes when WAN bandwidth is not available. A Web interface to the configuration database enables remote device and system configuration. HTML-based online help is available for users and administrators.
The enhancements provided by Cisco CallManager Version 4.1 offer improved security, interoperability, capability, supportability, and productivity as well enhancements to video telephony introduced in Cisco CallManager 4.0.
Cisco CallManager 4.1 has many security features that give Cisco CallManager servers and IP phones the ability to verify identity of the devices or servers that they communicate with, ensure the integrity of data they are receiving, and provide privacy of communications via encryption. The devices that can participate in secure communications now includes the Cisco IP Phone 7940G, IP Phone 7960G, IP Phone 7970G, and Media Gateway Control Protocol (MGCP) gateways. Secure administration and troubleshooting is now capable with CallManager 4.1 using HTTPS.
Improvements in the CallManager Q.SIG signaling interface expands the range of functions with which Cisco CallManager can connect to other Q.SIG compatible systems. Features like path replacement and call completion allow Cisco CallManager to integrate with other Q.SIG compatible systems closer than ever before. H.323 Annex M.1 support now gives users improved feature transparency between CallManager clusters.
Enhancements to the CallManager APIs (AXL, JTAPI, TSP) provide customers and 3
rd party vendors increased ability to develop improved applications that can be integrated with CallManager and IP Phones.
Other key features provided by Cisco CallManager 4.1 include call coverage, time-of-day routing and restrictions, forced authorization codes (FAC) and client matter codes (CMC) and enhancements for Video Telephony that was provided in Cisco CallManager 4.0.
New administration features such as Cisco Unity User Integration allow a CallManager system administrator to easily configure a Cisco Unity voice mail box while configuring an IP phone for that user.
• Cisco CallManager Version 4.1-Call-processing and call-control application.
• Cisco CallManager Version 4.1 configuration database-Contains system and device configuration information, including dial plan.
• Cisco CallManager administration software.

Reports that are provided include calls on a user basis, calls through gateways, simplified call quality, and a CDR search mechanism. In addition, CAR provides limited database administration; for example, deleting records based on database size.
• Cisco CallManager Bulk Administration Tool (BAT)-Allows the administrator to perform bulk add, delete, and update operations for devices and users.
• Cisco CallManager Attendant Console-Allows a receptionist to answer and transfer/dispatch calls within an organization. The attendant can install the attendant console, which is a client-server application, on a PC that runs Windows 98, ME, NT 4.0 (Service Pack 4 or greater), 2000, or XP. The attendant console connects to the Cisco Telephony Call Dispatcher (TCD) server for login services, line state, and directory services. Multiple attendant consoles can connect to a single Cisco TCD server. In Cisco CallManager Version 4.1, Attendant Console now supports accessibility enhancements for sight-impaired individuals.
• Cisco CallManager Real-Time Monitoring Tool (RTMT)-A client tool that monitors real-time behavior of the components in a Cisco CallManager cluster. RTMT uses HTTP and TCP to monitor device status, system performance, device discovery, and computer telephony integration (CTI) applications. It connects directly to devices by using HTTP for troubleshooting system problems.
• Cisco CallManager Trace Collection Tool-Collects traces for a Cisco CallManager cluster into a single zip file. The collection includes all traces for Cisco CallManager and logs such as Event-Viewer (application, system, and security), Dr. Watson log, Cisco Update, Prog logs, RIS DC logs, and SQL and IIS logs.
• Cisco Conference Bridge-Provides software conference bridge resources that can be used by Cisco CallManager.
• Cisco Customer Directory Configuration Plugin-Guides the system administrator through the configuration process for integrating Cisco CallManager with Microsoft Active Directory and Netscape Directory Server.

After the user installs and configures Cisco Personal Address Book, users can access this feature from the Cisco IP Phone Configuration Website.
• Cisco IP Telephony Locale Installer-Provides user and network locales for Cisco CallManager, adding support for languages other than English. Locales allow users to view translated text, receive country-specific phone tones, and receive TAPS prompts in a chosen language when working with supported interfaces. Install the Cisco IP Telephony Locale Installer on every server in the cluster. Click the icon to download one or more locale installers from the Web (you must have an Internet connection and a Cisco.com user account and password to download the executable).
• Cisco JTAPI-This plug-in is installed on all computers that host applications that interact with Cisco CallManager via JTAPI. JTAPI provides the standard programming interface for telephony applications written in the Java programming language. JTAPI reference documentation and sample code are included. Cisco CallManager Version 4.1 adds support for new features as well as the ability to disable device validation, which would allow applications to monitor or control a large amount of devices without requiring the devices to be specified in those applications' controlled device lists. JTAPI Device State Server is new in Cisco CallManager Version 4.1, as is notification of status (busy, idle, etc.) of a CTI device without having to monitor individual lines.
• Cisco Telephony Service Provider-Contains the Cisco TAPI service provider (TSP) and the Cisco Wave Drivers. Install the application on the Cisco CallManager server or on any other computer that is running a Microsoft Windows operating system that interacts with the Cisco CallManager server via TCP/IP (TAPI runs on the Microsoft Windows operating system). The Cisco TAPI Developer's Guide describes the TAPI interfaces that are currently supported. Install the Cisco TSP and the Cisco Wave Drivers to allow TAPI applications to make and receive calls on the Cisco IP Telephony Solution.

CISCO CALLMANAGER VERSION 4.1 ENHANCEMENTS
User Feature Enhancements
• Attendant Console has been "accessibility enabled" to simplify use for visually handicapped attendants.
– Works in conjunction with JAWS screen reader software.
– Shortcut keys provided for easy navigability; mouseless operation of Attendant Console is possible.
– Audible alerts provided to alert the user when certain events occur.
– Attempt to transfer, consult transfer, or conference a call results in the call being put on hold while the dial pad is displayed.
• Video has added the following new capabilities:
– Support for the SCCP H.264 video codec. The H.264 video codec delivers significantly higher quality at a given bandwidth than H.263. H.264 will be supported for intracluster SCCP calls only. Devices that will support SCCP H.264 include:
- Tandberg SCCP phones (550 and T1000)
- IPVC 3.6plus (3511 and 3540)
– Midcall video for Cisco VT Advantage-If both parties are SCCP video endpoints, the call will immediately become a video call. If one party is an H.323 endpoint, the call will become a video call. But if the H.323 endpoint rejects the incoming channel or does not open a channel, the video call will be either one-way video or no video.
– Video display mode for IPVC 3.6plus. IPVC 3.6plus will include a SCCP version of the message control unit (MCU) that supports both voice-activated and continuous presence videoconferencing modes. Video display mode is a softkey (called VidMode) that allows users on a SCCP videophone to toggle incoming videos between voice-activated and continuous presence mode.
– Participant information for IPVC 3.6plus. Cisco CallManager will provide participant information to the SCCP version of the IPVC MCU, including the user name and number. The IPVC MCU will display this information in the participant list on its Web management interface. The IPVC MCU can overlay this information in the video if it has an Enhanced Media Processor (EMP) module.
– Dynamic H.323 addressing (E.164 addressing)-H.323 clients can be configured in Cisco CallManager via an E.164 address. This simplifies H.323 client administration for deployments where H.323 clients are configured for DHCP. E.164 addressing can be paired with an Cisco IOS Software Release 12.3(8)T gatekeeper to simplify H.323 client dialing.
System Capability Enhancements
• BRI support-Support for secure communications using legacy BRI and analog secure endpoints (STE/STU) and support for IP-STE.
– V.150.1 Modem-Relay-over-IP support-Cisco CallManager will respond to the Session Description Protocol (SDP) sent by the gateway with default parameters. V.150.1 is required by the secure mode of IP-STEs and BRI-STEs.
– BRI station pre-emption.
• Call coverage-Cisco CallManager Version 4.1 provides the ability to set up coverage paths to route calls to individuals or groups, helping to ensure that calls are answered. Call coverage features include:
– Forwarding out of a coverage path.
– Ability to set up different coverage paths based on time of day, day of week, or day of year.
– Ability to provide separate forwarding treatment for internal versus external Call Forward No-Answer (CFNA) calls.
– Ability to provide separate forwarding treatment for internal versus external Call Forward Busy (CFB) calls.
– Support of a maximum timer for hunt lists.
– Ability to allow a line to appear in multiple line groups, which was a limitation in previous versions of Cisco CallManager.
– Ability to allow a gateway to appear in multiple route groups, which was a limitation in previous versions of Cisco CallManager.
– Ability to divert to a final forwarding location when a hunt list terminates, either through exhaustion or expiration of its maximum hunt timer. This location may be a dialed number (voicemail pilot, another hunt pilot, a route pilot, or any allowed dialed number) or a checkbox to select personal treatment based on settings for the original called party's line.
– Splitting the existing route-list/hunt-list GUI into two separate forms-one for hunt list and one for route list.
• Call display restrictions-Ability for the system administrator to block calling/called/connected name/number between certain phones. This is frequently used in areas where, for security reasons, this calling information cannot be displayed on phones. A hotel is an example where calls from room to room would not display calling information.
• Forced authorization codes/client matter codes
– Forced authorization codes-Allows a system administrator to require that an authorization code be entered prior to extending a call to a specific route pattern. This is often used as a mechanism to prevent fraudulent toll calls by individuals that might have access to the phones. The system administrator can assign authorization levels to allow some codes to have full calling capability and others to not be able to call certain numbers.
– Client matter codes or account codes-Ability for a system administrator to require that a client matter code be entered prior to extending a call to a specific route pattern. This code is often used by companies to track calls made to specific accounts and use this data for billing purposes.
– Client matter code and forced authorization code (CMC/FAC) information is recorded in the Cisco CallManager CDR database.
• H.323 FastStart-Support for inbound and outbound H.323 FastStart. This feature reduces the number of signals exchanged before voice is extended on a call. By using H.323 FastStart voice will be extended or cut-through using 10 less message exchanges. This can eliminate voice clipping connections that are separated by large distances with more than 50ms WAN delay. MTPs are required for outbound H.323 FastStart.
• MGCP BRI ETSI BRI basic-net3 (user-side only)-Allows a smaller, more cost-effective ISDN connection between Cisco CallManager and the PSTN for small offices where the cost of a Primary Rate Interface (PRI) is prohibitive.
• MLPP enhancements
– BRI station pre-emption.
– Support for MLPP-enabled, user-to-user information element (UUIE)-based PRI-4ESS interface.
– Executive override precedence level; gives an additional precedence level that was previously unsupported.
– Location-based MLPP through locations over intracluster and intercluster limited bandwidth WAN links.
– Support for intercluster MLPP.
– The signal information element, as described in 4.5.24 of ANSI T1.607.
• Q.SIG enhancements
– Alerting name-Support of alerting name presentation and restriction for Q.SIG facilities. "alerting name" is the capability to send and receive a CalledName application protocol data unit (APDU) encapsulated in a facility information element within the ISDN Q.931 message. This is an optional capability specified in ISO 13868 as part of the SS-CONP feature; it provides "alerting on ring" only. "Alerting on busy" (an optional service that provides the name of the called user who cannot be reached) is not supported by this feature.
– Call back/call completion-Support for ISO/IEC 13870: 2nd Ed, 2001-07 for Call Completion Supplementary Service:
- Call Completion to Busy Subscriber (CCBS)
- Call Completion on No Reply (CCNR)
– Call diversion by reroute in addition to call diversion by forward switching-Call Diversion Supplementary Service ISO/IEC 13872 and ISO/IEC 13873, first edition 1995.
– H.323 Annex M.1 (Q.SIG over H.323)-Delivers the Q.SIG feature set across intercluster trunks by the tunneling of Q.SIG messages by the Cisco CallManager over H.323, based on recommendations in the ITU recommendation for Annex M.1: "Tunneling of QSIG in H.323 07/2003". This development is limited to Q.SIG tunneling over Cisco CallManager H.323 intercluster trunks (both gatekeeper- and nongatekeeper-controlled). Interoperability between Cisco CallManager servers is the focus of this first release of Annex M.1.
– Path replacement-Replace the existing time-division multiplexing (TDM) circuit(s) in use between two parties on an active call with new ones, to use TDM resources more efficiently. The Q.SIG path replacement feature will be implemented based on ISO/IEC 13863 - 2nd Ed. 1998 and ISO/IEC 13974 - 2nd Ed. 1999.
• Security features
– Encryption to additional Cisco IP Phone 7940 and IP Phone 7960 devices, in addition to the already supported Cisco IP Phone 7970.
– Encryption for MGCP gateways.
– Encryption for SRST.
– HTTPS for secure administration of Cisco CallManager. Supported by the following applications:

- Extension Mobility
• T.38 fax support (H.323 only)-Support for T.38 fax when using H.323 gateways. When a fax call is placed, the call is initially established as a voice call. The gateways advertise capabilities during connection establishment. If both gateways support T.38, they will attempt to switch to T.38 upon fax tone detection by either gateway.
• Time of day, day of week, day of year routing/restrictions
– Ability to assign time schedules to partitions to determine when a phone, gateway, translation pattern, or route pattern can be reached. The time schedule can be based on time of day, day of week, or day of year. Using partitions, this feature can be used to assign time schedules for outbound calls (TOD restrictions) or inbound calls (TOD routing).
• Toll fraud improvements
– Ability to drop an ad-hoc conference when the conference originator hangs up
