Data Sheet

The Cisco® Unified Communications system of voice and IP communications products and applications enables organizations to communicate more effectively-helping them to streamline business processes, reach the right resource the first time, and impact the top and bottom line. The Cisco Unified Communications portfolio is a key part of the Cisco Business Communications Solution-an integrated solution for organizations of all sizes which also includes network infrastructure, security, and network management products, wireless connectivity, and a lifecycle services approach, along with flexible deployment and outsourced management options, end-user and partner financing packages, and third-party communications applications.

Cisco Unified CallManager is the call-processing component of the Cisco Unified Communications System. Cisco Unified CallManager 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 services such as unified messaging, multimedia conferencing, collaborative contact centers, and interactive multimedia response systems interact with the IP telephony solution through Cisco Unified CallManager APIs. Cisco Unified CallManager is installed on Cisco Media Convergence Server (MCS) 7800 Series of server platforms and selected third-party servers. It has a suite of integrated voice applications and utilities, including the Cisco Unified CallManager Attendant Console-a ad-hoc conferencing application, the Cisco Unified CallManager Bulk Administration Tool (BAT), the Cisco Unified CallManager CDR (call detail record) Analysis and Reporting tool the Cisco Unified CallManager Real-Time Monitoring Tool (RTMT), the Cisco Unified CallManager Auto-Attendant (CM-AA), the Tool for Auto-Registered Phone Support (TAPS), and the Cisco Unified CallManager Assistant application.


Cisco Unified CallManager Version 4.2 is an enterprise IP telephony call-processing solution that is scalable, distributable, and highly available. Multiple Cisco Unified CallManager servers are clustered and managed as a single entity. Cisco Unified CallManager clustering yields scalability of from 1 to 30,000 IP phones per cluster, load balancing, and call-processing service redundancy. Interlinking multiple clusters allows system capacity to reach 1 million users in a system of more than 100 sites. Clustering aggregates the power of multiple, distributed Cisco Unified CallManager installations, enhancing the scalability and accessibility of the servers to phones, gateways, and applications, and triple call-processing server redundancy improves overall system availability.
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. With Cisco Unified CallManager Version 4.2, devices can automatically update location information as they move from location to location to improve CAC and emergency service performance.
The enhancements provided by Cisco Unified CallManager Version 4.2 offer improved security, supportability, manageability, as well as usability enhancements to user features, including Park, Hunt Group, Cisco Unified CallManager Assistant, and Call Pickup features that have been supported in past releases.
The Call Park feature now allows users to park a call to a specific park slot. Users now also can have a busy-lamp-field (BLF) and speed-dial button that tells them whether or not the park slot is available. The feature is easily invoked by performing a transfer to the park slot.
With Cisco Unified CallManager 4.2, users now can log their phone into and out of hunt groups. The ability to log out of a hunt group results in shorter call answering times, because callers are not forced to wait for the Ring No Answer timer to expire before their calls proceed to the next phone in the hunt group.
Cisco Unified CallManager Assistant is a valuable application that allows administrative assistants to more effectively support their managers' IP phone activities. It has been ported to an Extensible Markup Language (XML) service that can be run on the phone, allowing assistants that handle executive or manager phones to have the increased features that Cisco Unified CallManager Assistant provides without having to rely on a PC to provide the user interface.
Call Pickup has been enhanced to give an audible and visual notification when a call comes in to the pickup group. Users no longer have to rely on hearing the phone ring to know that there is a call to pick up.
Many customers have security requirements for password aging and one-time passwords. Password complexity rules can now integrate with a Lightweight Directory Access Protocol (LDAP) directory such as Active Directory to provide these security features.
The management of mobile and remote devices is improved with Cisco Unified CallManager 4.2. Cisco Unified CallManager can now track devices as they move from one location to another by mapping the IP address of the phone to a list of configured locations, allowing emergency calls made by mobile devices to call out the correct gateway. This tracking also allows Cisco Unified CallManager to accurately track bandwidth and codec use for CAC purposes.
Call routing to remote phones connected to Cisco Unified CallManager over a WAN has been improved to allow alternate routing when the WAN is out of bandwidth or out of service. During a WAN failure or an out-of-bandwidth situation, the Cisco Unified CallManager can provide routing to the originally called phone number through the PSTN or can call an alternate phone such as a mobile phone.
Voice-quality troubleshooting and tracking has been improved on many of the Cisco Unified IP phones. The phones now report voice-quality statistics, such as mean opinion score (MOS), to help the user and system administrator track voice quality on a call-by-call basis. The phone models support this feature include: Cisco Unified IP Phone 7940G, 7941G, 7941G-GE, 7960G, 7961G, 7961G-GE, 7970G, and 7971G.

User Feature Enhancements

Call Pickup Notification-Members of a pickup group can receive an audible or visual notification when a call comes into their pickup group. Hitting the pickup soft key then allows them to perform the call pickup. The system administrator can configure the on-hook and off-hook tone and frequency. The default localized visual message displays "Call(s) available for pickup" on the status line on the phone. A delay timer can be configured to allow the originally called user to pick up the call first.

One-touch Call Pickup-This feature was first introduced in Cisco Unified CallManager 4.1(3). If the system administrator enables the "Auto Call Pickup Enabled" service parameter, the following behavior change occurs: when a call comes into the pickup group and the user hits the pickup soft key, the call is immediately picked up. This operation replaced the three-step operation of traditional Call Pickup: 1) Go on Hook, 2) Hit the pickup button, and 3) Hit the answer button.

One-touch Group Pickup-This feature was first introduced in Cisco Unified CallManager 4.1(3). If the system administrator enables the "Auto Call Pickup Enabled" service parameter, the following behavior change occurs: when a call comes into a pickup group other than the one the user belongs to, the user can pick up the incoming call by 1) hitting the GPickup soft key and dialing the pickup group number.

Other Group Pickup-This feature was first introduced in Cisco Unified CallManager 4.1(3). The system administrator can configure "other" pickup groups that are associated to a pickup group. When a call comes into the "other" pickup group, the user can hit the OPickup soft key to answer the call, thereby eliminating the need to remember and dial the pickup group number. If the pickup group that the call is coming in to is not configured as an "other" pickup group, the user can still use traditional group pickup to answer the call. Users do the following: 1) Hit the GPickup soft key and 2) Enter the pickup group number.

Directed Call Park with BLF for park slot-Users can park a call to a specific park slot. Directed Call Park is invoked with the transfer feature. To park a call users do the following:

– Hit the transfer soft key.

– Dial the park slot, hit the BLF button for the park slot, or use a speed dial.

– Hit the transfer soft key or hang up. ("Transfer On-Hook Enabled" service parameter must be enabled.)

A BLF or park slot busy button is provided that shows the status of the park slot (available or busy). To retrieve a parked call, the user simply dials the park retrieval code plus the park slot.
The traditional Call Park function is preserved with the Park soft key.

Log in or log out of Hunt Group-Users who have a phone that has directory numbers that belong to line groups (hunt groups) can log their phone out of all line groups by hitting the hlog soft key. After invoking the logout feature, a prompt status message "Logged out of Hunt Group(s)" displays the status of the login state. Hitting the hlog soft key a second time logs the phone back into the line group(s). A tone can be enabled by the system administrator to remind users to log back into the hunt group when they return to their phone.

Cisco Unified CallManager Assistant on the phone-An XML service makes it possible for a user to perform administrative functions on the phone without requiring PC interaction. The PC application is still supported, in addition to the XML service. This XML application supports the following screens:

– Login screen for the user to authenticate

– Manager Status screen-Shows manager the phone status and call indication and also has soft keys for many different Cisco Unified CallManager Assistant features

– Specific manager page-Allows the administrator to view specific information for that manager

– Continued support for important Cisco Unified CallManager Assistant features such as handling calls, Immediate Divert, Transfer to Voicemail, Filter Calls, Do not Disturb, etc.

Complete transfer by going on hook-This feature was first introduced in Cisco Unified CallManager 4.1(3). If the "Transfer On-Hook Enabled" service parameter is enabled, a user can complete a transfer by going on hook. Feature invocation is as follows:

– Hit the transfer soft key.

– Dial the number to transfer the call to.

– Go on hook.


Automatic-alternate-routing (AAR) support for forwarding calls on no bandwidth-New fields have been added to AAR that allow a system administrator to redirect calls to an alternate destination (or the original phone through the PSTN if SRST is installed) on a no-bandwidth condition. The new parameters also allow the call to be forwarded directly to centralized voicemail if desired.

Call forward on nonregistered-New forwarding conditionals have been added to the line administration page that give the system administrator the ability to forward calls to a destination that is different from the Call Forward No Answer destination. This setup allows Cisco Unified CallManager to route calls destined for phones at remote sites even when the WAN is down between the remote and central sites.

Device mobility-The system administrator can provide a mapping of IP subnets to device pool and location information. When a phone registers with Cisco Unified CallManager and has moved out of its home location, the Cisco Unified CallManager updates the device pool and location information to correctly reflect the location that the phone has moved to.

H.323 Overlap Sending and Receiving-Cisco Unified CallManager 4.2 now supports overlap sending and receiving for H.323 gateways and intercluster trunks. MGCP overlap sending that was supported in previous versions will continue to be supported.

H.323 Annex M.1 support for H.323 gateways and H.225 trunks-First introduced in Cisco Unified CallManager 4.1(3), this feature supports H.323 Annex M.1 for H.323 gateways and, in the future, for connection to other vendors' private branch exchange (PBX) through an H.225 trunk. At the release of Cisco Unified CallManager 4.2, no certification testing had been completed for interoperability with other PBX equipment.

MLPP enhancements-The following MLPP enhancements have been made:

– Interworking and tunneling of PRI 4ESS UUIE-based MLPP over an ICT-Allows MLPP information to be passed across an intercluster trunk

– DSCP-to-MLPP precedence-level mapping-Allows Cisco Unified CallManager to set the Type of Service (TOS) field in the IP header with the higher DSCP value based on the MLPP precedence level, determining the DSCP value to be used in the RTP media stream

V.150 secure modem support over an intercluster trunk-Although V.150 modem relay support was introduced in Cisco Unified CallManager 4.1, calls over an intercluster trunk could not support V.150. Cisco Unified CallManager 4.2 now supports V.150 calls across an intercluster trunk.


Support for password aging, complex password requirements, one-time passwords, etc. with LDAP directory-Customers who have these requirements can integrate with a supported LDAP directory that can provide these password maintenance functions.

Voice-quality statistics on a call-by-call basis-The Cisco Unified IP Phone 7940G, 7941G, 7941G-GE, 7960G, 7961G, 7961G-GE, 7970G, and 7971G calculate and send MOS and concealment information to Cisco Unified CallManager at the end of the call. This information is stored in the Call Maintenance Record (CMR) database and can be used by third-party or customer-developed applications to run reports and develop trends. The following information is transported and stored by Cisco Unified CallManager:

– Cumulative conceal ratio

– Interval conceal ratio

– Interval conceal ration maximum

– Conceal seconds

– Severely concealed seconds
