Call Back

The Cisco call back feature allows receiving of call-back notification on an IP phone when a called-party line becomes available. To receive call-back notification, a user presses the CallBack softkey upon receiving a busy or ringback tone when trying to reach a destination. Call-back notification can be activated on a line on an IP phone within the same CUCM cluster as the destination IP phone. Call-back notification cannot be activated if the called party has forwarded all calls to another...

Calling Privileges

Calling privileges are an important dial plan component. They are used to implement class of service (CoS), which restricts user calling capabilities. The calling restrictions are based on the calling device. Other applications of CoS include time-of-day call routing, vanity numbers, client matter codes (CMC), forced authorization codes (FAC), and private line automatic ringdown (PLAR).

CUCM Overview

Cisco Unified Communications (UC) is an IP-based communications system integrating voice, video, data, and mobility products and applications. It enables more effective, secure communications and can transform the way in which we communicate. UC represents a communications paradigm shift like that of the invention of the telegraph. UC removes the geographic barriers of effective communications through the use of voice, video, and data integration. Business can be conducted with a fluidity that...

Digit Manipulation

Users of a phone system need to communicate with a variety of destinations. Destinations are located within the same site, different sites within the same company, and other companies located within the same country or different countries. Completing various types of calls often requires dialing access codes or prefix numbers. It is often prudent to restrict users from dialing certain destinations that incur high costs, such as 1-900 numbers. Users should be provided with a dial plan with the...

Endpoint Addressing

Reachability of internal destinations is provided by assigning directory numbers (DN) to all endpoints (IP phones, fax machines, and analog phones) and applications (voice mail, auto attendants, and conferencing systems). The number of dialable extensions determines the quantity of digits needed to dial extensions. A four-digit abbreviated dial plan cannot accommodate more than 10,000 extensions (from 0000 to 9999). A leading digit of 0 is normally not used in dial plans because it is dedicated...

Endpoints

An important task of supporting a Unified Communications (UC) deployment is managing the endpoints. It is important to be able to distinguish between various Cisco UC endpoints that you may encounter during the course of deploying and administering a CUCM network. Understanding the boot and registration communication between a Cisco IP Phone and CUCM can be very valuable for troubleshooting purposes. This lesson describes the various models of Cisco IP Phones and how they work within a Cisco IP...

Intercom

Intercom functionality is normally leveraged between administrative assistants and managers. The administrative assistants should not be allowed to hear the manager's conversation, but the manager would like immediate communication from the administrative assistant when, for example, an important business client is on hold at the administrative assistant's phone. The CUCM intercom function allows a user to call a line of another user, which autoanswers with the line muted. The line must be...

License Manager

The license manager acts as a broker between CUCM applications that use licensing information and the license server. The license manager receives requests from the CUCM applications and forwards the requests to the license server. The license manager then responds back to the application after the request has been processed by the license server. The license manager acts a licensing proxy server. An administration subsystem and alarm subsystem complete the functional diagram. Details of these...

Media Resources

A media resource is a software- or hardware-based entity that performs media processing functions on the data streams to which it is connected. Media processing functions include mixing multiple streams to create one output stream (conferencing), passing the stream from one connection to another (MTP), converting the data stream from one compression type to another (transcoding), echo cancellation, signaling, termination of a voice stream from a time-division multiplexing (TDM) circuit (coding...

Number of DLUs

License files are additive. (Multiple license files can be loaded.) The Cisco FlexLM process is used to obtain licenses, and integrity of license files is assured by a digital signature. When upgrading from Cisco Unified CallManager 4.x, the number of DLUs required is calculated during the CUCM migration process, and an intermediate XML file containing these license counts is generated. The number of devices and servers that are in the database at the time of migration is the basis for the...

Obtaining Additional Licenses

The process of obtaining additional DLUs and node licenses is as follows 1. The customer places an order for the additional licenses for a license server (publisher MAC address has to be specified). 2. When the order is received, Cisco.com generates a license file with the additional count and sends it to the customer. 3. The new license file has to be uploaded to the license server and will be cumulative. Consider this example. A CUCM server has an existing license file that contains 100 DLUs....

Phone Configuration Element Relationship

In Figure 9-14, an NTP reference is applied as an element to the date time group, and the date time group is applied as an element of the device pool configuration. The device pool is one of the elements in the device record of an IP phone, allowing the IP phones to inherit settings configured at the device pool level. Some elements can be applied to both the device pool and the phone configuration, in which case the value applied to the phone configuration will have higher priority. The...

Phone Configuration for Voice Mail Usage

Call Classification

Route patterns are classified as off-net (by default) if the Provide Outside Dial Tone check box is selected in the route pattern. The assumption is that the route pattern is being used to route a call off of the cluster. The Allow Device Override parameter can be checked at the route-pattern level. The device override changes the call classification method for outgoing calls if the device the call is routed over has a different call classification than the route pattern matched. The device...

This lesson introduces and describes the role, architecture, hardware and software requirements, and the licensing model of the...

Example Basic IP Telephony Call

Figure 1-4 illustrates a user at phone A placing a call to phone B. At the beginning of a call, a user at IP phone A picks up the handset, and a message is sent to CUCM letting CUCM know that the device has gone off-hook. CUCM responds to this stimulus by replying with a message that tells the device to play the dial tone file that is stored in the flash memory of the phone. The user at phone A hears the dial tone and begins dialing the phone number of phone B. SCCP phones send their digits to...

And Vanity Numbers

911 is a single number to call for medical, fire, and police emergencies in the United States and Canada. Calls to 911 are routed to a public safety answering point (PSAP). The PSAP is the first-tier triage call center for emergency calls. PSAP operators dispatch medical, fire, and police resources as necessary. Emergency calls have to be sent to a local PSAP through the local gateway. In a multisite deployment, all emergency calls are placed to the same number, but they need to be routed...

Endpoint Configuration Tools and Elements Overview

There are four ways to add IP phones to CUCM Bulk Administration tool (BAT) Tool for Auto-Registered Phone Support (TAPS) Auto registration allows Cisco IP Phones to be added to CUCM without the administrator having to first compile a list of MAC address for the endpoints. Auto registration automatically populates phone configuration data, so it is impossible to migrate phone settings from the existing phone system. Configuration changes can be made to the phone using CUCM Administration. CUCM...

Translation Patterns

CUCM uses translation patterns to manipulate digits before routing a call. The translation pattern can also be used to block certain patterns. Translation patterns are useful to manipulate the caller ID of incoming PSTN calls to allow the users to quickly return phone calls using the redial and missed-calls functionality. The caller ID from the PSTN may include only 10 digits while the system requires 11 digits prefixed with an access code of 9 to properly route outgoing calls. The translation...

CUCM Single Site Deployment

As illustrated in Figure 2-1, the Single-Site model for CUCM consists of a CUCM cluster located at a single site, or metropolitan-area network (MAN), with no telephony services provided over a WAN. All CUCM servers, applications, and digital signal processor (DSP) resources are located in the same physical location. An enterprise would typically deploy the Single-Site model over a LAN or MAN, which carries the voice traffic within the site. In this model, calls beyond the LAN or MAN use the...

Hold Reversion

When a call is put on hold with the Hold softkey and the duration exceeds the holdreversion timeout limit, CUCM generates alerts to the phone to remind the user to handle the call. Hold reversion is illustrated in Figure 16-8. Initial Call ----Hold Reversion -Second Call Initial Call ----Hold Reversion -Second Call The types of alerts that are generated at the phone for reverted calls depend on the capabilities of the phone device. CUCM provides the following alerts when the Hold Reversion...

Uniform OnNet Dial Plan Example

A dial plan should be designed so that all extensions within the system are reached in a uniform way. A fixed number of digits is used to reach a given extension from any on-net origination point. Uniform dialing is desirable because of the simplicity it presents to users. A user does not have to remember different ways to dial a number when calling from various locations. Table 11-1 is an example of a four-digit uniform on-net dial plan. Various sites in Table 11-1 were assigned numbers in the...

Transformation Examples

Multiple transformations might take place when placing a phone call. Using external phone number masks instructs the call-routing component to use the external phone number of a calling station rather than its DN for caller ID information. The external phone number mask is applied on an individual line basis through the Directory Number Configuration screen on the device. The route pattern matched for an outgoing call can apply another set of calling-party transformations before extending the...

H323 Endpoint Support

H.323 phones support multiple lines and can be audio, video, or data networking endpoints. H.323 terminals are synonymous with endpoints. The H.323 terminal language is used in the H.323 standard. CUCM supports voice calls from H.323 terminals natively. CUCM can also integrate with H.323 video endpoints using an H.323 gatekeeper. Cisco Unified Communications IP Telephony, Part 2 explains the H.323 video integration in further detail. H.323 phones do not register with CUCM. H.323 devices are...

IP Phone Services

Typical IP phone services that might be supplied to a phone include weather information, stock quotes, and news. Deployment of Cisco Unified IP Phone services occurs using the HTTP protocol from standard web servers, such as the Apache web services. A user can access a service from the supported phone model in two ways. The user can press the Services button, or the user can use a preconfigured phone button. When the user presses the Services button, the phone uses its HTTP client to load a...

Presence Policies

CUCM Presence has multiple ways of limiting Presence information. Presence-enabled speed dials are configured statically by the CUCM administrator and cannot be configured or modified directly by a user. The administrator maintains control of the monitored Presence entities for each watcher. Subscribe calling search spaces (CSS) also apply to Presence-enabled speed dials. Access control for Presence-enabled call and directory lists can be provided by partitions and subscribe CSSs and by...

Partitions and Calling Search Spaces

Cucm Partition And Css

A partition is a group of dialable patterns with similar accessibility. Any dialable pattern can be assigned to a partition. All phone numbers are in the null partition by default, and all devices have access to the null partition. As soon as a phone number is assigned to a different partition, the devices in the network will not be able to access that phone number without the configuration of a calling search space (CSS). A CSS defines which partitions are accessible to a particular device. A...

Timeof Day Call Routing

Time-of-day routing can be implemented in CUCM by applying time and date attributes to partitions using time schedules and time periods. Time periods define time ranges or dates and are grouped into time schedules. Time schedules are then assigned to partitions. A CSS that includes a partition that is associated with a time schedule has access only to the partition if the current date and time match the time and date information specified in the time schedule that is associated with the...

Media Gateway Control Protocol Gateways

MGCP is a plain-text protocol used by call-control devices to manage IP telephony gateways. MGCP (IETF RFC 2705) is a master slave protocol that allows a call-control device (CUCM) to take control of a specific port on a gateway. MGCP has the advantage of centralized gateway administration and provides for scalable IP telephony solutions. CUCM controls the MGCP state of the configured ports of the gateway. MGCP allows centralized administration of the dial plan and gives CUCM per-port control...

CUCM Transformation Masks

Dialing transformations allow the call-routing component to modify either the calling (initiator) or called (destination) digits of a call. Transformations that modify the calling number (automatic number identification, ANI) are calling-party transformations transformations that modify the dialed digits (dialed number identification system, DNIS) are called-party transformations. Transformation masks use mask operations that allow the suppression of leading digits, the modification or...

Class of Service Approaches

CoS applications in CUCM can be summarized as two distinctly separate implementations the traditional approach and the line-device approach. This section investigates the difference between these two approaches and explains the advantages of using the linedevice approach. Figure 13-22 shows a simple single-site CoS deployment with four distinct classes of service. Four partitions and four CSSs have been created. The route patterns for each call type have been put into their respective...

Route Filters

Route filters can be used only with the route pattern to match certain elements or special numbers of a numbering plan. A route filter applied to a pattern not containing the wildcard is ignored. The logical expression entered with the route filter can be up to 1024 characters, excluding the Not-Selected fields. For large-scale deployments, use explicit route patterns rather than the wildcard and route filters. This practice also facilitates management and troubleshooting because all patterns...

Client Matter Codes and Forced Authorization Codes

Client matter codes (CMC) and forced authorization codes (FAC) can be applied to route patterns. CMCs are typically used in professional organizations where a great deal of business is transacted over the phone and clients are billed for such time. The CMC is added to call details records (CDR) to allow accounting and billing of calls based on their client matter. If a route pattern that has a CMC applied is matched, the user is prompted to enter a CMC for the call to be extended. Valid CMCs...

Multisite WAN with Centralized Call Processing

The Multisite WAN with Centralized Call Processing model consists of a centralized CUCM cluster that provides services for many sites and uses the IP WAN to transport IP telephony traffic between the sites. The IP WAN also carries call-control signaling between the CUCM cluster at the central site and the IP phones at the remote sites. Figure 2-2 illustrates a typical centralized call-processing deployment, with a CUCM cluster at the central site and an IP WAN with QoS enabled to connect all...

Media Resource Support

CUCM offers software-based media resources. Start the IP Voice Media Streaming application to activate the following The following media resources are available only in hardware Audio conferencing and MTP media resources can also be offered by hardware media resources. MoH is a special case. Because of the potential WAN bandwidth utilization of MoH, the multicast streams of the server are normally scoped at the headquarters. Survivable Remote Site Telephony (SRST) can stream one media resource...

MGCP Configuration Server

When you are using the Configuration Server feature, the gateway- and interface-specific MGCP configuration commands are provided by CUCM in the form of an Extensible Markup Language (XML) configuration file that is downloaded by the Cisco IOS gateway from the CUCM TFTP server. This is the recommended approach to integrate Cisco IOS MGCP gateways with CUCM. The Cisco IOS gateway dynamically loads the necessary MGCP configuration commands from the XML file downloaded from the TFTP server. When...

Endpoint Basic Configuration Elements

There are mandatory and optional configuration details. It is advisable to never use any of the default mandatory items. Three examples of this are the call manager group, region, and location. The device pool and region do not need to be specified, but they are mandatory. The default values will not work in most environments, but they can be modified. Instead of modifying the default values, these elements can be copied, renamed, and reconfigured. Rename the elements in a way that allows the...

Network and Feature Services

A CUCM cluster can consist of up to 20 servers. Each server can fulfill different tasks, such as running a TFTP or DHCP server, being the database publisher, processing calls, providing media resources, and so on. Depending on the usage of a server, different services have to be activated on the system. There are two types of services on CUCM servers Network services Network services are automatically activated and are required for the operation of the server. Network services cannot be...

Music on Hold

CUCM may be configured to provide MoH. The MoH feature has two main requirements An MoH server must provide the MoH audio stream sources. CUCM must be configured to use the MoH streams provided by the MoH server when a call is placed on hold. The integrated MoH feature enables users to place on-net and off-net callers on hold with music instead of the default one on hold. The MoH source makes music available to any on-net or off-net device placed on hold. On-net devices include Cisco IP Phones...

Hardening Cisco IP Phones

The IP phone is a target for attacks, just like all other components of the network. IP phone endpoints should be protected in a similar manner to servers in the environment. IP phones have default settings that make them vulnerable to attacks. There are several options available to harden IP phones and thus protect them against various attacks and infiltration methods. The product-specific configuration parameters of Cisco IP Phones are set by default to achieve the greatest functionality but...

Presence Support in CUCM

CUCM Presence is natively supported by CUCM, with no extra products or servers required. It allows an interested party (watcher) to monitor the real-time status of a DN (Presence entity). A watcher subscribes to the status information of one or more Presence entities. The status information of a Presence entity can be viewed using Presence-enabled speed dials or Presence-enabled lists call lists such as placed, received, or missed calls and public directory lists. The status can be one of the...

SIP Third Party IP Phone Support in CUCM

CUCM supports RFC 3261-compliant third-party SIP phones. Support for third-party SIP phone features varies greatly from Cisco SIP IP Phone features. Third-party phones have only RFC 3261 SIP Version 2 support, whereas Cisco SIP Phones have many Cisco SCCP features that have been rewritten to work in a native SIP protocol stack.

CAST is also used to send signaling information for video streams from the IP...

CUCM Path Selection

Homeschool Daily Log Sheets

Path selection is an essential dial plan element. After matching an entry in the call routing table, CUCM has to select how and where to route the call. Most CUCM calls are routed across IP trunks or gateways. CUCM allows multiple paths to be configured for a route pattern for resiliency purposes. Figure 11-11 shows a scenario in which a user has dialed a long-distance PSTN number starting with an access code of 9, 1 for the long-distance operator, 408 for the area code, followed by 526 for the...

Voice Mail Integration

CUCM can integrate with Cisco Unity via either Skinny Client Control Protocol (SCCP) or Session Initiation Protocol (SIP). Cisco Unity telephony integrations are configured with the Cisco Unity Telephony Integration Manager (UTIM). In addition to the option of adding multiple clusters by adding additional integrations for each new CUCM cluster in Cisco Unity, CUCM supports Annex M.1, Message Tunneling for Q Signaling (Q.SIG), which allows administrators to enable Q.SIG on intercluster trunks...

IP Phone Auto Registration

Auto Registration Cucm

Auto registration allows CUCM to issue extension numbers to new IP phones, which is similar to the way in which the DHCP server issues IP addresses. With auto registration configured and enabled, when a new IP phone boots and attempts to register with CUCM for the first time, CUCM issues an extension number from a configured range. After CUCM issues the extension, it adds the phone to its configuration database with the used device ID (MAC address) and the assigned extension. If a specific...
